Browning 767753 4-bolt Flange Bearing 1-7/16 in Bore

Product Description

The BROWNING 767753 is a 4-bolt flange bearing unit in the VF4S 100 series, designed to support rotating shafts in industrial and commercial mechanical drive applications. It combines a ball bearing insert made from 52100 steel with a cast iron housing, offering a static load capacity of 3,493 pounds and a dynamic load capacity of 5,782 pounds. The 1-7/16 inch bore accepts a standard shaft and is secured via a set screw lock. Maximum rated speed is 2,500 RPM. This unit is installed by millwrights, maintenance mechanics, and industrial technicians working on conveyor systems, fans, pumps, and similar rotating equipment.

The VF4S-123 flange unit is suited for light-to-medium industrial applications where a rigid, bolted mounting point is required. The 4-bolt mounting pattern with bolt hole centers spaced 3-5/8 inches apart provides a stable, square footprint on equipment frames and mounting plates. The overall length and height are each 4-5/8 inches, making it a compact unit for its load rating. Lubrication is required during installation and at regular service intervals per the equipment manufacturer's maintenance schedule.

Installation Notes

Installation should be performed by a qualified millwright or maintenance mechanic. De-energize and lock out all power to the drive system before removing or installing bearing units, following applicable OSHA lockout/tagout procedures. Ensure the mounting surface is flat and clean before torquing bolts, and align the shaft carefully to avoid side-loading the bearing. Apply the specified grease before initial startup and establish a relubrication interval based on operating speed, load, and environment.
