Browning 767895 4-bolt Flange Bearing 1.5 in Id Cast Iron

Product Description

The BROWNING 767895 is a 4-bolt flange bearing unit in the VF4S 200 Series, designed for industrial shaft support applications where a rigid, cast iron housing is required. Built around a 1.5-inch bore, this unit accepts a ball bearing insert made from 52100 steel and uses a set screw lock to secure the shaft. It carries a static load capacity of 4,467 pounds and a dynamic load capacity of 7,340 pounds, making it suitable for moderate-to-heavy duty rotating equipment. The housing measures 5.125 inches in overall length and 5.125 inches in overall height. Installation is handled by maintenance technicians and millwrights working on conveyor systems, fans, pumps, and similar power transmission equipment.

The VF4S-224 flange unit is applied in industrial and commercial settings where a 4-bolt mounting pattern provides stable, secure housing on a machine frame or base plate. With a 4-inch center-to-center bolt hole spacing and 0.5-inch bolt size, it mounts to standard machine frames without modification. It is rated to 3,500 RPM maximum and requires periodic lubrication through the standard grease fitting. Typical applications include conveyor drives, blower shafts, agricultural equipment, and light manufacturing machinery where a reliable fixed-mount bearing housing is needed.

Installation Notes

Installation is typically performed by a qualified millwright or maintenance mechanic. Shut down and lock out all power to the driven equipment before removing or installing the bearing unit. Ensure the mounting surface is flat and clean to prevent housing distortion that could affect bearing alignment. Tighten set screws to shaft per the equipment manufacturer's specification and apply grease before initial startup.
