Carries radial loads and moderate axial loads in a compact single-row deep groove ball bearing design, generation C, with a bore of 40.0 mm, outside diameter of 110.0 mm and width of 27.0 mm, weighing 1.25 kg. The bearing is fitted with shields on both sides (2Z) and a pressed steel sheet metal cage (JN). Limiting speed is 8000 1/min, reference speed 7700 1/min. Radial internal clearance is C3 (Group 3), wider than normal, which compensates for interference fits and thermal expansion during operation. The shielded design protects the raceway from coarse contaminants while retaining the internal grease fill, so the bearing is suited for applications where re-lubrication access is limited. The steel cage supports operation at the stated speed range and provides stable ball guidance under radial loading.
