This insert ball bearing carries a spherical outer ring surface, allowing it to self-align within a housing and compensate for shaft misalignment. Bore diameter is 40.0 mm, outside diameter 80.0 mm, width 30.2 mm, and net mass is 0.606 kg. The extended inner ring design (XL) accommodates a locking element on the bore, transmitting torque between shaft and inner ring without a separate fit tolerance requirement. Sealing type NPP provides contact seals on both sides, protecting the rolling elements from contamination and retaining the grease fill over the bearing's service life. The self-aligning outer ring makes this bearing suitable for shaft arrangements where slight angular deviation must be absorbed without inducing edge loading on the balls, and the sealed design permits operation without additional external sealing arrangements.
