This deep groove ball bearing carries radial loads in a single row of balls, with bore diameter 80.0 mm, outside diameter 140.0 mm and width 26.0 mm. The bearing has a solid brass cage (M) and a ceramic coating, at a net mass of 1.65 kg. Limiting speed is rated at 9500.0 1/min, with a reference speed of 5500.0 1/min. The ceramic coating provides electrical insulation, which keeps stray currents from passing through the rolling elements and prevents fluting damage on the raceways. The solid brass cage supports stable ball guidance at the stated speed values. Radial internal clearance is designated R$-$, and the bore type is Z. The construction suits applications requiring electrical insulation from the shaft or housing while running at the specified speed range.
