Rexnord 22309LBC3 Bearing

The Rexnord Link-Belt 22309LBC3 is a spherical roller bearing insert (unmounted replacement) in the Link-Belt family, designed to accommodate heavy radial loads and the misalignment that spherical rollers are built to tolerate. It features a two-piece outer ring construction, a hallmark of Link-Belt spherical roller bearings, which helps improve mounting alignment and installation in compatible housings. The 22309LBC3 has a bore diameter of 45 mm (1.77 in), an outside diameter of 100 mm (3.937 in), and a width of 36 mm (1.417 in), yielding a 45x100x36 mm footprint. This size is cataloged alongside the related 22309LBKC3 variant, providing an explicit cross-reference within Rexnord’s unmounted replacement lineup. As an inserts-type bearing, it is intended to be paired with a corresponding Rexnord Link-Belt bearing housing rather than sold as a stand-alone full assembly. The LBC3 suffix designates the bearing’s internal clearance category within Rexnord’s size-class family, and the part is positioned among other 2230xLBC3-series inserts in the manufacturer’s catalog. In practical terms, this component serves as a drop-in replacement element for existing Link-Belt spherical roller bearing assemblies where a 45 mm bore and 100 mm outer diameter are required.
