This insert ball bearing carries a rubber interliner between the outer ring and the bearing insert, which compensates for shaft misalignment and absorbs shock loads. The unit is located on the shaft by an eccentric locking collar and is sealed on both sides with P seals. Bore diameter is 15.0 mm, outside diameter 47.3 mm, and net mass 0.2 kg. The rubber interliner allows the inner insert to self-align within the outer ring, so the bearing tolerates a degree of shaft deflection without inducing additional stress on the balls and races. The eccentric locking collar provides secure axial fixation on the shaft without requiring a separate fastening element, simplifying mounting and dismounting. The P seals on both sides restrict the ingress of dust and moisture into the bearing interior, helping retain the internal grease charge and maintaining consistent running conditions.
