This deep groove ball bearing carries radial and moderate axial loads in a single row of balls, with a bore of 120.0 mm, outside diameter of 215.0 mm, and width of 40.0 mm. Net mass is 6.4 kg. The cage is a solid brass design (M), allowing a limiting speed of 5500.0 1/min and a reference speed of 4250.0 1/min. Radial internal clearance is C3 (Group 3), which is wider than normal. The C3 clearance compensates for tighter fits and thermal expansion during operation, keeping the bearing free of excessive preload at working temperature. The solid brass cage gives stable ball guidance at the higher end of the speed range and adds resistance to cage wear under continuous rotation. No seals or shields are fitted, so lubrication and contamination protection must be provided externally by the housing design.
