SKF 7311-BEAGY Angular Contact Ball Bearing

SKF 7311-BEAGY angular contact ball bearing is a single-row unit engineered to carry combined radial and axial loads in one direction, thanks to its 40-degree contact angle. It features a 55 mm bore, 120 mm outer diameter, and 29 mm width, and is supplied in an open configuration with a brass cage. The balls are chrome steel (100Cr6), delivering durability and smooth rotation, while the absence of seals or shields supports flexible lubrication approaches. This bearing is part of SKF's 7300 series of single-row angular contact bearings, designed for high-speed operation and precise load distribution in equipment where axial and radial forces occur together. The 7311-BEAGY designation identifies this exact bore-width-cage configuration within SKF's catalog, ensuring proper interchangeability with mating components in assemblies that require duplex or tandem arrangements for greater stiffness when needed.
