Carries radial and moderate axial loads on a shaft of 50.0 mm bore, with a 90.0 mm outside diameter and 20.0 mm width. This deep groove ball bearing is a single row design with seals on both sides and a pressed steel sheet metal cage (JN). Net mass is 458.0 g, radial internal clearance is CN (Group N), and the limiting speed is 4300.0 1/min. The integrated seals keep grease in and contaminants out, so relubrication is not required in service, which suits applications where the bearing position is difficult to access. Standard CN clearance combined with the JN cage arrangement allows normal running conditions without special mounting adjustments. Equivalent designations for this design are SKF 6210-2RS1, NSK 6210DDU, and NTN 6210LLU.
