This deep groove ball bearing supports radial loads and moderate axial loads in a single row of balls, with a bore diameter of 80.0 mm, outside diameter of 170.0 mm, and width of 39.0 mm. The bearing weighs 4.37 kg and features a solid brass cage (M) with a ceramic coating, allowing a limiting speed of 7000.0 1/min and a reference speed of 5500.0 1/min. The radial internal clearance is C3 (Group 3), providing additional clearance to compensate for thermal expansion during operation at elevated speeds or temperatures. The solid brass cage offers strength and stability under higher rotational speeds, while the ceramic coating supports electrical insulation properties, reducing the risk of current-related damage to the rolling elements and raceways.
