This deep groove ball bearing carries radial and moderate axial loads on a shaft of 45.0 mm bore diameter, matched with an 85.0 mm outside diameter and 19.0 mm width. It is a single row, Generation C design with shields on both sides, fitted with a steel sheet metal cage (JN), giving a net mass of 0.405 kg. The limiting speed is 10800 1/min, with a reference speed of 9900 1/min. The radial internal clearance is C3, larger than standard, which compensates for tighter fits or thermal expansion during operation. The shields on both sides retain lubricant and keep out coarse contamination, so the bearing suits applications where relubrication access is limited. The steel cage design supports stable ball guidance across the stated speed range, and the C3 clearance combined with the compact width makes this bearing suitable for shaft mountings where a slight interference fit is expected.
