Browning 767401 4-bolt Flange Bearing 5/8 Inch Id

Product Description

The BROWNING 767401 is a 4-bolt flange bearing unit in the VF4S 200 Series, designed for secure shaft support in industrial and mechanical drive applications. The bearing features a 5/8-inch bore with a ball insert made from 52100 steel, housed in cast iron for durability under load. It carries a static load capacity of 1,444 pounds and a dynamic load capacity of 2,611 pounds, making it well-suited for moderate-to-heavy radial load conditions. Set screw locking secures the shaft, and the unit requires periodic lubrication to maintain rated performance. HVAC, mechanical, and industrial equipment technicians typically handle installation of flange bearings in this class.

This bearing is used in belt-driven fan assemblies, blower shafts, conveyor drives, and similar rotating equipment found in commercial HVAC systems, industrial ventilation, and light mechanical applications. The 4-bolt mounting pattern provides stable, rigid support in both horizontal and vertical mount orientations. The 5/8-inch inside diameter suits common fractional-inch shaft sizes used in blower wheels and fan assemblies across commercial and light industrial equipment.

Key Features

• 5/8-inch bore with set screw shaft lock for secure, positive shaft retention

• Cast iron housing provides rigid support and resistance to deflection under load
• 1,444 lb static and 2,611 lb dynamic load capacity rated for moderate-to-heavy applications
• Maximum rated speed of 7,500 RPM suitable for typical fan and blower shaft speeds
• 4-bolt flange mount with 2-1/8-inch bolt hole center-to-center spacing for straightforward panel or bracket mounting

Compatibility

Designed as an OEM-style replacement or direct-fit flange bearing for equipment requiring a 4-bolt flange unit with a 5/8-inch bore in the VF4S 200 Series configuration.

Installation Notes

Installation should be performed by a qualified mechanical or HVAC technician. De-energize and lock out the equipment before removing or installing any bearing unit. Ensure the shaft is clean and free of burrs before seating the bearing, and torque the mounting bolts evenly to prevent housing distortion. Lubricate the bearing insert per the equipment manufacturer's service interval before returning the unit to service.
