Carries radial loads and moderate axial loads in a single-row deep groove ball bearing design with a steel sheet metal cage (JN). Bore diameter is 17.0 mm, outside diameter 62.0 mm, width 17.0 mm, and net mass 256.0 g. Limiting speed reaches 16200 1/min, with a reference speed of 11600 1/min. Radial internal clearance corresponds to C3 (Group 3), giving a looser fit than standard clearance to compensate for thermal expansion during operation. The C3 clearance class makes this bearing suitable where operating temperatures raise the effective preload of a standard-clearance bearing, helping maintain smooth rotation without excessive internal stress. The steel sheet metal cage keeps the assembly light while guiding the balls reliably at the stated speed range. Equivalent references from other manufacturers include SKF 6403/C3, NSK 6403C3, and NTN 6403C3.
