Description

This insert ball bearing carries a spherical outer ring, allowing it to be mounted in a housing while accommodating shaft misalignment. Bore diameter is 55.0 mm, outside diameter 100.0 mm, width 32.5 mm, and net mass 1.06 kg. The design corresponds to the XL series with reinforced load ratings. Sealing is of the NPP type, providing contact seals on both sides to protect the raceway and balls from contamination and to retain the grease fill. The self-aligning outer ring geometry compensates for shaft deflection and housing misalignment, simplifying installation without requiring precise shaft-to-housing alignment. The NPP sealing arrangement allows operation without additional external sealing measures, while the balance of internal clearance suits standard shaft fits typical for insert bearing applications with a locking mechanism corresponding to the B suffix.
