Axis Angular Contact Ball Bearings Brochure

Introduction
Deep Groove Ball Bearings
At Axis, we build exceptionally close 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 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.

Ball Bearings
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°

Ball Bearings
7300 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.

Angular Contact Installation
Orientation of Angular Contact Pairs
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.
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.
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

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.

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
High pitch, steady tone
Low pitch continouous or
intermittent
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.
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
Bearing brinelled (indents in bearing)
Replace bearing, avoid brinelling.
Raceways pitted due to dirt
Wash 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.
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.
To much clearance 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.
Dirt in bearing
Wash all parts, replace with new bearing, use clean lubricant,
improve sealing.
Loose machine parts
Tighten all fans, pulleys, closures, spacers, slingers etc.
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.
Excessive axial load
Check outer ring fit in housing and/or shoulder location to
allow thermal expansion.
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 loading.
Bearing misalignment
Correct machine parts and alignment procedures.
Excessive seal drag
Use different type of seal or shield.
NOISE
Intermittent squeal or high
pitch noise
Intermittent rumbles, rattles
clicks, etc.
High after first start
TEMPERATURE
54
Continuously high during
operation

Bearing Troubleshooting
Trouble
Observed Characteristic
During acceleration or
deceleration periods
EXCESSIVE
VIBRATION
RUNOUT
OUTER RING
WEARS LOOSE IN
HOUSING
During operation at fixed
speeds
Shaft does not run true.
Shaft binds when rotated
by hand.
Probable Cause
Corrective Action
Critical speeds of machine components
Stiffen shaft or other machine components to avoid critical
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.
Shaft bent
Straighten and re-balance, or replace shaft.
Bearing misalignment
Correct machine parts and alignment procedures.
Bearing rings out of square
Check squareness of shaft and housing shoulders, spacers
and flingers. Remove any burrs.
Dirt
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.
Unbalanced forces
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.
Poor finish
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.
Wear in housing bore
