Browning 766470 4-bolt Flange Bearing 2 in Id Cast Iron

Product Description

The BROWNING 766470 is a 4-bolt flange bearing unit in the VF4B 200 Series, designed for industrial and commercial mechanical drive applications. It features a 2-inch inside diameter bore with a concentric collar lock, housed in a cast iron body measuring 6-3/8 inches in overall length and 6-3/8 inches in overall height. The bearing insert is made from 52100 steel and requires lubrication. With a static load capacity of 6,601 pounds and a dynamic load capacity of 9,752 pounds, this unit is built for demanding shaft support tasks. A licensed millwright or mechanical technician typically installs this type of bearing in conveyor, fan, pump, and material-handling equipment.

This flange bearing is suited for use in commercial and light industrial machinery where a rigid 4-bolt mounting configuration is required. Typical installation scenarios include shaft support on belt-driven systems, blowers, and other rotating equipment operating at up to 2,500 RPM. The 5-1/8-inch center-to-center bolt hole spacing and 5/8-inch bolt size make hardware selection straightforward during mounting. The base-to-center distance of 1.375 inches and hub diameter of 5-1/4 inches accommodate standard mounting surfaces in these applications.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. De-energize and lock out all power sources before removing or installing any bearing unit. Ensure the mounting surface is flat and clean before securing the flange bolts, and verify shaft alignment before final torque. Lubricate the bearing insert per the equipment manufacturer's service interval before placing the unit in operation.
