This insert ball bearing has a spherical outer ring, allowing it to self-align within a housing and compensate for shaft misalignment. It is designed as a non-locating bearing and features a drive slot in the inner ring for torque transmission via a locking mechanism engaging the shaft. Bore diameter is 40.0 mm, outside diameter 80.0 mm, and width 42.9 mm, with a net mass of 0.56 kg. The bearing is sealed on both sides with R-type seals (KRR), providing protection against dust and moisture ingress while retaining grease within the bearing. The spherical outer ring geometry permits mounting where slight angular deviation between shaft and housing bore exists, making this design suitable for applications requiring a non-locating position on the shaft combined with reliable sealing and simplified torque transfer through the drive slot.
