INSTALLATION OF BEARINGS FITTED
WITH BUSHINGS
1. The shaft journal surface must be equal to that of commercial
steel shafting (about 32 micro inches), without nicks and
burrs and the shaft diameter within the tolerance of +0.000/-
0.002. The shaft must be straight.
2. Position bearing, when possible, so that grease groove is
opposite to most heavily loaded surface of bearing bore.
Direction of load should not be closer than 30 degrees to
grease grove or closer than 30 degrees to the joint between

replacement if wear should make that necessary. Clean shaft and bore of bearing. Coat bore with grease.
CAUTION: Rust preventatives and solvents can be
toxic and/or flammable. Follow directions and safety
procedures recommended by their manufacturers.
4. Assemble bearing on shaft. Reinstall brass locking spool
before replacing cap on base. Torque cap bolts to value listed
in table(s).
5. Line up bearings accurately with shaft by using a feeler gage
or shim stock. This will ensure clearances at the joints are
equal at all four corners. Torque bearing mounting bolts to
value given in table(s). Maintain proper bearing alignment for
uniform distribution of load under all operating conditions.
6. Ambient temperature should not exceed 300°F. If the shaft
transmits heat from a source such as an oven, the shaft
temperature at the bearing should not exceed 300°F.
7. Bearings should be protected against adverse operating
conditions.
8. Normal running loads must not exceed ratings shown in load
tables (see catalog). Starting and occasional peak loads

without moving shaft from bearing base or moving base from
its support. The following instructions show how this can be
accomplished.
1. Remove bearing cap and brass locking spool. Wipe grease
and dirt from cap, base and shaft so that replacement
bushings can be installed properly. Raise shaft slightly. Pry
bushing loose from base as illustrated. Also pry bushing
loose from cap.
5. Lower the shaft. Put brass locking spool in place. This
prevents all movement of bushings. Apply grease to bore of
cap bushing. Install cap on base with notch in cap fitting over
the locking spool. Torque cap bolts to value given in table (s).
Bushing will seat when cap is bolted down.
2. Hold base bushing against shaft, rotate bushing and remove.
Make sure that the housing base is free of dirt. Apply grease
to bore of replacement base bushing (without grease groove)
and roll in place, positioning notch for locking spool with
notch in base.
3. Center the bushing lengthwise in the bearing base. Tap into
position, being careful not to damage the bushing.
