Browning 767494 4-bolt Flange Bearing 1-7/16 in Bore

Product Description

The BROWNING 767494 is a VF4S-300 series 4-bolt flange bearing unit designed for shaft support in industrial and commercial power transmission applications. The cast iron housing accepts a 1-7/16 inch bore with a 52100 steel ball bearing insert locked in place by a set screw. Static load capacity is 4,467 pounds and dynamic load capacity is 7,340 pounds, making this unit suitable for moderate-to-heavy radial load applications. Lubrication is required during installation and at regular service intervals. This bearing is installed by millwrights, maintenance technicians, and mechanical contractors on conveyor systems, fans, pumps, and similar rotating equipment.

This 4-bolt flange unit fits standard industrial mounting surfaces with 4 inch center-to-center bolt hole spacing using 1/2 inch bolts. The overall length and overall height are each 5-1/8 inches. Maximum rated speed is 3,500 RPM. Typical applications include HVAC fan assemblies, material handling conveyors, agricultural equipment drives, and light-to-medium industrial machinery where a rigid four-bolt mounting configuration is required for shaft alignment and load management.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. De-energize and lock out all power to the driven equipment before removing or installing bearing units, following applicable OSHA lockout/tagout procedures. Ensure the mounting surface is flat and clean before torquing the four flange bolts evenly. This bearing requires grease lubrication at initial installation and per the equipment manufacturer's maintenance schedule — do not operate dry.
