This deep groove ball bearing carries radial and moderate axial loads on a single row of balls, with a bore of 35.0 mm, outside diameter of 80.0 mm, and width of 21.0 mm. Net mass is 0.464 kg, the limiting speed is 5400.0 1/min, and the cage is made of steel sheet metal (JN type). Seals are fitted on both sides, and the radial internal clearance is C3 (Group 3), which is wider than normal clearance. The C3 clearance compensates for thermal expansion during operation and shaft fit tolerances, making this bearing suitable where temperature rise under load is expected. The seals on both sides retain grease inside the bearing and block dirt and moisture ingress, so no external sealing arrangement is required. Dimensional and constructional equivalents include SKF 6307-2RS1/C3, NSK 6307DDUC3, and NTN 6307LLUC3.
