This deep groove ball bearing carries radial loads and moderate axial loads through a single row of balls guided by a steel sheet metal cage. Bore diameter is 15.0 mm, outside diameter 42.0 mm, width 13.0 mm, and net mass 0.088 kg. Limiting speed is rated at 24400 1/min, with a reference speed of 16500 1/min. Radial internal clearance is set to C3 (Group 3), wider than the standard range, and the cage is of JN design, with bore type Z. The C3 clearance allows the bearing to absorb thermal expansion of the shaft and compensate for interference fits without excessive preload, keeping the rotating elements free-running under such conditions. The JN cage supports stable ball guidance across the rated speed range while keeping added mass low, matching the 0.088 kg net weight. No sealing or shielding is specified, so protection from contamination and lubricant retention depend entirely on the surrounding housing arrangement and the lubricant chosen for the application.
