Deep groove ball bearing 6220-M-C3 carries radial and moderate axial loads through a single row of balls running in deep-groove raceways. Bore diameter is 100.0 mm, outside diameter 180.0 mm, width 34.0 mm, and net mass 3.84 kg. The cage is a solid brass type (M), permitting a limiting speed of 6500.0 1/min and a reference speed of 4800.0 1/min. The C3 radial internal clearance is wider than standard, compensating for temperature rise and interference fit during operation, which suits arrangements with tighter mounting fits or elevated running temperatures. The solid brass cage gives stable ball guidance and mechanical strength at the higher end of the speed range. As an open bearing without integrated seals or shields, it requires external sealing and a separate lubrication supply, either grease or oil, matched to the operating speed and temperature.
