Browning 767563 4-bolt Flange Bearing 1.25in Id Cast Iron

Product Description

The BROWNING 767563 is a 4-bolt flange bearing unit in the VF4S 100 Series, designed to support rotating shafts in medium-duty industrial and mechanical drive applications. The unit accepts a 1.25-inch inside diameter shaft and uses a 52100 steel ball bearing insert secured by a set screw lock. The cast iron housing measures 4.625 inches in overall length and 4.625 inches in overall height, with a static load capacity of 3,493 pounds and a dynamic load capacity of 5,782 pounds. Maximum operating speed is 2,500 RPM. Lubrication is required for proper operation. Weighing 3.52 pounds, this unit is built for applications where a rigid, bolted flange mount is needed.

This bearing unit is suited for conveyor systems, fan shafts, auger drives, and general industrial machinery where a 4-bolt flange mount provides secure, stable shaft support. The VF4S 100 Series configuration is commonly installed in agricultural equipment, material handling systems, and light manufacturing lines. Mounting hole centers are spaced 3.625 inches apart, accommodating standard 0.5-inch bolts. The unit fits horizontal, vertical, or angled mounting orientations typical of flange-mount installations.

Installation Notes

Installation is typically performed by a millwright or mechanical technician. De-energize and lock out all power to the drive system before removing or installing bearing units. Ensure the shaft and housing bore are clean and free of burrs before seating the insert. Apply appropriate grease through the lubrication fitting before placing the unit into service, and re-grease at intervals specified by the equipment manufacturer.
