This deep groove ball bearing carries radial and moderate axial loads while running at a bore diameter of 55.0 mm, outside diameter of 90.0 mm and width of 11.0 mm. The single-row design uses a steel sheet metal cage (JN), keeping net mass at 0.259 kg. Radial internal clearance is set to CN (Group N), and the limiting speed reaches 10900.0 1/min, with a reference speed of 6000.0 1/min. The narrow cross-section suits applications with restricted axial space where standard radial clearance is sufficient. The steel sheet metal cage supports operation at the stated speed range without added mass, and the CN clearance class allows normal fit conditions without preload. As a single-row deep groove ball bearing, it accommodates a combination of radial load with limited axial load in both directions, provided mounting and lubrication are matched to the reference speed given.
