This deep groove ball bearing carries radial loads on 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. It features a solid brass cage (M) with a ceramic coating, weighs 4.319 kg, and is rated for a limiting speed of 7000.0 1/min and a reference speed of 5500.0 1/min. The radial internal clearance corresponds to C4 (Group 4), providing greater internal play than standard clearance, which accommodates thermal expansion and shaft fit conditions where a tighter fit would otherwise reduce running clearance excessively. The ceramic coating on the cage supports electrical insulation properties, reducing the risk of current passage through the bearing. The solid brass cage design offers stability at the stated speed ratings, while the bore type Z designation reflects the specific bore configuration of this variant.
