Single row deep groove ball bearing with a steel sheet metal cage (JN design), bore 85.0 mm, outside diameter 130.0 mm, width 22.0 mm, net mass 0.917 kg. Limiting speed reaches 7100 1/min, reference speed 5800 1/min. Radial internal clearance is C3 (Group 3), wider than normal, and bore type Z is applied. Equivalent designs: SKF 6017/C3, NSK 6017C3, NTN 6017C3. The C3 clearance compensates for temperature-related fit tightening and shaft expansion under load, keeping the raceway geometry within design tolerance during operation. The steel sheet metal cage guides the balls with low friction and limited mass, matching the given speed ratings. As a single row deep groove ball bearing, it carries radial load together with moderate axial load in both directions, and its open design requires external sealing and separate lubrication with grease or oil suited to the reference speed.
