This deep groove ball bearing carries radial and moderate axial loads through a single row of balls guided by a solid brass cage. Bore diameter is 120.0 mm, outside diameter 180.0 mm, width 28.0 mm, and net mass 2.64 kg. Limiting speed reaches 6500.0 1/min, with a reference speed of 4450.0 1/min, allowing sustained operation at higher rotational speeds than a standard pressed cage design would permit. The C3 radial internal clearance (Group 3) is wider than standard, compensating for thermal expansion during operation and allowing use where shaft and housing fits or temperature rise would otherwise tighten the running clearance. The solid brass cage, marked M, provides strength and dimensional stability at elevated speeds and temperatures. No seals or shields are fitted, so external lubrication and protection must be provided separately, and grease or oil lubrication can be selected according to the application's speed and temperature requirements.
