This deep groove ball bearing carries radial and moderate axial loads on a single row of balls running in a raceway of 85.0 mm bore diameter, 180.0 mm outside diameter, and 41.0 mm width. It weighs 4.38 kg and is fitted with seals on both sides, a steel sheet metal cage (JN), and a C3 (Group 3) radial internal clearance. The limiting speed is 2350.0 1/min. The C3 clearance compensates for thermal expansion and interference fit tightening, keeping the bearing running smoothly under load without excessive play. The integrated seals retain grease inside the bearing and keep out contaminants, so no external sealing arrangement is required and relubrication intervals can be extended. Dimensionally and constructionally, it corresponds to SKF 6317-2RS1/C3, NSK 6317DDUC3, and NTN 6317LLUC3.
