This deep groove ball bearing carries radial and moderate axial loads in a single row configuration, running on a solid brass cage (designation M) that keeps the balls evenly spaced at higher speeds. Bore diameter is 150.0 mm, outside diameter 320.0 mm, and width 65.0 mm, with a net mass of 26.5 kg. Limiting speed is 3600.0 1/min and reference speed 3000.0 1/min. The C3 radial internal clearance provides extra play to compensate for thermal expansion under load, which suits applications with elevated operating temperatures. The solid brass cage adds strength and stability at the upper speed range compared to lighter cage materials, and the bearing is supplied without any additional sealing, so lubrication and contamination protection must be provided externally through the housing design.
