INNOVATION IN ROLLER-BASED LINEAR SYSTEMS
The complete modular linear system MODULARACE is
designed around double row precision ball-bearing rollers, with
high radial and axial load capacities, and raceways with a
protruding truncated cone-shape. The complete system has
hardened and honed raceways and a surface treatment for
high resistance to wear and corrosion. Thanks to the many
combination possibilities, a wide range of linear rails have been
developed within MODULARACE, to satisfy the demand for
strong reliable linear systems, for medium precision applications
and general automation.
Two rail designs and different size rails are available: The
MR-rail with internal raceways (RAILRACE) and the FXR-rail
with external raceways (FLEXRACE). They both have the
same protruding truncated cone raceway shape, but the
FLEXRACE has multi direction raceways.
The rails are all completely surface hardened. The innovative
hardening treatment also offers a standard high wear and
corrosion protection, assuring long life for the whole system.

The ROLLERACE rollers are designed around a double-row
precision ball bearing to guarantee both high radial and axial
load capacities. The rollers are protected by a double lip sealing
system (2RS) to assure long lifetime, even in difficult
environments. The integrated roller pivot has concentric or
eccentric shape, to allow for preload setting in the different
systems.
The rollers external ring comes with 2 slightly different profiles:
The Guiding-roller, assures system precision and load/moment
capacities in all directions, while the Floating-roller provides
limited lateral movement and minor rotation around its axis,
which allows for certain structural/assembling errors.
ROLLERS:
• The guiding roller is locked onto
raceways’ angled surfaces, for
precise slider guiding and ensuring
both radial and axial load
transmission.
Loading rollerGuiding roller
Guiding roller with eccentric pivot - REVGuiding roller with concentric pivot - RCV
Floating roller with concentric pivot - RCP Floating roller with eccentric pivot - REP
• The Floating roller touches only the raceways
central surface, due to wide central area of the
outer ring of the bearing. Hereby enabling only
radial load capacities. Thanks to this design,
the roller can move axially and rotate slightly
around its axis. As described further in the
TWINRACE part, the combination of Guiding
roller and Floating rollers in the TWINRACE
sliders offers a system which can absorb certain
structural/assembling misalignment errors.

SLIDERS:R
The sliders are available in three
sizes ( 18mm – 28mm – 43mm) with
3 or 5 rollers and each size in three
versions : Guiding (RV), Floating
(RP) and Rotating (RA);
The adjustable rollers are easily
identified, as the holes for the
eccentric pivot screw are clearly
visible on the slider’s body strap. The
non-adjustable (concentric) fixed
rollers, have all their central thread
totally covered by the slider body’s
black label.
Since the rollers are positioned
asymmetrically in the slider, the
correct slider orientation in the rails
is therefore important, to assure that
max. radial load is directed towards
the raceway with the highest number
of rollers.
The load direction is indicated by two
ingraved points.
The RACER (R) slider is equipped
with strong raceway wipers to keep
the raceways clear and smooth, while
lateral longitudinal seals assure good
overall dust protection.
The strong raceway wiper system,
incorporates greased sponges to
guarantee proper lubrication of
raceways for life, under clean
standard environment. (see page 44
for Maintenance).
Indication on the slider of right
load direction.
For general use, it is
sufficient to fix the 3-roller
sliders with only 2 screws.

This is a fully versatile system thanks
to the unique rails, which allow multi
radial-load directions. This system
is composed of one or more FXR-
rails, and ROLLERACE (R) rollers.
FLEXRACE is a Low-cost linear
precision system for fast and
easy assembly.
The many possible different rail-
combinations, solve a wide
variety of linear applications, as
shown below and on page 38-40. A
typical application example is for
moving doors and shields on
equipment.

