This insert ball bearing carries radial loads through a spherical outer ring surface seated in a cylindrical housing, with the outer ring featuring slots and secured to the shaft by an eccentric locking collar. Bore diameter is 40.0 mm, outside diameter 80.0 mm, width 30.2 mm, and net mass 0.65 kg. Sealing is of the NPP type, with P seals fitted on both sides of the bearing. The eccentric locking collar allows quick mounting and secure fixation on the shaft without additional fasteners, while the slots in the outer ring support the locating function within the housing. The NPP sealing arrangement protects the internal raceway and rolling elements from dust and moisture ingress, reducing the need for frequent relubrication. The spherical outer ring surface permits a degree of shaft misalignment relative to the housing, which is useful where slight angular deviation between shaft and support cannot be avoided.
