This deep groove ball bearing carries radial and moderate axial loads on a single row of balls, with a bore of 80.0 mm, outside diameter of 170.0 mm, and width of 39.0 mm. The net mass is 4.319 kg. The bearing uses a solid brass cage (M) and features a ceramic coating on the bore, designated J20AA, which provides electrical insulation. Limiting speed is rated at 7000.0 1/min, with a reference speed of 5500.0 1/min. Radial internal clearance is C3 (Group 3), giving greater internal play than standard clearance, which helps accommodate thermal expansion and shaft deflection during operation. The ceramic-coated bore (J20AA) provides insulation against passage of electrical current through the bearing, protecting the rolling elements and raceways from electrical damage. The solid brass cage offers stable ball guidance and strength at the rated speeds. As an open bearing without integrated sealing, it requires external protection and a separate lubrication supply appropriate to the operating conditions.
