This deep groove ball bearing carries radial and moderate axial loads in a single row of balls, with a bore diameter of 40.0 mm, outside diameter of 68.0 mm, and width of 15.0 mm. The unit has a net mass of 0.19 kg and features a solid laminated fabric cage (TB). Limiting speed is rated at 14600 1/min, with a reference speed of 10600 1/min, giving the design margin for sustained operation under normal thermal conditions. The C3 radial internal clearance (Group 3) provides a larger-than-standard clearance, compensating for thermal expansion during operation and shaft fit interference. The P6 accuracy class ensures tighter dimensional and running tolerances than standard P0, suitable for applications requiring improved rotational precision. As an open bearing without integrated seals, it requires external lubrication and sealing arrangements appropriate to the operating environment.
