This single row deep groove ball bearing carries the designation 6210-C-2Z-L506-C3>V, with a bore of 50.0 mm, outside diameter of 90.0 mm, and width of 20.0 mm. The bearing has a net mass of 0.45 kg and is fitted with shields on both sides (2Z) and a steel sheet metal cage of design JN. Radial internal clearance is C3 (Group 3), providing more internal play than the standard clearance range. Limiting speed is rated at 9900 1/min, with a reference speed of 9200 1/min. The shields on both sides restrict the ingress of solid contaminants while retaining the internal lubricant fill designated L506. The C3 clearance compensates for temperature rise and interference fit effects during operation, keeping the bearing free of excessive preload once mounted. The steel sheet metal cage suits moderate to higher rotational speeds within the stated limiting and reference values, and the Generation C design (bore type Z) reflects the current optimized internal geometry for this bearing series.
