Assembling Y-bearings into housings with fitting slots
When mounting a Y-bearing into a housing with fitting slots, the bearing should be inserted into the fitting slot in the housing bore (fig. 1) and then swivelled into position. The misalignment of the bearing relative to the housing should not exceed 5°. Eccentric locking collars should be removed from the bearing prior to mounting and reinstalled when the bearing is in position in the housing.
The locking device should face in the same direction as the fitting slots, except for stainless steel housings and composite housings for SKF Food Line with designation suffix L. When mounting bearings into these housings, the locking device should face in the opposite direction to the fitting slots.
Make sure that no relubrication hole or groove in the bearing outside diameter coincides with either of the fitting slots in the housing, otherwise grease leakage may result or contamination might enter the bearing (fig. 2).
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 (fig. 3).
SKF recommends mounting SKF Y-bearings only into SKF Y-housings to avoid a mismatch of components and to enable proper bearing relubrication.