Modular System‘s four product families
The MONORACE system is a rigid linear system, used with
one or two rails. The system is composed of MRL-MRS-rails
and RV guiding sliders, which use guiding rollers, type RCV-
REV.
Thanks to its optimized design, the Monorace system
guarantees load and moment capacities much higher than any
competitive product.
When used as a single rail, the system allows for loads and
moments in all directions.
When more than one rail is used, the rails must be well aligned
to assure smooth movement without binding.
STANDARD LINEAR SYSTEM:
SELF-ALIGNING TELESCOPIC RAILS:
The TWINRACE system is designed as a self-aligning linear
solution, capable of compensating for low accuracy mounting
surfaces or assembling errors. The system is composed of
two parallel MRL/S-rails and RA – RP-sliders. One rail
assembled with RA-sliders, assures precise movement, while
providing some slider rotation to compensate for horizontal
misalignment. The other rail mounted with RP-sliders, which
in addition to horizontal compensation; also compensates for
parallelism errors, as the slider allows for some lateral
movement, while maintaining its original preload.
A truly self-aligning system, which guarantees precise
straight-line movement, with no play, but with the benefit
of lower assembly cost.
SELF-ALIGNING LINEAR SYSTEM:
The TELERACE system is the world’s only telescopic rail system
for complete extension, based on precision rollers and hardened
raceways and with incorporate self-aligning feature (TLR series).
The system offers unique possibilities for all kinds of automation
applications, where smooth and precise telescopic movement is
required. Optimal movement with no play for High-Tech telescopic
applications, or for even heavy load and high frequency applications.
The TELERACE system is composed of exactly the same
precision components as the MONORACE and TWINRACE
system, except that the slider bodies are different, as longer
and with more rollers. All telescopic rails feature strong raceway
wipers and greasing system for low maintenance.
The TLR telescopic rails offer unique self-aligning capability, when
used in pair. As the right telescopic rail TLRD, allows the RA-like-
sliders to rotate in the lower rail-element, to compensate assembling
or surface misalignment errors, while maintaining the same precise,
preloaded extension.
To guarantee high load capacities and low deflexion, the TLR
telescopic rails are fixed to an intermediate S-shaped steel plate.
The TLQ telescopic rails have the MR-rails functioning as the
intermediate element, offering good radial and axial load capacities,
with very compact overall dimensions.

SELF-ALIGNING LINEAR SYSTEM
In most cases, when a pair of linear rails
are needed, the TWINRACE system
can be used with great advantages to
compensate for rail misalignment and
low accuracy of mounting surfaces,
thanks to the TWINRACE unique
features. The system is designed so that
one rail is assembled with RA-sliders,
assuring precise movement, meanwhile
capable of some slider rotation to
compensate for axial misalignment. The
other rail
mounted
with RP-
sliders, which
in addition to
axial misalignment
also compensates for
longitudinal parallelism
errors, as the slider allows
some free lateral movement,
while maintaining its original
preload and same precise straight-
line movement.
The “Rotating” RA- sliders are
mounted with two or three guiding
R_V-rollers (depending if slider
has 3 or 5 rollers in total), which
are aligned against the same lower
raceway for max. radial load
capacity. While one or two
(depending if slider has three or
five rollers in total) floating R_P-
rollers are mounted against the
upper raceway. This configuration
allows the RA-slider a minor
rotation, around the contact points
of the lower raceway. This
compensates for axial
misalignment, while maintaining
its original preload and same
straight, precision motion.The idea behind the concept is to offer
the engineers a compact linear system,
which provides assembly cost savings,
for the wide range of medium precision
applications. The target market for
TWINRACE is the medium accuracy
applications, where the precision of
recirculating linear guides is not needed.
TWINRACE yields savings in these
applications through lower cost. Reduced
assembly time, custom allignment at
assembly and product precision
requirements for the mounting surfaces.

“Floating” slider RP series. “Rotating” slider RA series.
The “Floating” RP-sliders contain
only floating R_P rollers, three or
five in total. The contact areas with
the raceways only provide for
radial load and Mz capacities, thus
allowing for axial movement and
a simultaneous slight rotation of
the slider to offer axial and
longitidinal compensation, while
maintaining original preload and
same precise and smooth straight-
line movement.
As for the MONORACE system, also
the TWINRACE system is available
with MRL and MRS-rails. When the
fixing holes are descent aligned or
usage of T-slot in profiles, it becomes
natural for most applications, to use
the self-aligning MRS rails with
countersunk fixing holes, for easy
and fast rail assembling.
The radial load and Mz moment
capacities remains the same as for
MONORACE system, while axial load
and My – Mx moments are generally
not present in a configuration of two
parallel linear rails.

