This insert ball bearing carries a spherical outer ring surface, allowing it to self-align within a mating housing and accommodate shaft misalignment during operation. The bore diameter is 50.0 mm, outside diameter 90.0 mm, width 30.2 mm, and net mass 0.77 kg. Sealing is designated NPP, providing contact protection on both sides against dust and contaminants while retaining grease within the bearing. The self-aligning outer ring compensates for angular misalignment between shaft and housing, reducing sensitivity to mounting inaccuracies. The NPP sealing arrangement supports grease-lubricated operation with reduced maintenance requirements, making the bearing suitable for applications where shaft deflection or housing bore misalignment must be tolerated without introducing additional stress on the rolling elements.
