Browning 767383 4-bolt Flange Bearing 1-7/16 Bore

Product Description

The BROWNING 767383 is a 4-bolt flange bearing unit from the VF4E 200 series, designed for mounted power transmission applications in industrial and mechanical systems. The unit features a 1-7/16 inch bore with an eccentric lock collar, a cast iron housing, and a 52100 steel ball bearing insert. It carries a static load capacity of 3,493 pounds and a dynamic load capacity of 5,782 pounds, making it suited for moderate-to-heavy radial load service. The overall length and height are each 4-5/8 inches. Licensed millwrights, maintenance mechanics, and equipment technicians typically install this type of bearing unit on shaft-driven equipment such as fans, conveyors, and pumps.

This 4-bolt flange bearing is used wherever a rigid, four-point-mounted bearing housing is required to support a rotating shaft in a fixed plane. Typical applications include HVAC fan assemblies, blower systems, conveyor drive shafts, and light industrial machinery. The eccentric lock design allows the bearing insert to be secured directly to the shaft without a keyway. Lubrication is required during installation and at regular service intervals per equipment OEM recommendations.

Key Features

• 1-7/16 inch bore accommodates standard shaft sizes in the VF4E 200 series range
• Eccentric lock collar secures insert to shaft without a keyway
• Cast iron housing provides rigid, corrosion-resistant mounting support
• 52100 steel ball bearing insert rated for static loads up to 3,493 pounds and dynamic loads up to 5,782 pounds
• Maximum operating speed of 4,000 RPM
• Four 1/2 inch mounting bolts on 3-5/8 inch center-to-center spacing for secure flange attachment

Compatibility

Designed as an OEM-style replacement or direct-fit bearing unit for applications requiring a 4-bolt flange mount with a 1-7/16 inch bore shaft and 3-5/8 inch bolt hole center-to-center spacing, consistent with VF4E 200 series dimensional standards.

Installation Notes

Installation should be performed by a qualified millwright or maintenance mechanic. Shut down and lock out all power to the driven equipment before removing or installing any bearing unit. Ensure the shaft is clean and free of burrs before seating the insert and tightening the eccentric collar. Apply appropriate grease to the bearing insert prior to initial startup, and follow a scheduled re-lubrication interval based on operating conditions and load.
