Browning 767594 4-bolt Flange Bearing 1 Inch Id

Product Description

The BROWNING 767594 is a 4-bolt flange bearing unit in the VF4S 100 Series, designed to support rotating shafts in stationary equipment across industrial and mechanical drive applications. The housing is cast iron with a 52100 steel ball bearing insert, giving it durability in demanding environments. The bore accepts a 1-inch shaft secured by a set screw lock. Static load capacity is 1,651 pounds and dynamic load capacity is 2,801 pounds, making it well suited for moderate to heavy radial loads. Licensed millwrights, maintenance mechanics, and HVAC equipment installers typically handle this type of bearing replacement.

This bearing unit is used in belt-driven systems such as blowers, fans, conveyors, and pump assemblies where a 4-bolt flange mount is required. It fits applications calling for a 1-inch bore with set screw locking in a compact square-flange footprint. The VF4S 100 Series is a standard industrial configuration commonly found in commercial HVAC air handling equipment, light industrial machinery, and general power transmission assemblies. Lubrication is required for proper service life, and the unit is rated to a maximum of 3,500 RPM.

Installation Notes

Installation is typically performed by a licensed millwright or qualified maintenance mechanic. De-energize all equipment and lock out or tag out power sources before removing or installing bearing units. Ensure the mounting surface is flat and clean, and torque all four flange bolts evenly to avoid misalignment. Apply appropriate grease to the lubrication fitting before placing the unit into service, as this bearing requires lubrication.
