Deep Groove Ball BearingsAt Axis, we build exceptionally close tolerances into our bearings. Instead of the usual ABEC 1, we manufacture ev-

ery Axis bearing to meet or exceed ABEC 3 tolerances. We use grade 10 balls, normally found in ABEC 5 (or better),

instead of grade 25. This insures a rounder, more precise diameter ball and gives longer life because the balls share

the load evenly. All Axis deep groove ball bearings are noise and vibration tested. We use Polyrex EM grease that

has become the lubricant of choice for the electric motor industry. In addition, we use high strength, temperature

resistant steel as standard in our retainers. All of these features add up to longer life.

Angular Contact Ball BearingsAll Axis angular contact ball bearings meet or exceed ABEC 5 tolerances. They feature forged rings for superior

grain structure. The machined bronze retainer provides superior strength and heat dissipation. They come with a

40-degree contact angle for high thrust load capacity. All Axis angular contact ball bearings are universally flush

ground allowing them to be paired in any configuration your application demands.

B = 40° contact angle

Contact Angle (a) – the angle between the radial plane and a line join-ing the two contact points of the inner and outer race.

Angular contact bearings have races with high shoulders allowing the balls to operate at higher contact angles giving them increased one di-rectional thrust capacity over the same size conrad style (deep groove) bearing. Greater clearances between the balls and the raceways allows for higher contact angles.

Standard contact angles: B – 40° C – 15°

B = 40° contact angle

Contact Angle (a) – the angle between the radial plane and a line joining the two contact points of the inner and outer race.

Angular contact bearings have races with high shoulders allowing the balls to operate at higher contact angles giving them increased one directional thrust capacity over the same size conrad style (deep groove) bearing. Greater clearances between the balls and the raceways allows for higher contact angles.

Standard contact angles: B – 40° C – 15°

Radial Internal Clearance

Tolerances for Single-Row Ball Bearings

Listed in ten-thousandths inches (.0001”) and micrometers (µm).

Radial Internal Clearance is the average of the radial distances through which one of the rings (of a non-preloaded

bearing) may be displaced relative to the other.

General Bearing InstallationENGINEERING SECTION

Shaft ConditionCheck shaft total indicated run-out (TIR), dimension of the bearing fit and the condition of the bearing mounting surface and shaft shoulder. The TIR should be less than 0.001” [0.025mm] at the journals with the shaft running in its shaft centers or on roller steady rests in a lathe.

The shaft journal diameter is critical due to its effect on the internal clearances of the bearing. With inner ring rotation (motors, pumps, etc.) there is an interference fit between the shaft journal and bearing inner ring that will cause the inner ring to expand when it is installed on the shaft. It is important to have shaft journals that are within the tolerances specified by the equipment manufacturer. A fit that is too loose or tight will make a big difference in bearing life. If shaft fits aren’t available from the equipment manufac-turer, use the chart on page 44 to determine the proper shaft fit for your application.

CleanlinessAny foreign material that gets into the bearing will result in damage to the rolling elements and rings and a shortened bearing life. Bearings should never be removed from their original packaging until ready for use. They should be handled as little as possible, and should be kept away from dirty areas. Inspect the bearings being used for correct bearing number, damage, rust stains, or metal debris prior to installation.

Proper HeatingHeating is by far the best method for proper bearing installation. Heating must be done evenly, using an induc-tion heater, oven, or some other device for heating the bearing evenly without damage. Flame heating should never be done because it generates localized tempera-tures that permanently affect the metallurgical properties of the bearing.

The proper temperature for heating a bearing is between 65 C – 120 C (150 F – 250 F). Under no circumstances should the high temperature limit be exceeded. We typically recommend 104 C (220 F) as a target temperature. Measure the temperature on the inner ring using a calibrated temperature stick, or thermocouple.

After proper heating, the installation should be executed crisply. The inner ring temperature lowers very quickly once it contacts the shaft. Once the bearing is on the shaft, hold it at the inner rings against the shaft shoulder for about 30 seconds or until the inner ring has cooled and shrunk. (This prevents it from moving away from the shaft shoulder while it is still hot.

ENGINEERING SECTION

Angular Contact InstallationOrientation of Angular Contact Pairs

Angular contact thrust bearings typically have a contact angle of between 15 and 40 de-grees. The contact angle is determined by the looseness in the bearing. A looser fit between the ball and raceways allows the ball to run farther up on the shoulder, which increases the contact angle.

