This deep groove ball bearing carries radial and moderate axial loads in a compact single-row design, with a bore diameter of 7.0 mm, outside diameter of 19.0 mm, and width of 6.0 mm. The mass is 8.0 g, and the limiting speed reaches 26500 1/min. Sealing is provided on both sides (2RSR), and the cage is made of steel sheet metal, type JN. The radial internal clearance is C3, wider than standard, which compensates for tighter fits and thermal expansion during operation. The seals on both sides retain grease and keep out contamination, making the bearing suitable for maintenance-free operation once lubricated. Given its small dimensions and steel cage construction, this bearing fits applications requiring compact, sealed, low-mass rotational support at moderate to high speeds.
