Carries radial and moderate axial loads on a shaft of 50.0 mm bore, running against a 90.0 mm outside diameter and 20.0 mm width. The bearing weighs 470.0 g and is a single row deep groove ball bearing with seals on both sides (RSR), fitted with a steel sheet metal cage (JN). Internal clearance is C3 (Group 3), wider than normal, and the limiting speed is rated at 4300.0 1/min. The C3 clearance compensates for temperature rise and interference fits, making this bearing suitable where shaft and housing tolerances or thermal expansion would otherwise tighten the running clearance. The integrated seals on both sides retain the internal grease fill and keep out contamination, so no external sealing arrangement is required and relubrication intervals can be extended. Equivalent designations for this size and configuration are SKF 6210-RS1/C3, NSK 6210DUC3, and NTN 6210LUC3.
