When mounting an insert bearing into a
housing with itting slots, the bearing should
be inserted into the itting slot in the housing
bore (ig. 33) and then swivelled into position

Make sure that no relubrication hole or
groove in the bearing outside diameter

Assembling a bearing into a housing with the housing, otherwise grease leakage may
itting slots result or contamination might enter the
bearing (ig. 34)
If the bearing has to be relubricated, make
sure the relubrication features in the outer
ring (hole, or groove and hole) coincide with
the relubrication feature in the housing bore
The misalignment of the bearing relative to
the housing should not exceed 2°, otherwise
relubrication will not be possible (ig. 35)
SKF recommends mounting SKF insert
bearings only into SKF housings to avoid a
mismatch of components and to enable
proper bearing relubrication
