Browning 767596 4-bolt Flange Bearing 1-1/4 Inch Id Cast Iron

Product Description

The BROWNING 767596 is a 4-bolt flange bearing unit in the VF4S 100 series, designed for use in industrial rotating equipment and power transmission applications. It features a 1-1/4 inch bore with a ball bearing insert made from 52100 steel and a cast iron housing, delivering a static load capacity of 2,567 pounds and a dynamic load capacity of 4,381 pounds. The set screw lock secures the bearing insert to the shaft. Licensed HVAC technicians, millwrights, and industrial maintenance professionals install this unit in belt-driven systems, fans, conveyors, and other shaft-mounted assemblies requiring a bolted flange mount.

This bearing unit suits residential and commercial applications where a rigid, four-point mounted flange is required. Typical installations include fan shafts, blower assemblies, conveyor drives, and general industrial machinery. The VF4S 100 series is a standard product family for fixed-position shaft support where the shaft runs parallel to the mounting surface. Lubrication is required and must be serviced at regular intervals consistent with the operating load and speed.

Installation Notes

Installation is performed by qualified millwrights or industrial maintenance technicians. De-energize and lock out all power to the driven equipment before beginning work, following OSHA lockout/tagout procedures. Ensure the mounting surface is flat and clean before torquing the four mounting bolts, and verify shaft alignment before startup. Apply appropriate grease to the lubrication fitting before commissioning and at scheduled maintenance intervals.
