Rexnord C251-316 Two-Bolt Pillow Block Bearing

Rexnord C251-316 Two-Bolt Pillow Block Bearing is a rugged, fixed-housing solution designed to support a rotating shaft in industrial equipment. It accommodates a 1-3/16 in bore shaft, with a two-bolt mounting pattern that provides a compact, stable base when attached to a machine frame. As part of Rexnord's pillow block family, the C251-316 is intended to accept compatible Rexnord insert bearings sized for a 1-3/16 in bore, enabling straightforward replacement and consistent mounting footprints across Rexnord's light- to medium-duty line. This bearing block is well-suited for conveyors, fans, pumps, and other general machinery where reliable shaft support and easy maintenance are valued. The two-bolt configuration helps achieve even clamping on the base, promoting proper alignment and extending service life when the housing is properly torqued and lubricated per manufacturer guidelines. With the C251-316 designation, technicians can reliably identify the correct bore size for bearing inserts and compatible shaft assemblies within Rexnord's standardized pillow block interfaces.
