This insert ball bearing carries a rubber interliner between the inner ring and shaft, compensating for shaft tolerance and reducing fretting at the seat. Locking onto the shaft is achieved through an eccentric locking collar, and P seals are fitted on both sides to keep grease in and contaminants out. Bore diameter is 15.0 mm, outside diameter 65.1 mm, net mass 0.195 kg. The rubber interliner allows a firm grip on the shaft without the precision fit required by set screw or adapter sleeve designs, so shaft machining tolerances can be looser. The eccentric locking collar gives a simple, tool-free mounting and dismounting procedure once the correct rotation direction for locking is respected. Double-sided P seals provide protection against dust and moisture ingress, supporting grease retention over extended running periods without frequent relubrication.
