Deep groove ball bearing 6013-2RSR-C3 carries radial and moderate axial loads on a bore of 65.0 mm, outside diameter 100.0 mm and width 18.0 mm, at a net mass of 0.437 kg. It is a single row design with a steel sheet metal cage (JN) and seals on both sides, giving a limiting speed of 3500 1/min. Internal clearance is C3 (Group 3), wider than standard, which compensates for temperature rise during operation and shaft fit tolerances. The double-side seals keep the grease fill enclosed and block dust and moisture ingress, so this bearing suits applications where relubrication access is limited. The C3 clearance makes it a suitable choice where operating temperature increases the effective internal clearance or where interference fits on shaft and housing would otherwise remove all working clearance. Dimensionally and constructionally it corresponds to SKF 6013-2RS1/C3, NSK 6013DDUC3, and NTN 6013LLUC3.
