Browning 766473 4-bolt Flange Bearing 2-7/16 in Bore

Product Description

The BROWNING 766473 is a 4-bolt flange bearing unit in the VF4B 200 Series, designed to support rotating shafts in industrial and commercial drive applications. The unit accepts a 2-7/16 inch bore and uses a ball bearing insert made from 52100 steel, housed in a cast iron flange body. It carries a static load capacity of 8,150 pounds and a dynamic load capacity of 11,789 pounds, making it suitable for moderate-to-heavy radial load service. The concentric collar lock secures the bearing insert to the shaft. Licensed millwrights, maintenance mechanics, and industrial technicians are the primary installers of this type of unit.

This flange bearing unit is used in conveyor systems, fan and blower shafts, agricultural equipment, and general industrial machinery where a rigid 4-bolt mounting point is required. The cast iron housing provides rigidity in stationary mounting applications. The VF4B 200 Series is a standard industrial frame size, and this unit is suited for both new installations and direct replacement of worn flange bearings in comparable frame configurations. Maximum shaft speed is rated at 2,500 RPM. Lubrication is required during installation and as part of routine maintenance intervals.

Key Features

• 2-7/16 inch bore with concentric collar lock for positive shaft engagement
• 52100 steel ball bearing insert for durability under radial load
• Cast iron housing resists deformation under static and dynamic loading
• 8,150 lb static load capacity and 11,789 lb dynamic load capacity
• 4-bolt mounting pattern with 5-5/8 inch center-to-center bolt hole spacing
• Rated to 2,500 RPM maximum shaft speed

Compatibility

Designed as an OEM-style replacement or new-install flange bearing unit for industrial shaft applications requiring a 4-bolt flange mount with a 2-7/16 inch bore in the VF4B 200 Series frame.

Installation Notes

Installation is typically performed by qualified millwrights or maintenance mechanics. Shut down and lock out all power to the drive system before removing or installing any bearing units, following LOTO procedures per applicable safety standards. Do not use impact tools to seat the bearing insert onto the shaft. Lubricate the bearing through the grease fitting before commissioning and maintain lubrication intervals per the equipment service schedule.
