This insert ball bearing carries a spherical outer ring and is located on the shaft by grub screws, allowing radial load transfer with self-aligning contact against the housing bore. Bore diameter is 25.0 mm, outside diameter 52.0 mm, width 27.0 mm, and net mass is 0.15 kg. The design corresponds to the GAY25-XL-NPP-B execution. Sealing on both sides is of the NPP type (P seals), protecting the raceway and grub screw fixing from dust and moisture ingress during operation. The spherical outer ring surface permits a degree of self-alignment within the housing, compensating for minor shaft misalignment, while the grub screw fixing provides a fast, tool-based method of securing the inner ring to the shaft without additional locking elements.
