Description
This insert ball bearing carries a spherical outer ring and is secured on the shaft by grub screws, allowing simple radial mounting without additional locking elements. Bore diameter is 20.0 mm, outside diameter 47.0 mm, width 25.0 mm, and net mass 0.13 kg. The spherical outer race supports self-alignment within the housing seat, compensating for minor shaft misalignment. Sealing is provided by P-type seals fitted on both sides (NPP), protecting the raceway and balls from dust and moisture ingress while retaining internal grease lubrication. The grub screw location makes mounting and dismounting straightforward without requiring an adapter sleeve, and the design suits applications where the shaft experiences slight deflection or angular offset under load.
