This deep groove ball bearing carries radial and limited axial loads in a single row of balls, with shields on both sides to keep the raceway protected. Bore diameter is 30.0 mm, outside diameter 62.0 mm, and width 16.0 mm, giving the basic mounting envelope. Net mass is 0.192 kg. The cage is a steel sheet metal design, designation JN. Limiting speed is rated at 15100 1/min, reference speed at 13400 1/min. Radial internal clearance is C3 (Group 3), wider than normal, which allows for thermal expansion during operation and helps prevent excessive preload once the bearing reaches working temperature. The shielded (2Z) construction retains lubricant and blocks coarse contaminants from entering the raceway, suiting applications where relubrication access is limited. Bore type Z should be checked against the shaft fit drawing on the product card before mounting.
