Supports radial loads and moderate axial loads through a single row of balls running in deep grooves, with a steel sheet metal cage (JN) guiding the ball set. Bore diameter is 17.0 mm, outside diameter 35.0 mm, width 10.0 mm, and net mass is 37.0 g. Limiting speed reaches 31000 1/min, with a reference speed of 20300 1/min. Radial internal clearance is C3 (Group 3), which is wider than standard clearance. The C3 clearance compensates for temperature rise and interference fits during operation, keeping the bearing free of excess preload at higher speeds. This deep groove ball bearing is equivalent to SKF 6003/C3, NSK 6003C3, and NTN 6003C3, allowing direct substitution where the same bore, outside diameter, and clearance class are required.
