Browning 767584 Pillow Block Bearing 1.25 in Id Cast Iron

Product Description

The BROWNING 767584 is a two-bolt pillow block bearing in the VPS 100 Series, designed to support rotating shafts in standard industrial and mechanical drive applications. The bore measures 1-1/4 inches inside diameter with a straight bore profile and a set screw lock type for shaft retention. The housing is cast iron and the bearing insert is manufactured from 52100 bearing steel. Static load capacity is 2,567 pounds and dynamic load capacity is 4,381 pounds, making this unit well suited for moderate-to-heavy radial load service. Licensed HVAC, mechanical, and industrial maintenance technicians commonly specify this type of bearing for fan shaft and blower applications.

This pillow block is used in residential and commercial mechanical systems wherever a two-bolt, cast iron housing is required to mount a rotating shaft to a flat surface. The VPS 100 Series is a standard industrial pillow block line intended for general-purpose shaft support. Typical install scenarios include HVAC fan assemblies, conveyor drives, and pump shaft support where a 1-1/4 inch bore is required. The set screw lock allows secure shaft positioning without requiring a keyed bore.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician. De-energize and lock out the drive system before removing or installing any bearing assembly. Ensure the mounting surface is flat and the bolt holes align to the 4-23/32 inch center-to-center spacing before torquing fasteners. Set screws should be tightened against the shaft after proper shaft alignment is confirmed; do not over-tighten set screws, as this can damage the shaft or bearing insert.
