This insert ball bearing carries a spherical outer ring housed in an eccentric locking collar, allowing the inner ring to be secured directly onto the shaft without an additional adapter sleeve. Bore diameter is 20.0 mm, outside diameter 42.0 mm, width 16.7 mm, and net mass is 0.1 kg. Sealing is of the NPP type, fitted on both sides of the bearing (P seals). The spherical outer ring combined with the housing allows the bearing to accommodate shaft misalignment during operation. The eccentric locking collar provides a simple and secure method of axial fixation on the shaft, tightened in the direction of rotation. The NPP seals on both sides protect the bearing interior from contamination and retain grease, making relubrication intervals less frequent under normal operating conditions.
