This deep groove ball bearing carries radial loads in a single row of balls, with a bore of 90.0 mm, outside diameter of 190.0 mm, and width of 43.0 mm. It is fitted with a solid brass cage (M) and ceramic-coated construction, weighing 6.0 kg. The limiting speed is 6300.0 1/min, with a reference speed of 5100.0 1/min. Radial internal clearance is C3 (Group 3), giving a looser fit that accommodates thermal expansion under higher operating temperatures or interference fits. The ceramic coating provides electrical insulation of the bearing seats, making it suitable for applications where shaft currents need to be interrupted. As an open bearing, relubrication access is unobstructed, and the solid brass cage supports stable ball guidance at the stated speed range.
