This insert ball bearing carries a cylindrical bore of 50.0 mm and an outside diameter of 90.0 mm, with a width of 30.2 mm and a net mass of 0.77 kg. The spherical outer ring profile allows the bearing to self-align in its housing, compensating for shaft misalignment during operation. Sealing is designated NPP, providing contact seals on both sides to retain grease lubrication and restrict the ingress of contaminants. The self-aligning outer ring makes this bearing suitable for shaft arrangements where slight angular misalignment must be accommodated without loss of running accuracy. The NPP sealing arrangement supports grease-lubricated operation with reduced maintenance requirements, as the double-sided seals protect the internal raceway and rolling elements from dust and moisture ingress. Symbol GRAE50-NPP-B-FA106 identifies this bearing for mounting on a 50.0 mm shaft in applications requiring self-alignment combined with sealed, low-maintenance grease lubrication.
