Carries radial loads and moderate axial loads in a single-row ball bearing arrangement with a 55.0 mm bore, 100.0 mm outside diameter, and 21.0 mm width. This deep groove ball bearing, generation C design, is fitted with shields on both sides and a steel sheet metal cage (JN). Net mass is 0.588 kg, limiting speed reaches 8800 1/min, and reference speed is 8300 1/min. Radial internal clearance falls in the CN (normal) group, suitable for standard fit conditions without additional preload requirements. The shields protect the raceway and balls from dust ingress while retaining factory-applied grease, reducing maintenance needs in continuous operation. The steel sheet metal cage supports stable ball guidance at the stated speed range, making the bearing suitable for shaft mounting where moderate combined loads and standard running clearance are required.
