This single row deep groove ball bearing carries balls between two grooved rings, with bore diameter 85.0 mm, outside diameter 150.0 mm and width 28.0 mm, giving a net mass of 1.798 kg. The cage is a steel sheet metal design (JN), and the radial internal clearance is increased per C4 (Group 4). Limiting speed is 6700.0 1/min, with a reference speed of 5300.0 1/min. The enlarged C4 clearance compensates for thermal expansion and interference fits under load, keeping the bearing free of excessive preload during operation at elevated temperatures or with tight fits. The steel sheet metal cage guides the balls at moderate speeds within the stated limiting and reference values, and the open bore type allows relubrication with grease or oil as required by the application.
