Browning 767501 4-bolt Flange Bearing 1-11/16 in Bore

Product Description

The BROWNING 767501 is a 4-bolt flange bearing unit from the VF4S 300 Series, designed for industrial power transmission and mechanical drive applications. The unit features a 1-11/16 inch bore with a set screw lock and is housed in a cast iron flange body measuring 5-5/8 inches in both overall length and overall height. The bearing insert is manufactured from 52100 steel and requires lubrication. With a static load capacity of 5,216 pounds and a dynamic load capacity of 7,889 pounds, this unit is suited for demanding rotary shaft applications where rigid, four-point mounting is required. Licensed HVAC and industrial technicians, millwrights, and mechanical contractors install this type of unit in fan assemblies, conveyor drives, and similar rotating equipment.

The BROWNING 767501 is intended for use in applications requiring a four-bolt flange mount with a medium-bore shaft interface. The VF4S 300 Series is commonly installed in commercial and industrial settings involving belt-driven fan systems, blower shafts, pump drive assemblies, and conveyor equipment. The 4-bolt pattern provides stable, rigid mounting on flat surfaces. The unit is rated to a maximum of 3,000 RPM, making it appropriate for moderate-speed continuous-duty applications. No specific OEM model compatibility was provided in the product data.

Installation Notes

Installation is typically performed by millwrights, industrial mechanics, or mechanical contractors. De-energize and lock out all equipment before removing or installing bearing units. Ensure the mounting surface is flat, clean, and free of debris before torquing flange bolts. After installation, verify shaft alignment and apply grease through the lubrication fitting before returning the assembly to service, following the equipment manufacturer's maintenance schedule.
