Browning 767604 4-bolt Flange Bearing 3/4 Inch Id

Product Description

The BROWNING 767604 is a 4-bolt flange bearing unit designed for shaft support applications in industrial and mechanical drive systems. The unit houses a ball bearing insert with a 3/4 inch bore, secured by a set screw lock, inside a cast iron flange housing measuring 3-3/8 inches overall length by 3-3/8 inches overall height. It carries a static load capacity of 1,444 pounds and a dynamic load capacity of 2,611 pounds, making it well suited for moderate-to-heavy radial load applications. The bearing insert is manufactured from 52100 steel and requires periodic lubrication. This unit is typically installed by millwrights, maintenance technicians, or mechanical contractors working on conveyor systems, fan assemblies, or rotating shaft arrangements.

This flange bearing is appropriate for use in both light industrial and commercial mechanical systems where a 4-bolt mounting pattern is required. The 2-1/2 inch center-to-center mounting hole spacing and 3/8 inch bolt size allow for straightforward alignment and fastening to steel or fabricated frames. With a maximum rated speed of 4,000 RPM, it covers a broad range of fan, blower, and conveyor drive applications. The VF4S 100 series designation identifies the housing and insert configuration within the BROWNING flange unit product line.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. Disconnect and lock out all power to the drive system before mounting or servicing this bearing unit. Align the shaft carefully before tightening set screws to avoid premature bearing wear, and ensure the mounting surface is flat and rigid. Apply the appropriate grease at installation per the lubricant manufacturer and bearing service interval recommendations.
