This deep groove ball bearing carries radial and moderate axial loads in a single row of balls, with contact sealing on both sides marked 2RSR that keeps grease inside and blocks contaminants from entering the raceway. Bore diameter is 40.0 mm, outside diameter 90.0 mm, and width 33.0 mm, giving a net mass of 0.882 kg. The cage is a steel sheet metal design (JN), and the limiting speed is rated at 4750.0 1/min. Radial internal clearance is C3 (Group 3), wider than normal, which compensates for thermal expansion during operation and shaft fit tightness. Because the seals are integrated, the bearing is factory-lubricated with grease and requires no external lubrication or maintenance during service. The C3 clearance combined with double-side sealing makes this bearing suitable for applications where operating temperature rises during use and where protection against dust or moisture ingress is required.
