Browning 767375 4-bolt Flange Bearing 1.25 in Id

Product Description

The BROWNING 767375 is a 4-bolt flange bearing unit designed for industrial and mechanical drive applications requiring a secure, rigid mount. Sold under the VF4E-220 series designation, this unit features a 1.25-inch bore with an eccentric lock collar for reliable shaft retention. It carries a static load capacity of 3,493 pounds and a dynamic load capacity of 5,782 pounds. The housing is cast iron, providing strength and vibration resistance in demanding environments. The 52100 steel insert delivers the hardness and fatigue resistance required for rotating shaft applications under continuous load. Maintenance technicians, millwrights, and HVAC equipment installers commonly specify this type of unit for fan shafts, conveyor drives, and blower assemblies.

This flange bearing is suited for residential and light commercial HVAC blower assemblies, industrial fan drives, conveyor systems, and general power transmission equipment where a 4-bolt mounting pattern is required. The 3.625-inch distance between mounting hole centers and the 4.625-inch overall length and height make it a direct-fit candidate for equipment originally specifying VF4E-220 series units. Installations requiring a 0.5-inch bolt size for the mounting pattern are supported by this housing design. This unit is appropriate wherever a cast iron 4-bolt flange with a 1.25-inch bore and eccentric locking is called for.

Key Features

• 1.25-inch bore with eccentric lock collar for positive shaft retention without set-screw damage
• 3,493-pound static load capacity and 5,782-pound dynamic load capacity for heavy-duty rotating shaft service
• Cast iron housing resists vibration and provides rigid support in blower and drive applications
• 52100 steel bearing insert for high hardness and extended fatigue life under continuous load
• 4-bolt mounting pattern with 3.625-inch center-to-center spacing and 0.5-inch bolt size for secure, stable installation
• Overall dimensions of 4.625 inches length by 4.625 inches height fit standard VF4E-220 mounting footprints

Compatibility

Designed as an OEM-style replacement flange bearing for equipment originally specifying VF4E-220 series 4-bolt flange units with a 1.25-inch bore and eccentric lock collar in cast iron housing.

Installation Notes

Installation should be performed by a qualified millwright, maintenance technician, or mechanical contractor. Disconnect and lock out all power to the drive system before removing or installing any bearing unit. Ensure the mounting surface is flat and clean before torquing the four mounting bolts to equipment manufacturer specifications. Do not over-tighten the eccentric lock collar; follow the bearing manufacturer's recommended locking procedure to avoid inducing shaft preload.