SELF-ALIGNING TELESCOPIC SYSTEM
The TLR and TLQ rails are the world’s
only telescopic rail system which
incorporates self-aligning feature to
absorb parallelism errors of the
mounting surfaces.
The TLR telescopic rails are designed
for heavy duty High-Tech telescopic
applications, with precise motorized
movement, requiring constant smooth
sliding performance with no play.
The special smooth operating
performance is due to double-row
precision bearings, strong rails with
hardened and honed raceways, fixed
to a rigid intermediate S-shaped steel
plate, assuring high load capacities
and low deflexion at even fully
extended position.
The TLR telescopic rails assure
unique self-aligning capability, when
used in pairs.
COMPENSATION OF ASSEMBLING/SURFACE ERRORS
The right telescopic rail TLRD, allows
the RA-like-sliders to rotate with no
play, in the lower rail-element to
compensate for surface
misalignments, while the rigid left
TLRS telescopic rail, maintains a
stable and precise extension.
TLR system offers unique possibilities
and benefits for all kind of automation
applications with variable telescopic
strokes, which until now have been
troubled by common friction and
breakdown problems, during the ball-
cage rephasing when using of old-
type ball-cage telescopic rails.
To assure max. load capacity the
telescopic rail must be correctly
positioned according to the rollers’
positioning, - which are non-symmetric
and with different position in upper –
lower rail element.
Therefore the extended part must
always be fixed to the lower rail, which
is identified by the letter B.
All TELERACE telescopic rails
guarantee maintenance free
operation, thanks to strong raceway
wipers and longitudinal seals for dust
and impurity protection, and an
integrated lubef for-life greasing
system, assuring a constant thin layer
of lubrification on the raceway
surfaces.
All TELERACE telescopic rails are
equipped with internal end-stops,
only designed to drag the
intermediate element. It is therefore
highly recommended not to use these
internal end- of stroke travel limits as
functional terminals; strong external
end-stops must be added.
The TELERACE’s load capacities
are intended at half extension (L/2)
as indicated in by letter “P” in below
drawing. Unlike ball-cages drawer
slides, the TELERACE max. load
capacities are based on continuously
non-stop operation.
Version S = Left side Version D = Right side

Left side telescopic rail, size

Right side telescopic rail, size

Therefore a straight load comparison
with other telescopic rails isn’t
possible, as these load capacities
are merely a static load capacity,
based on low daily frequency.
To offer a wide range of load
capacities and extensions, the TLR
telescopic rails come in 2 dimensions.
The TLR.80, based on 28mm rails
with outer height of 80mm and
TLR.116, based on 43mm rails, with
outer height of 116mm. Both rails
come with an overall black finish.

TELESCOPIC RAIL TLR116 SERIES
In the case of horizontal panel
extension, we recommend the use
of a pair of TLR and TLQ, as the TLR
can absorb some lateral structural
misalignments on the vertical axis.
TLQ system assures smooth
extension for all kinds of automation
applications with variable telescopic
strokes, which until now have been
troubled by common friction
breakdown problems, during the ball-
cage rephasing, when using typical
drawer slides. Same rephase
problem or even deformation of the
ball-cages, occurs for all vertical
applications, as the ball-cage in such
telescopic rails, constantly tend to
move downwards, so extra friction is
generated with each stroke, during
the repositioning of the ball-cages.
To assure max. load capacity the
telescopic rails must be correctly
orientation, assembled.
The extended part must always be
fixed to the shortest slider, identified
by the letter B.
The very compact TLQ telescopic
rails are designed for High-Tech
telescopic applications with precise
motorized movement, requiring
constant smooth sliding performance
with no play.
The squared designed is obtained
by using two MR-rails with hardened
honed raceways, as the rigid
intermediate element, into which the
sliders are assembled. The TLQ
telescopic rails offer both high radial
and axial load capacities.
The rail/slider configuration allows
the TLQ telescopic rails to be
mounted not only at the side, but also
underneath the moving part, when
there are space limitations at the
sides, or to be used in typical vertical
applications. See below tables and
figures.
A right (TLRD) version and a left (TLRS) version are available. Must be ordered so, when working in pair.

VERSATILE LINEAR SYSTEM
The FLEXRACE system provides an
extremely versatile linear system, with
great variety of rail configurations for a
wide range of applications.
FLEXRACE is designed to be a strong
and simple multitask linear system for
larger handling and automation
applications. It is a Low -cost, easy to
assemble system, that offers smooth
motion even on inaccurate surfaces.
1. Wide-base configurations for
high cantilever moments.
With external slider/structure
2. Combined solutions to obtain telescopic systems.
With internal slider/structure
3. Solutions with
flat mounted rails.
4. Applications for doorsand shields.
It is also possible to assemble a
combination of guiding (REV43-
RCV43) rollers and loading rollers
(REP43-RCP43), to obtain linear
system which can compensate
structural misalignments.

