This deep groove ball bearing carries radial and moderate axial loads in a single row of balls running in a solid brass cage (M). Bore diameter is 80.0 mm, outside diameter 170.0 mm, width 39.0 mm, and net mass 4.31 kg. The limiting speed reaches 7000 1/min, with a reference speed of 5500 1/min, giving an indication of the thermal speed capability under normal operating conditions. The radial internal clearance is C3 (Group 3), wider than standard, which compensates for tighter fits or thermal expansion during operation. The solid brass cage adds strength and dimensional stability at higher speeds and temperatures compared to pressed steel cages. This bearing is supplied without an integral seal or shield, so external sealing and lubrication provisions must be arranged separately in the housing design.
