This insert ball bearing carries a spherical outer ring and is secured on the shaft by grub screws, allowing quick radial mounting without a separate adapter sleeve. Bore diameter is 12.0 mm, outside diameter 47.0 mm, width 31.0 mm, and net mass 193.0 g. Sealing is provided on both sides by 2RSR seals, protecting the internal raceway and balls from dust and moisture ingress. The spherical outer ring seated in a matching housing allows the bearing to self-align, compensating for slight shaft misalignment during operation. Grub screw fixation gives a simple and reliable axial and rotational lock on the shaft without requiring precision fitting. The double-sided 2RSR sealing retains factory grease and reduces the need for frequent relubrication, making this insert ball bearing suitable for mounting in pillow block or flanged housing units where straightforward assembly and low maintenance are required.
