Browning 767345 Pillow Block Bearing 1.5 in Id Cast Iron

Product Description

The BROWNING 767345 is a cast iron pillow block bearing in the VPS 100 Series, designed to support rotating shafts in industrial and mechanical drive applications. It accepts a 1.5-inch straight bore shaft and uses a ball bearing insert made from 52100 bearing steel, secured with a set screw lock. The housing spans 7.125 inches overall length and stands 4 inches overall height, with a base-to-center height of 2 inches. Static load capacity is 4,467 pounds and dynamic load capacity is 7,340 pounds. Licensed HVAC, mechanical, and general industrial technicians install this bearing in fan, blower, conveyor, and pump shaft assemblies where reliable radial load support is required.

The 767345 pillow block is suited for light-to-medium duty rotating equipment in commercial HVAC systems, industrial fans, blowers, and conveyor drives. The two-bolt mounting pattern with 5.375-inch center-to-center spacing allows straightforward mounting to steel or structural frames. The VPS 100 Series is a standard catalog line intended for applications with shaft speeds up to 2,500 RPM. The cast iron housing provides structural rigidity and corrosion resistance adequate for indoor mechanical room and equipment platform environments.

Installation Notes

Installation is performed by licensed millwrights, HVAC mechanics, or industrial maintenance technicians. Shut down and lock out the drive system before removing or installing any bearing assembly. Align the pillow block housing to the shaft centerline before tightening mounting bolts to ensure even load distribution across both mounting points. Set screws should be tightened to the shaft flat or shaft keyway after final alignment is confirmed; do not overtighten set screws against a plain shaft without a flat, as this can cause shaft damage and premature bearing failure.
