This deep groove ball bearing carries radial and moderate axial loads through a single row of balls running in a steel sheet metal cage (JN). Bore diameter is 170.0 mm, outside diameter 260.0 mm, width 42.0 mm, and net mass 7.1 kg. The limiting speed is rated at 3400 1/min, with a reference speed of 3550 1/min, giving a defined thermal and mechanical speed reference for the design. The C3 internal clearance (Group 3) provides increased internal play, compensating for thermal expansion during operation and shaft fit tolerances. This design suits applications where moderate speed operation and stable radial guidance are required, without built-in seals or shields, so external sealing and lubrication must be provided separately. Dimensionally and constructionally equivalent to SKF 6034/C3, NSK 6034C3, and NTN 6034C3.