Angular contact thrust bearings can be paired together in three arrangements: tandem, face-to-face or back-to-back. The tandem ar-rangement increases the thrust capacity in one direction but has no provision for thrust in the opposite direction. Back-to-back or face-to-face pairing of two angular contact bearings provides bi-directional thrust capability. The back-to-back arrangement is the most com-mon configuration.

While both arrangements give equal thrust capacity, the back-to-back arrangement gives more shaft rigidity and the face-to-face ar-rangement gives more shaft flexibility.

If possible, install the bearings together, slid-ing them onto the shaft until they seat against the shaft shoulder. If properly heated, the bearings will slide easily. If the bearings are too large to safely handle as a pair, install them one at a time, seating the first bearing against the shaft shoulder, and the second bearing against the first bearing.

Proper TighteningNote: Ring length tolerances can be held so that when the bearings are clamped together, slight axial play exists. For most applications this is desirable (UA suffix). For some applications, no axial play is desirable (UO suffix). For applications where extreme shaft rigidity is desired, ring lengths that preload the assembly can be used.

Tighten the locknut hand-tight. In order to protect the key of the washer from shearing, the lock-washer should not be used at this time. Make sure that the tapered O.D. portion of the locknut is toward the bearing. This keeps any deformation of the slots away from the bearing (deformation of the slots due to improper installation of the locknut can cause the bearing’s ring to become cocked on the shaft). Once the locknut is hand-tight, wait about a minute for the shaft to pick up heat from the bearing; then, using a spanner wrench and hammer, drive the locknut tight. “Tight” is defined as a distinct feel that the inner rings of the bearing are seated together and the locknut will start to distort if driven tighter. Wait about 10 minutes and re-tighten a second time. While the bearings are cooling, use clean lint-free rags, or oil paper, to cover and protect the bearings from foreign matter contamina-tion.

Note: Use of steel or brass drifts can cause metal flakes to be dislodged and enter the bearing. Steel or brass drifts may also lead to further deformation of the slots, which can lead to a cocked/tilted rings. Use of a proper spanner wrench is strongly recommended.

To check installation, after bearings and shaft are cooled, remove the locknut. Spin the outer rings of the bearing. Try to rotate one outer ring CW while trying to rotate the other outer ring CCW. This should be difficult with a normal clearance (UA suffix) designation and not possible with a preloaded bearing. Depending on the preload, the bearings should now turn, in the same direction, freely, or with slight resistance. The resistance to turning the bearing should be consistent through 360 de-grees of rotation. Inconsistent resistance to rotation is an indication of an incorrectly mounted bear-ing, or a sign of foreign material in the bearing. If you can not get the bearings to spin with consistent resistance, remove the bearings to investigate. Do not proceed!

If a bearing must be removed from the shaft, it is generally best to replace it. Whenever a bearing is removed from the shaft, there is a risk of damage to the rolling elements and rings. The cost of a new bearing is a fraction of the cost of a pump or motor that goes out of service prematurely. If the installed bearings spin properly, install a new locknut and lock-washer and tighten. Then bend a tang on the lockwasher into one of the notches on the OD of the locknut.

With cleanliness in mind, hand pack the bearings with appropriate grease if it is grease lubricated (20-30% fill is typically recommended). If it is oil lubricated, oil the bearing down with the correct clean oil. Install the housings, covers, seals and slingers to complete rotating element assembly and protect the bearing.

End Play RequirementsAxis 7000 angular contact ball bearings are built to take one directional thrust loading when individu-ally mounted. Additional one directional capacity or the ability to take reversing thrust loads can be accomplished by duplexing the bearings (see page 39).

Duplexing requires a controlled relationship between the axial location of the inner and outer ring faces. This process is known as flush grinding.

The suffix UA is used to describe bearings that will have slight axial clearance when the bearings are used in any of the 3 duplex mounting configurations. See chart on this page for the amount of unmounted axial clearance. The U stands for “U”niversal mounting meaning that these are flush ground to give this axial clearance in any of the 3 mounting configurations. The A stands for slight “A”xial end play.

Bearings with a U0 suffix will have zero end play when duplexed. Preloaded pairs can also be supplied.

Make sure after assembly that your equipment does not have more play than the Max and / or less play then the minimum. Either of these condi-tions is due to a looseness or tightness in the fitting of the bearings.

Preload offset(Before clamping inners)

(Back to Back)

Axis spindle pairs are produced with a specific preload when clamped together. The relationship of the inner and outer ring face widths is controlled to cause an elastic deformation to occur when this clamping takes place. This eliminates shaft deflection.

These preloads are small in comparison to the capacity of the bearing pair. The preloads are found in this chart.

