MRC 311RDU Single Row Angular Contact Ball Bearing

The MRC 311RDU is a single-row angular contact ball bearing with a cylindrical bore, manufactured by MRC to serve as a compact, high-precision support element in rotating machinery. The 311RDU designation identifies this exact geometry and bore style within MRC's line of angular contact bearings, signaling a design optimized for inline assemblies where a cylindrical bore is required. In an angular contact configuration, the raceways are angled relative to the bearing axis, allowing the bearing to accommodate axial loads in combination with radial loads along a single contact line in a compact, single-row form. The cylindrical bore supports straightforward mounting in shafts or housings designed for that bore style, which helps maintain accurate alignment and reduces the complexity of integrating the bearing into tight spaces. This MRC bearing is suited for precision-driven equipment and drive systems where reliable support in a small-footprint package is essential, with the familiar performance characteristics associated with MRC angular contact bearings.
