Browning 767888 Pillow Block Bearing 1 in Id Cast Iron

Product Description

The BROWNING 767888 is a two-bolt pillow block bearing unit in the VPS 300 series, designed to support rotating shafts in light-to-medium industrial and mechanical drive applications. The unit features a 1-inch straight bore with a set screw locking arrangement and a cast iron housing that encases a 52100 bearing steel ball insert. Static load capacity is 2,567 pounds and dynamic load capacity is 4,381 pounds, making this unit appropriate for moderate radial loads in conveyor, fan, pump, and general power transmission installations. Licensed millwrights, maintenance technicians, and mechanical contractors are the typical installers.

This pillow block is suited for industrial machinery, agricultural equipment, material handling systems, and light manufacturing lines where a standard two-bolt foot-mount bearing is required. The VPS 300 series is a common configuration used in shaft support applications across both fixed and portable equipment. The straight bore and set screw lock are compatible with standard keyed shafting. Overall length is 6-3/16 inches, overall height is 3-11/32 inches, and the base-to-center height is 1-3/4 inches, which suits standard mounting plate layouts.

Installation Notes

Installation is performed by licensed millwrights or qualified maintenance technicians. Shut down and lock out all power to the drive system before removing or installing any bearing unit. Ensure the mounting surface is flat and clean before torquing the mounting bolts to prevent housing distortion. Verify shaft diameter and keyway dimensions match the bore and lock type before final assembly.
