Browning 767965 4-bolt Flange Bearing 1-15/16 in Bore

Product Description

The BROWNING 767965 is a VF4S-231 series 4-bolt flange bearing unit designed for industrial shaft support applications. It accepts a 1-15/16 inch bore and uses a ball bearing insert made from 52100 steel, locked to the shaft via set screw. The cast iron housing measures 5-5/8 inches in overall length and 5-5/8 inches in overall height, with a bolt hole center-to-center spacing of 4-3/8 inches. Static load capacity is 5,216 pounds and dynamic load capacity is 7,889 pounds, making this unit suitable for moderate-to-heavy radial load applications. Maximum operating speed is 3,000 RPM. The unit requires periodic lubrication to maintain bearing performance.

The BROWNING 767965 is used in industrial and commercial equipment installations where a shaft must be supported at a fixed mounting point. Typical applications include conveyor drives, fan assemblies, pump mounts, and general power transmission equipment. The 4-bolt flange configuration provides a stable, rigid mount to flat surfaces such as equipment frames or baseplate assemblies. Installation is performed by millwrights, industrial maintenance technicians, and mechanical contractors working on rotating equipment.

Installation Notes

Installation should be performed by a qualified millwright or maintenance technician familiar with rotating equipment and shaft alignment procedures. De-energize and lock out all power to the drive system before removing the existing bearing unit or mounting the replacement. Ensure the mounting surface is flat and clean before torquing the four flange bolts. Apply appropriate grease to the bearing insert through the lubrication fitting before placing the unit into service, and follow the equipment manufacturer's recommended re-lubrication intervals.
