Rexnord Link-Belt PKB22464H Pillow Block Bearing

Rexnord Link-Belt PKB22464H Pillow Block Bearing is a solid-housed, two-bolt mounting unit that houses a 4-inch-bore spherical roller bearing on a flat base. The cast-iron housing is powder-coated black and designed for fixed mounting with a 4-inch bore, base length 15.25 inches, and a bolt-center-to-center spacing of 11.75 inches for 1-inch bolts. The base-to-centerline height is 4.25 inches and overall height is 15.75 inches, with an end cap identified as B464DTC. The unit is relubricatable through a 1/8 NPT grease fitting and uses a steel cage inside the housing for durability. Seals options include a clearance seal by default, with optional E Lip, H Labyrinth, or E7 Triple Lip seals to tailor contamination protection and lubrication retention. This PKB22464H variant is part of Rexnord’s Link-Belt line of pillow block spherical roller bearing housings, configured as a 2-bolt pillow block, suitable for mounting a 4-inch shaft in a wide range of industrial machinery where robust support and straightforward lubrication are priorities. With its 4-inch bore and rugged cast-iron construction, the PKB22464H provides a reliable foundation for shaft-mounted assemblies requiring precise alignment and long service life.
