This deep groove ball bearing carries radial and moderate axial loads on a single row of balls, with a bore of 55.0 mm, outside diameter of 120.0 mm and width of 29.0 mm. Mass is 1.348 kg. Both sides are covered with shields (Z), and the bearing uses a steel sheet metal cage of Generation C design (63..-C-2Z). Limiting speed is 7200 1/min, reference speed 7800 1/min. The internal clearance is increased, class C3, which compensates for tighter fits or thermal expansion during operation. Shields on both sides retain grease and keep out coarse contamination, so the bearing is supplied ready for grease lubrication without additional sealing. The C3 clearance combined with the steel cage makes this bearing suitable where shaft or housing tolerances push toward the tighter end of the fit range.
