This insert ball bearing carries radial loads through a spherical outer ring, which seats in a housing and allows the bearing to self-align during mounting. The inner ring is fixed on the shaft by grub screws, giving a secure axial location without additional clamping parts. Bore diameter is 90.0 mm, outside diameter 160.0 mm, width 96.0 mm, and net mass is 3.73 kg. Sealing is provided by KRR seals fitted on both sides of the bearing. The spherical outer ring surface compensates for slight misalignment between the housing bore and the shaft, easing installation and reducing edge loading on the ball track. The KRR seals close off the bearing on both faces, keeping grease in and contaminants out, so the unit can run with the grease fill already provided without frequent relubrication. The grub-screw fixation suits applications where the shaft sees moderate speed and where a simple, serviceable locking method is preferred over a locking collar.
