Browning 767655 4-bolt Flange Bearing 1.5 Inch Bore Cast Iron

Product Description

The BROWNING 767655 is a 4-bolt flange bearing unit in the VF4E 200 Series, designed to support rotating shafts in fixed-mount industrial and mechanical drive applications. It houses a ball bearing insert made from 52100 steel and is locked to the shaft via an eccentric lock collar. The cast iron housing provides durability under load. Static load capacity is rated at 4,467 pounds and dynamic load capacity reaches 7,340 pounds, making this unit suitable for moderate-to-heavy radial loads. Maximum operating speed is 3,500 RPM. The unit accepts a 1.5-inch bore shaft and requires periodic lubrication to maintain bearing life.

This bearing unit is used in conveyor drives, fan assemblies, pump mounts, and general industrial equipment where a rigid, four-point flange mount is needed. The 4-inch bolt hole center-to-center spacing and 1/2-inch bolt size suit standard mounting patterns in both new builds and replacement installations. The VF4E 200 Series is commonly specified in light manufacturing, agricultural equipment, and HVAC fan applications requiring a compact, serviceable flange unit. Installers work with standard hand tools and mounting hardware. The eccentric lock system does not require a keyed shaft, simplifying shaft preparation.

Installation Notes

Installation should be performed by a qualified mechanical or industrial technician. Shut down and lock out all power to the drive system before mounting or removing the bearing unit. Align the flange squarely to the mounting surface before torquing the 1/2-inch mounting bolts to prevent housing distortion. After installation, lubricate the bearing insert through the grease fitting before returning the unit to service.
