The bearings installed in different bearing housings are 162362562 and 762.2rsr series deep groove ball bearings. The first three series bearings have a widened inner ring. They can be fixed to the shaft by eccentric locking rings (162 and 362 Series) or by two upper screws (562 Series). Oil rejection in 362 and 562 series bearings protects the bearings from large particle contamination.
