Browning 767320 4-bolt Flange Bearing 1.5 Inch Id Cast Iron

Product Description

The BROWNING 767320 is a cast iron 4-bolt flange bearing unit from the VF4E 100 series, designed to support rotating shaft applications in industrial and mechanical equipment. It carries a 1.5-inch bore, accommodates a 52100 steel ball bearing insert, and delivers a static load capacity of 4,467 pounds and a dynamic load capacity of 7,340 pounds. The eccentric lock design secures the bearing insert to the shaft without set screws against the shaft surface. Licensed millwrights, maintenance mechanics, and industrial equipment technicians install this unit in conveyor systems, fans, pumps, and general power transmission assemblies.

This flange bearing is suited for medium-duty rotating equipment found in manufacturing plants, agricultural machinery, and HVAC fan assemblies. The 4-bolt mount pattern provides a stable, rigid connection to steel or fabricated mounting plates. With a maximum rated speed of 2,500 RPM and a base-to-center distance of 1.281 inches, it fits standard shaft layouts where a compact flange mount is required. The VF4E 100 series is sized for 1.5-inch diameter shafts and accepts standard 0.5-inch mounting bolts.

Installation Notes

Installation is performed by licensed millwrights or qualified maintenance technicians. De-energize and lock out all power to the driven equipment before removing or installing any bearing unit. Align the shaft carefully before tightening the 0.5-inch mounting bolts to prevent premature wear. Lubricate the bearing insert according to the manufacturer service interval before putting the unit into service.
