This insert ball bearing carries a spherical outer ring surface, allowing it to self-align within a housing and accommodate shaft misalignment during operation. The bore diameter is 30.0 mm, outside diameter 80.0 mm, width 30.1 mm, and net mass 0.6 kg. Sealing is designated NPP, meaning the bearing is fitted with contact seals on both sides to keep contaminants out and retain grease inside. The NPP sealing arrangement makes this insert ball bearing suitable for mounting where relubrication access is limited, since the seals maintain the initial grease fill and reduce the ingress of dust and moisture. The spherical outer ring works together with a locking element on the inner ring to secure axial positioning on the shaft, compensating for slight shaft deflection or housing misalignment without loading the balls unevenly.
