Description
This insert ball bearing carries a spherical outer ring and is located on the shaft by grub screws, allowing quick radial mounting without an adapter sleeve. Bore diameter is 20.0 mm, outside diameter 47.0 mm, width 25.0 mm, and net mass 0.13 kg. Sealing is of the NPP type, fitted on both sides of the bearing. The spherical outer ring surface permits the bearing to self-align within its housing, compensating for minor misalignment between the shaft and the support. The NPP seals on both sides protect the internal raceway and rolling elements against dust and moisture ingress, keeping the grease fill in place during operation. Grub screw location makes the bearing suitable for shaft mounting where the housing does not need to be split, giving a compact and serviceable radial support point.
