Component assignment
When dismantling or assembling the bearing pay attention to the proper arrangement of the
components particularly if the bearing is the same size on the DE side and NDE side, for

● Bearing shield
● Bearings
● Compression springs
● Spacer washers,
● Covers with different centering length, etc.
