Introduction 

Deep Groove Ball Bearings 

At Axis, we build exceptional tolerances into our bearings. Instead of the usual ABEC 1, we manufacture every 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 Bearings 

All Axis angular contact ball bearings meet or exceed ABEC 5 tolerances. They feature forged steel 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.

7200 Series – Angular Contact 

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°

General Bearing Installation 

Shaft Condition 

Check 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 manufacturer, 

use the chart on page 44 to determine the proper shaft fit for your application. 

Cleanliness 

Any 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 Heating 

Heating is by far the best method for proper bearing 

installation. Heating must be done evenly, using an induction 

heater, oven, or some other device for heating the 

bearing evenly without damage. Flame heating should 

never be done because it generates localized temperatures 

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.

Orientation of Angular Contact Pairs 


Angular Contact Installation 

Angular contact thrust bearings typically have 

a contact angle of between 15 and 40 degrees. 

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. 

A 

n D 

B1 

n d 

Angular contact thrust bearings can be paired 

together in three arrangements: tandem, 

face-to-face or back-to-back. The tandem arrangement 

increases the thrust capacity in one 

direction but has no provision for thrust in the 

opposite direction. Back-to-back or face-toface 

pairing of two angular contact bearings 

provides bi-directional thrust capability. The 

back-to-back arrangement is the most common 

configuration.

n D 

Back-to-Back 

B1 

n d 

While both arrangements give equal thrust 

capacity, the back-to-back arrangement gives 

more shaft rigidity and the face-to-face arrangement 

gives more shaft flexibility. 

If possible, install the bearings together, sliding 

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.

Angular Contact Installation 

Proper Tightening 

Note: 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 lockwasher 

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 contamination. 

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 degrees 

of rotation. Inconsistent resistance to rotation is an indication of an incorrectly mounted bearing, 

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.

Angular Contact Pairs End Play 

End Play Requirements 

Axis 7000 angular contact ball bearings are built to take one directional thrust loading when individually 

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 conditions 

is due to a looseness or tightness 

in the fitting of the bearings.

Preloaded Spindle Sets 

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.

DMP Outer Ring O.D. Tolerance Range 

dmp Inner Ring Bore Tolerance Range 

Clearance Fit – A fit that always enables a clearance between the bearing bore and shaft; or bearing outer 

ring and housing. 

Transition Fit – A fit where both clearance or interference may occur depending on the actual sizes of the 

bearing bore and shaft; or bearing outer ring and housing. 

Interference Fit – This fit always ensures some interference between the bearing bore and the shaft; or 

bearing outer ring and housing. 

Shaft Fits 

The table on page 44 outlines an approach to shaft fit selection based on factors such as load conditions, 

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 Fits 

The 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.

Bearing Troubleshooting 

Trouble Observed Characteristic Probable Causes Corrective Action 

Excessive axial load 

Correct outer ring fit in housing and/or shoulder location to 

allow thermal expansion. Look to reduce axial loading. 

High pitch, steady tone 

Excessive radial load 

Use 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 

Too much clearance in bearing 

Use correct shaft fit. For radial bearings use bearing with less 

internal clearance. For preloaded paired bearings, use heavier 

preload 

NOISE 

Low pitch continouous or 

intermittent 

Bearing brinelled (indents in bearing) 

Raceways pitted due to dirt 

Resonant vibration of machine 

structure 

Replace bearing, avoid brinelling. 

Wash all parts, replace with new bearing, use clean lubricant, 

improve sealing. 

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

Intermittent squeal or high 

pitch noise 

Ball skidding 

Provide thrust preload spring. Use thinner grease. For radial 

bearings, use bearing with less internal clearance. For preloaded 

paired bearings, check for correct preload. 

Shaft rubbing housing 

Correct machine fits. Eliminate looseness. 

Intermittent rumbles, rattles 

clicks, etc. 

To much clearance in bearing 

Dirt in bearing 

Correct shaft fit. For radial bearings use adjusting spring or 

bearing with less internal clearance. For preloaded paired 

bearings, check for correct preload. 

Wash all parts, replace with new bearing, use clean lubricant, 

improve sealing. 

Loose machine parts 

Tighten all fans, pulleys, closures, spacers, slingers etc. 

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

Churing of lubricant 

Use lower oil level; less grease; stiffer grease 

No lubricant 

Add lubricant. 

TEMPERATURE 

Continuously high during 

operation 

Excessive axial load 

Excessive radial load 

Check outer ring fit in housing and/or shoulder location to 

allow thermal expansion. 

Use 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.

Bearing Troubleshooting 

Trouble Observed Characteristic Probable Cause Corrective Action 

During acceleration or 

deceleration periods 

Critical speeds of machine components 

Stiffen shaft or other machine components to avoid critical 

speeds. 

Unbalanced rotating parts 

Dynamically balance rotating parts. 

EXCESSIVE 

VIBRATION 

During operation at fixed 

speeds 

Shaft bent 

Cams, gears, linkage looseness 

Straighten and re-balance, or replace shaft. 

Adjust, improve or redesign. 

Misalignment 


Bearing brinelling 

Replace bearing, avoid brinelling. 

Shaft bent 

Straighten and re-balance, or replace shaft. 

Bearing misalignment 


RUNOUT 

Shaft does not run true. 

Shaft binds when rotated 

by hand. 

Bearing rings out of square 

Dirt 

Check squareness of shaft and housing shoulders, spacers 

and flingers. Remove any burrs. 

Wash all parts, replace with new bearing if necessary, use 

clean lubricant, improve sealing. 

Machine Deflection 

Stiffen machine members. 

Housing fit too loose 

Use recommended housing fit. 

OUTER RING 

WEARS LOOSE IN 

HOUSING 

Wear in housing bore 

Unbalanced forces 

Poor finish 

Dynamically 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. 

Bore 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.
