This insert ball bearing has a spherical outer ring that seats in a mating housing, with shaft location secured by an eccentric locking collar. Bore diameter is 25.0 mm, outside diameter 52.0 mm, width 34.9 mm, and net mass is 0.25 kg. The bearing is fitted with KLL seals on both sides, integrated into the outer ring. The spherical outer ring allows the bearing to self-align within its housing, compensating for minor angular misalignment between shaft and housing bore. The eccentric locking collar provides a simple, tool-free method of clamping the inner ring to the shaft, suitable for applications with rotation in a defined direction consistent with the collar's locking action. The KLL seal design on both sides protects the internal raceway and grease fill from dust and moisture ingress, supporting maintenance-reduced operation once initially lubricated.
