This deep groove ball bearing carries radial and moderate axial loads in a single row configuration with a bore diameter of 8.0 mm, outside diameter of 22.0 mm, and width of 7.0 mm, giving a net mass of 0.012 kg. The steel sheet metal cage (JN) guides the balls, and the limiting speed is rated at 21700.0 1/min under the stated conditions. Seals on both sides (2RSR) protect the raceway from contamination and retain grease inside the bearing, so no external relubrication path is required during operation. Radial internal clearance is CN (Group N), the standard clearance class suitable for typical operating conditions without special shaft or housing fits. The design is intended for applications where sealed protection and a compact size are required within the stated speed and dimensional limits.
