SLIDE WAY

The NB slide way NV type comprises precisely ground rails and R-retainers (made of resin) with built-in STUDROLLERs and precision rollers. The rails have been optimally designed so that the STUDROLLERs move smoothly, and the STUDROLLERs in the R-retainers enable slip-free operation between the raceway surface and suitable for the motion of up and down and very fast cycle, which is the weak fi eld for slide way products.

The STUDROLLER system is based on a new concept to provide complete prevention of roller cage slippage during operation. This system permits usage in all orientations and positions.

Non-slip! NV type STUDROLLER System (Rivet Roller Structure)

Suitable for Minute MotionBecause the frictional resistance is extremely small and there is only little difference between the static and dynamic frictional resistances, the NB slide way is well suited for minute motion, resulting in highly accurate linear movement.

Low-Speed StabilitySince the frictional resistance fl uctuation is small even under low-load conditions, stable motion is obtained at from low to high speeds.

High Rigidity and High Load CapacityCompared to the ball elements, the rollers provide a larger contact area and less elastic deformation, thus the NB slide way has high rigidity and high load capacity.With new NV rail design, the roller contact area is increased by 30 to 58% (Figure 1). The number of effective rollers is increased by narrowing the roller pitch. Thus, the NV type has the load rating that is 1.3 to 2.5 times that of the SV type.

Low NoiseThe slide way never produces recirculation noise nor rollercontact noise due to a use of roller cage, resulting in quiet motion.

All Stainless Steel Type AvailableThe anti-corrosion SVS/SVWS/NVS-RNS slide ways have all stainless steel components, making them ideal for use in clean room applications.

The accuracy of the NV type is represented as parallelism measured across the full length with a method shown in Figure 6. It is classifi ed as high (blank), precision (P), or ultra precision (UP). Special accuracies can also be accommodated. Please contact NB for details.

The motion accuracy of NVT and NYT type is measured by placing indicators at the center of the top and side surface of the table, as illustrated in Figure 7. It is expressed in terms of the indicator deviation when the table is moved the full stroke without any load.For accuracy, please see the dimension tables.

The life of the slide way and the slide table is calculated with the following equations:

The load rating of the NV, NVT and NYT type differs depending on the direction of the load.

before installation.

(1) Remove bur r s , sc ra tches , and dus t f rom the railmounting surface of the bed and the table, be careful to prevent contamination during assembly.

(2) Apply low-viscosity oil to the contact surfaces, and align the bed and the table. (Figure 11a)

(3) Set the reference surface onto the mounting surface with the rails fastened. Set the table in the center position, and tighten the adjustment screws lightly so that almost no gap remains. (Figure 11b)

(4) Keep the table in the center, tighten the rail mounting bolts lightly, loosen the end pieces of both ends, and remove the fastening plates. Following this, lightly retighten the end pieces.

(5) While maintaining the conditions of (4), gently move the assembly through its stroke to check if the maximum stroke is secured, and if there is no irregularity.

(6) Move the table to the center and tighten only the ad justment screws on the R- re ta iner w i th the recommended torque shown in Table 2. (Figure 11c)

(7) Gently move the table to one stroke end, and check that the table has surely come into contact with the external mechanical stopper. Following this, tighten the adjustment screws in the same manner as (6). (Figure 11d)

(8) Move the table to the opposite stroke end, and tighten in the same manner as (6). (Figure 11e)

(9) Fasten the mounting screws on rails 1, 2, and 3 by tightening with the recommended torque shown in Table 3. (Figure 11f)

(10) Set the dial indicators to the center of the table and to the side (reference surface) of the table. (Figure 11g)

(11) Perform the fi nal preload adjustment. While moving the table back and forth, repeat steps (6) to (8) until the dial indicators show a minimum deviation.

(12) Fasten rail 4 securely with the recommended torque. As for the adjustment screws, successively tighten the mounting screws on the R-retainer by moving the table.

(13) Recheck the motion accuracy while moving the table. (14) Tighten the end pieces fi nally.

SPECIAL MOUNTING SCREW BT TYPE

USE AND HANDLING PRECAUTIONS

In case of mounting slide way by screws from the counterbore side, threaded holes become the pilot holes. Thus, pilot hole's clearance will be less than a standard clearance hole for a screw. NB offers reduced shoulder screws for mounting SlideWay from bottom when larger screw clearance is required due to preload adjustment or inaccuracy of mating threaded holes. This special mounting screw made of alloy steel is stocked, and custom stainless steel version is available as a special order. Please contact NB for details.

Careful HandlingDropping the slide way causes the rolling elements to make dents in the raceway surface. This will prevent smooth motion and will also affect accuracy. Be sure to handle the product with care.The NV type is packaged as a set of rails and R-retainers. Do not separate or disassemble until assembly/installation is completed. Precision is not guaranteed if disassembled.

Fastening PlatesFor the NV type, fastening plates are attached at both end faces of the rails to maintain the R-retainer center position prior to assembly. The fastening plates are not required after the NV type is mounted to a table and bed, however, when removal of the NV type is necessary such as when it will be reassembled, be sure to return the R-retainer to the proper center position, secure the fastening plates with the end pieces, and then remove the NV type.

Specifi ed Allowable StrokeFor the NV type, exceeding the specified stroke (overstroke) shall cause the raceway surface of the rail to be damaged and the performance of the STUDROLLER to drastically deteriorate. Be sure to provide external mechanical stoppers.

AdjustmentUsing the product with insufficient accuracy of the mounting surface or before adjusting the preload will cause the motion accuracy of the product to drop and will have a negative influence upon product l i fe and accuracy. Make sure to assemble, install, and adjust the product with care.

Caution against Excess PreloadIt is essential to give preload on the Slide Way products in order to assure rigidity and accuracy.

However, excess preload causes damage on the raceways and roller cages/R-retainers.On installation, please follow the installation procedure and recommended torque on page 3.

Use as a SetThe accuracy of the rails has been matched within each set. Note that the accuracy will be affected when the rails of different sets are combined.

Allowable LoadThe allowable load is a load under which the sum of raceway in the contact area subject to the maximum contact stress is small enough to guarantee smooth rolling movement. When very smooth and highly accurate linear motion is required, make sure to use the product within the allowable load.

StopperEnd pieces are attached to each end of the slide way to prevent removal of the cage. Do not use them as a mechanical stopper.

Operating TemperatureThe NV type uses resin parts. Please use the product in environments that are lower than 80℃.

Dust PreventionDust and foreign particles affect the accuracy and lifetime of the slide way. The slide way used in a harsh environment should be protected with a cover.

LubricationThe slide way is prelubricated with lithium soap based grease No. 00 prior to shipment for immediate use. Make sure to relubricate with a similar type of grease periodically depending on the operating conditions. NB provides low dust generation greases for your linear system.
