This deep groove ball bearing carries seals on both sides and runs on a steel sheet metal cage, sealing the raceway against contamination while retaining lubricant inside the housing. Bore diameter is 17.0 mm, outside diameter 35.0 mm, width 10.0 mm, and net mass is 39.5 g. Radial internal clearance is C3 (Group 3), giving a larger operating clearance than standard, and the limiting speed is rated at 11800.0 1/min. The C3 clearance compensates for thermal expansion and interference fit tightening, making this bearing suitable for applications with elevated operating temperatures or press-fit mounting on the shaft or in the housing. Sealing on both sides removes the need for external protection and allows operation without relubrication over the service life. Dimensionally and constructionally equivalent designations include SKF 6003-2RS1/C3, NSK 6003DDUC3, and NTN 6003LLUC3.
