This single row deep groove ball bearing carries a bore of 20.0 mm, outside diameter of 52.0 mm, and width of 15.0 mm, with a net mass of 0.14 kg. It runs with a C3 radial internal clearance (Group 3) and is fitted with a TVH cage made of plastic. The limiting speed reaches 19800 1/min, while the reference speed is 14400 1/min. The bore type is designated Z. The plastic TVH cage reduces friction and mass compared to metal cage designs, supporting stable operation at the stated speed values. The C3 internal clearance compensates for temperature-related expansion during operation, making the bearing suitable for applications where moderate thermal growth or shaft fit tightness must be accommodated. As an open bearing, relubrication access is direct, and mounting requires external sealing or shielding if contamination protection is needed. A dimensionally and constructionally equivalent bearing is SKF 6304-TN9/C3.
