Browning 767506 4-bolt Flange Bearing 1-15/16 in Id

Product Description

The BROWNING 767506 is a VF4S-331 series 4-bolt flange bearing unit designed to support rotating shafts in industrial and commercial power transmission applications. It accepts a 1-15/16 inch bore shaft and houses a ball bearing insert made from 52100 steel, locked in place via set screw. The cast iron housing measures 6-3/8 inches in overall length and 6-3/8 inches in overall height, with a static load capacity of 5,216 pounds and a dynamic load capacity of 7,889 pounds. Rated to 2,500 RPM, this unit is well suited for conveyor drives, fan shafts, and general industrial equipment. Lubrication is required during installation and as part of routine maintenance.

This flange bearing is used in industrial and light commercial settings where a shaft must be mounted to a structural surface in a fixed-flange configuration. Typical applications include blower assemblies, material handling conveyors, agricultural equipment drives, and pump shaft supports. The 4-bolt mounting pattern and 5-1/8 inch bolt hole center-to-center spacing accommodate standard steel or structural iron mounting plates. The VF4S 300 series is a common fit for replacement and new-build installations handled by millwrights, maintenance technicians, and industrial mechanics.

Key Features

• 1-15/16 inch inside diameter accepts standard imperial shaft sizes
• 52100 steel ball bearing insert provides high load durability
• Cast iron housing resists deflection under heavy static and dynamic loads
• Set screw lock secures insert to shaft without additional hardware
• 5,216 pound static and 7,889 pound dynamic load ratings suit demanding applications
• Maximum 2,500 RPM rating covers most industrial fan and conveyor shaft speeds

Compatibility

Designed as an OEM-style replacement or direct-fit unit for applications requiring a 4-bolt flange bearing with a 1-15/16 inch bore in the VF4S 300 series configuration.

Installation Notes

Installation is typically performed by a millwright or qualified maintenance technician. Shut down and lock out the drive system before mounting or removing any bearing unit. Ensure the mounting surface is flat and the bolt pattern is aligned before torquing fasteners; use 5/8 inch mounting bolts per the housing specification. Apply grease through the lubrication fitting before placing the unit into service and follow the equipment manufacturer's relubrication interval.
