NOTICE
• These bearings are designed for maximum permissible
static misalignment of ± 2 degrees. Installation, handling
or operation of the bearing in excess of the maximum of ±
2 degrees can cause reduction in bearing performance and
may lead to equipment failure.
• Do not strike or hammer on any component of the bearing
and/or shaft. Impact can result in damage to the bearing
that may cause reduction in bearing performance and may
lead to equipment failure.
Step 1: Inspect Shaft and Bore
Shaft should be within tolerance range shown in table, clean
and free of nicks and burrs. Mount bearings on unused
section of shafting or repair/replace shafting as required. In-
spect both the shaft and bearing bore for debris or contami-
nants. Wipe clean as necessary.
Step 2: Check Support Surfaces
Make sure the base of the housing and the support surfaces
are clean and free from burrs. If the housing elevation is
adjusted with shims these must cover the entire contact area
between the housing and the support surface.
Step 3: Install Unit
To aid installation, keep weight off bearing during mounting.
Slide unit onto shaft by pushing on the inner ring. If it is dif-
cult to mount bearing on shaft, use a piece of emery cloth
to reduce any high spots on the shaft.
Step 4: Fasten Unit in Place
Install housing mounting bolts and check bearing alignment.
Align the bearing units as closely as possible. Tighten mount-
ing bolts to recommended fastener torques. Check the shaft
for freedom of rotation by rotating shaft with hand in both
directions.
Step 5: Position Insert
If expansion units are used, the insert must be located in the
housing to allow for axial shaft expansion and/or contrac-
tion. Position bearing insert to obtain the required axial ex-
pansion in desired directions. It may be necessary to unload
the bearing while moving the assembly.