FXR RAIL WITH ROLLERS
Roller assembling to mobile part The position and number of rollers
depends on the size, weight and force
applied on the moving element, see
also pages 42-43 for further
indications.
In general, the rollers should be
positioned, along the axis upon which
the radial-load is applied. When the
moving part is just resting on the rails,
only concentric rollers are assembled.
For applications where a guiding
slider/support is constructed, a
combination of concentric rollers and
eccentric rollers must be used, see
example figure A. Only the eccentric
rollers allow for preload setting. For
application with a guiding
slider/support, similar to figure A, but
with the rails positioned far apart, it
is recommend to assemble loading
rollers REP43 in lower rail, when only
radial loaded.
In case more than 2 rollers are
mounted on the same rail, it is
recommended to use 2 concentric
rollers at the two ends of the moving
part and all remaining central rollers
of the eccentric REP or REV type, in
order to eliminate as much as
possible of roller misalignment, by
having a max 0,8mm displacement
of the roller, ref. below figure B.
The ROLLERACE rollers coded with
the middle letter E ( REV or REP)
have an eccentric integrated pivot,
which allows for a clearance-preload
adjustment of the linear system.
The assembled sliders are normally
supplied with a standard preload
setting, according to the MR-rail it is
supplied with, ensuring maximum
smoothness with no play.
Roller preload setting
For more detailed information on ROLLERACE rollers, refer to page 6.
LOAD CAPACITY
• Insert the Allen wrenche through
the rail attachment hole, into the
socket head of the roller to calibrate,
only the rollers which are
accessable.
• slightly loosen a bit the rollers fixing
screw to enable some pivoting
movement of the screw (not too
much).
• Slightly rotate the roller by means
of the socket head screw in one
direction or, alternatively, in the
other, to “feel” the increase of
clearance or preload. Reach the
position of a clearance. Then turn
the roller against upper raceway to
eliminate the clearance, achieving
a small preload. Subsequently,
tighten the screw again, maintaining
firm the socket head screw behind
the roller;
The preload is set for the slider in
the special raceway it comes with -
To avoid the need of additional
adjustments, keep the sliders and
rail/raceway together.
However in case preload setting or
adjustment is necessary, this is easily
done by turning the rollers with the
eccentric pivot by means of a pair of
Allen wrenches, as shown below.
Manual adjustment of the slider
inserted in the MR-rail:
Tightening torgue of rollers:
RR18 = 3 Nm
RR28 = 9 Nm
RR43 = 22 Nm
• Verify the slider’s running
smoothness along the rail.
• Caution: the slider should move
very easily, but without any
clearance. If the slider moves with
difficulty, it means that the preload
setting is too high and this may
result in a reduced lifetime of the
MR rail.
• In order to obtain precise preload
setting, specific adjustment tools
are available on request. These
tools are special preload
measurement devices, very much
similar to those used during
production. Our Technical
Department is always available for
any further explanation or advice.
For applications with more than 2
rollers in a pair of rails, we
recommend the configuration of
concentric and eccentric rollers as
indicated in figure C.

