Browning 767423 4-bolt Flange Bearing 2 Inch Id Cast Iron

Product Description

The BROWNING 767423 is a 4-bolt flange bearing unit in the VF4S 200 series, designed for shaft support in industrial and commercial power transmission applications. Built around a 2-inch inside diameter ball bearing insert made from 52100 steel, this unit features a cast iron housing measuring 6-3/8 inches overall length by 6-3/8 inches overall height. The bearing insert is secured via a set screw lock and requires periodic lubrication. With a static load capacity of 6,601 pounds and a dynamic load capacity of 9,752 pounds, it is rated for up to 2,500 RPM. Millwrights, maintenance technicians, and industrial mechanics install this unit on rotating shaft assemblies in conveyors, fans, pumps, and similar driven equipment.

This bearing unit is suited for mounting in fixed-position shaft support applications where a rigid 4-bolt flange mount is required. The cast iron housing provides durability in demanding plant environments. Typical installations include conveyor drive shafts, blower assemblies, agricultural equipment, and general industrial machinery where a 2-inch shaft diameter is present. The 5-1/8-inch bolt hole center-to-center spacing and 5/8-inch bolt size simplify fit-up to standard mounting plates and frames.

Installation Notes

Installation should be performed by a qualified millwright or maintenance mechanic. De-energize and lock out all power to the drive system before removing or installing bearing units, following LOTO procedures per applicable safety standards. Ensure the mounting surface is flat and the shaft is clean and free of burrs before seating the bearing. Torque mounting bolts evenly in a cross pattern and verify set screws are properly tightened against the shaft before returning the assembly to service. Lubricate the bearing insert per the manufacturer interval before initial startup.
