This deep groove ball bearing carries radial and moderate axial loads in a single row of balls running between solid rings. Bore diameter is 85.0 mm, outside diameter 180.0 mm, width 41.0 mm, and net mass is 4.972 kg. The cage is a solid brass type (M), and the bearing features a ceramic-coated bore and outside diameter (J20AA). Limiting speed is 6600 1/min, reference speed 5300 1/min. Radial internal clearance is C3, providing extra clearance to compensate for tighter fits or thermal expansion during operation. The solid brass cage adds strength and stability at higher speeds and temperatures, while the ceramic coating on the mating surfaces provides electrical insulation, reducing the risk of current passage through the bearing. No sealing is fitted, so relubrication and external protection must be provided by the housing design.
