Browning 767148 2-bolt Flange Bearing 1 Inch Id

Product Description

The BROWNING 767148 is a 2-bolt flange bearing unit in the VF2S 300 Series, designed for securing rotating shafts in industrial and mechanical power transmission applications. It accepts a 1-inch inside diameter shaft and is built around a ball bearing insert made from 52100 steel, housed in a cast iron flange body. The bearing is locked to the shaft via a set screw. Static load capacity is 2,567 pounds and dynamic load capacity is 4,381 pounds, making it suitable for moderate-to-heavy radial load conditions. Lubrication is required during service. Licensed millwrights, maintenance mechanics, and industrial technicians are the primary installers.

This bearing unit fits applications where a 2-bolt flange mount is required to support a 1-inch shaft on equipment such as conveyors, fans, pumps, augers, and general machinery drives. The VF2S 300 Series is a standard industrial flange bearing configuration commonly used in both light industrial and commercial facility maintenance settings. The 4-19/32-inch center-to-center bolt hole spacing and 7/16-inch bolt size allow straightforward mounting to standard steel or fabricated frames.

Installation Notes

Installation is typically performed by a licensed millwright or qualified maintenance mechanic. De-energize and lock out all power to the equipment before removing or installing the bearing unit per LOTO procedures. Ensure the shaft is clean and free of burrs before sliding the bearing into position, then torque the set screw to the equipment manufacturer's specification. Apply grease through the lubrication fitting during initial installation and at intervals per the equipment maintenance schedule.