Sizing control System lifetimeWhen the positioning and configuration
of rails and sliders or rollers is
determined, it is necessary to verify the
correct sizing of system components,
for both static and dynamic function.
With regard to the static verification, it
is necessary to determine the load
applied onto each single slider. When
the heaviest loaded slider is identified,
the safety coefficient must be calculated
on that slider and the result must be
compared with the maximum static load
capacity.
When the load applied is the result of
a sum of radial and axial loads as well
as moments, it is necessary to calculate
the value of each component and verify
the following:
Pax----------Co ax
Prad----------Co rad
Mx----------
Mox
My----------
Moy
Mz----------
Moz
1------
Z+ + + + <=
Where:
• Pax = axial load component;
• Prad = radial load component;
• Mx,My, Mz = applied moments;
• Co ax = axial load capacity
• Co rad = radial load capacity;
• Mox,Moy, Moz = resistance capacity to moments;
• Z = safety coefficient >= 1
1------
Z<=
Pax----------Co ax
Prad----------Co rad
+
For system sizing of FLEXRACE,
only the axial (Pax) and radial (Prad)
load components must be taken into
consideration. As a result, it is
sufficient to calculate the following:
Z
1 - 1,5
1,5 - 2
2 - 3,5
Application conditions
Accurate determination of static and dynamic loads.Precise assembly, tight structure.
Average conditions
Insufficient determination of applied loads.Vibrations, loose structure. Imprecise assembly.Unfavourable environmental conditions.
It is recommended to apply the following values to safety coefficient Z:
The actual lifetime of the system (rails,
sliders, and rollers) depends on the
applied load, but is also influenced by
factors such as: correct lubrification,
environmental conditions, assembly
precision to avoid uncalculated
component stress/wear, total cycle
length.
In order to estimate the expected system
lifetime in km of operation, the following
equation must be solved:
L(Km) = 100 x (C/P)3 x fc/n x fa
Where:
Co= dynamic load coefficient of roller or slider
P = is the equivalent load applied on the heaviest loaded roller or slider.
For each single roller: P = P rad + (Pax / Co ax) x Co rad
For the slider: P = P rad + (Pax / Coax + Mx / Mox + My / Moy + Mz / Moz)
x Co rad
Fc = coefficient depending on the actual length of the stroke. This is an
important factor in the case of applications with short stroke and high
frequency. In these cases total lifetime in km is much shorter, than if application
with long strokes. The factor is equal to 1 for stroke longer than 2 meter,
while for shorter than 2 meter, the value is derived from the graph shown
below:
n = number of rollers or sliders running on the same rail.
fa = coefficient depending on lubrication and environmental conditions;
recommended values are shown in the table below:
fa
0,7 - 1
0,2 - 0,5
0,05 - 0,1
Application conditions
Good lubrication; availability of self-lubricating railwiper system; no dust accumulation and no pollutants;precise assembly.
Random lubrication; environmental dust;thermal fluctuations; vibrations.
Low lubrication; high environmental pollution;strong thermal fluctuations; high vibrations.

Corrosion Resistance All MR and FXR rails have a surface
treatment, which guarantees the
hardness and offers a high resistance
to corrosion. As the surface treatment
is carried out after working the
raceways, the complete surface has
a high corrosion protection also on
the raceways.
The treatment gives the rails an
overall black finish.
In comparison to traditional electrolytic
galvanization zinc plating, this surface
treatment offer a much better corrosion
resistance protection of the rails, which
usually are more exposed to corrosion
than the sliders.
All sliders and intermediate plate in TLR
telescopic rails have an electrolytic zinc
platting surface treatment.
Maintenance The roller’s internal elements are
lubricated and protected by double lip
seals (2RS). As a result, they are
maintenance free.
The sliders of the MONORACE and
TWINRACE systems are equipped with
lateral seals and a system of strong rail
wipers, which incorporate a lubrification
system, assuring a release of lubricating
oil on the raceways overtime. This gives
a maintenance free systemfor the entire
lifetime, under normal clean operational
environment.
A similar rail wiper and lubrification
system is also standard assembled on
the entire system of TELERACE
telescopic rails of the TLR series.
In case the wipers with integrated
lubrication system is disassembled,
it is necessary to provide a periodic
manual lubrication of the raceways,
to assure a sufficient lubrication on
the contact areas. In addition, it is
also necessary to regularly clean the
raceways for impurities or other
residues.
For lubrification we recommend to
apply standard Litium soap
lubrication, specific for ball bearings.

information or questions about their
correct installation, may be requested
to our Technical Department, which
also support with our best technical
dimensioning of any application.
Additional technical information
Linear precision As a result, two slider precision values
are determined, one referring to the
surface the rails is fixed to ( = A ) and
the other ( = B ) to the precision of
supporting rail.
Precision is achieved when the
surfaces are aligned.
When all screws are correctly
tightened, the MR rail aligns with the
fixing surface, and this adds up to
the construction linear precision of
the same rail.
When the MR-rail is loose, it may
result slightly curved. However, this
does not give rise to any problem of
alignment, once the rail is properly
fixed.
T RACE reserves it right to change
data and characteristics in the
catalogue without further notice.
We apologize in case any
errors or omissions
have been made, despite
every care has been taken
in making the catalogue.
The linear precision of the running
slider depends on the rail and,
specifically, on the longitudinal
parallelism between the raceways
and precision of the surface to which
they are mounted.