The light preload is standard, although medium and heavy preload are available upon request.

Shaft FitsThe table on page 44 outlines an approach to shaft fit selection based on factors such as load condi-tions, rotational conditions, and bearing size. Note that for general applications involving inner ring rotation and a constant radial load, an interference fit is recommended. The interference should be greater for heavier loads. For stationary shaft conditions, where the direction of radial load is constant, a moderate clearance fit is acceptable. The tables on page 46 & 47 contain numerical values for the various tolerance classifications.

Housing FitsThe table on page 45 outlines an approach to housing fit selection. Note that the use of clearance or interference fits is primarily based upon which bearing ring rotates in relation to the radial load. The extent of the radial load also influences the choice of fit. For indeterminate or varying load directions, clearance fits should be avoided. Clearance fits should be chosen for axially split housings to avoid distorting bearing outer rings. The tables on page 48 & 49 contain numerical values for the various tolerance classifications.

Trouble Observed Characteristic Probable Causes Corrective Action

NOISE

High pitch, steady tone

Excessive axial loadCorrect outer ring fit in housing and/or shoulder location to allow thermal expansion. Look to reduce axial loading.

Excessive radial loadUse correct fit of inner ring on shaft. For radial bearings, use bearing with greater internal clearance. For preloaded paired bearings, use lighter preload. Look to reduce axial loading.

Misalignment Correct alignment

Low pitch continouous or intermittent

Too much clearance in bearingUse correct shaft fit. For radial bearings use bearing with less internal clearance. For preloaded paired bearings, use heavier preload

Bearing brinelled (indents in bearing) Replace bearing, avoid brinelling.

Raceways pitted due to dirtWash all parts, replace with new bearing, use clean lubricant, improve sealing.

Resonant vibration of machine structure

Stiffen or sound-deaden thin panels and large flat surfaces.

Intermittent squeal or high pitch noise

Ball skiddingProvide thrust preload spring. Use thinner grease. For radial bearings, use bearing with less internal clearance. For pre-loaded paired bearings, check for correct preload.

Shaft rubbing housing Correct machine fits. Eliminate looseness.

Intermittent rumbles, rattles clicks, etc.

To much clearance in bearingCorrect shaft fit. For radial bearings use adjusting spring or bearing with less internal clearance. For preloaded paired bearings, check for correct preload.

Dirt in bearingWash all parts, replace with new bearing, use clean lubricant, improve sealing.

Loose machine parts Tighten all fans, pulleys, closures, spacers, slingers etc.

TEMPERATURE

High after first start Grease redistribution Allow machine to cool. Restart slowly if possible.

Continuously high during operation

Churing of lubricant Use lower oil level; less grease; stiffer grease

No lubricant Add lubricant.

Excessive axial loadCheck outer ring fit in housing and/or shoulder location to allow thermal expansion.

Excessive radial loadUse correct fit of inner ring on shaft. For radial bearings, use bearing with greater internal clearance. For preloaded paired bearings, use lighter preload. Look to reduce loading.

Bearing misalignment Correct machine parts and alignment procedures.

Excessive seal drag Use different type of seal or shield.

EXCESSIVE VIBRATION

During acceleration or deceleration periods

Critical speeds of machine compo-nents

Stiffen shaft or other machine components to avoid critical speeds.

During operation at fixed speeds

Unbalanced rotating parts Dynamically balance rotating parts.

Shaft bent Straighten and re-balance, or replace shaft.

Cams, gears, linkage looseness Adjust, improve or redesign.

Misalignment Correct machine parts and alignment procedures.

Bearing brinelling Replace bearing, avoid brinelling.

RUNOUTShaft does not run true. Shaft binds when rotated by hand.

Shaft bent Straighten and re-balance, or replace shaft.

Bearing misalignment Correct machine parts and alignment procedures.

Bearing rings out of squareCheck squareness of shaft and housing shoulders, spacers and flingers. Remove any burrs.

DirtWash all parts, replace with new bearing if necessary, use clean lubricant, improve sealing.

Machine Deflection Stiffen machine members.

OUTER RING WEARS LOOSE IN HOUSING

Wear in housing bore

Housing fit too loose Use recommended housing fit.

Unbalanced forcesDynamically balance rotating parts. Clamp outer ring faces. Use cylindrical roller bearing and press fit outer and inner rings. Use tighter fits on housing to prevent wear.

Poor finishBore or grind housing I.D. oversize, press in a bushing and finish bore or grind to size.

Soft housing material Use steel liners. Work-harden bore.
