Browning 767338 4-bolt Flange Bearing 1-7/16 in Bore

Product Description

The BROWNING 767338 is a VF4E-series 4-bolt flange bearing unit designed for industrial power transmission applications. It features a 1-7/16 inch bore with an eccentric lock collar and a cast iron housing. The bearing insert is made from 52100 steel and requires lubrication. Static load capacity is 3,493 pounds and dynamic load capacity is 5,782 pounds. Overall length and height are each 4-5/8 inches, and the unit weighs 3.66 pounds. This bearing is installed by maintenance mechanics, millwrights, and industrial technicians in conveyor, fan, pump, and shaft-support applications.

The VF4E-123 is suited for light-to-medium industrial equipment where a rigid, four-point mounting is required. Common applications include material handling conveyors, agricultural equipment, HVAC fan shaft assemblies, and general machinery drives. The 4-bolt flange pattern provides stable, balanced support for rotating shafts operating at up to 2,500 RPM. The eccentric locking collar allows secure shaft retention without set screws that can damage shaft surfaces.

Installation Notes

Installation should be performed by a qualified millwright or maintenance technician. De-energize and lock out all power to the drive system before mounting or removing the bearing unit. Align the housing to the shaft and mounting surface before tightening the 1/2 inch flange bolts to prevent housing distortion. Apply grease through the fitting before initial startup and follow the equipment manufacturer's lubrication interval schedule.
