Carries radial loads and moderate axial loads in a single-row deep groove ball bearing design with a bore diameter of 50.0 mm, outside diameter of 80.0 mm, and width of 16.0 mm. The bearing weighs 0.262 kg and is rated for a limiting speed of 4450.0 1/min. It is fitted with seals on both sides (2RSR) and a steel sheet metal cage (JN), with a bore type Z. Radial internal clearance is C3 (Group 3), wider than standard. The sealed design keeps grease inside and prevents contaminants from entering, so the bearing is factory lubricated and does not require external relubrication under normal conditions. The C3 clearance compensates for thermal expansion and interference fits, making the bearing suitable where operating temperatures raise the shaft or housing fit beyond standard clearance limits. Dimensionally and functionally equivalent to SKF 6010-2RS1/C3, NSK 6010DDUC3, and NTN 6010LLUC3.
