Browning 767868 4-bolt Flange Bearing 1-11/16 in Id

Product Description

The BROWNING 767868 is a VF4S-127 series 4-bolt flange bearing unit designed for industrial shaft support applications. The unit features a 1-11/16 inch bore and a cast iron housing with an inserted 52100 steel ball bearing element. It carries a static load capacity of 5,139 pounds and a dynamic load capacity of 7,901 pounds, making it suitable for moderate-to-heavy duty rotating equipment. The set screw lock secures the bearing insert to the shaft. Overall dimensions are 5-3/8 inches in length and 5-3/8 inches in height. The unit weighs 5.24 pounds. Installation is typically performed by millwrights, maintenance mechanics, or industrial technicians working on conveyor systems, fans, pumps, and similar belt-driven or direct-drive equipment.

This 4-bolt flange unit is used in industrial and commercial settings where a rigid, square-mount bearing housing is required. Common applications include conveyor drives, agricultural equipment, material handling systems, HVAC fan shafts, and light manufacturing machinery. The 4-bolt mounting pattern and cast iron housing provide a stable, rigid mount on flat surfaces. The bearing requires periodic lubrication through the grease fitting. Maximum operating speed is 2,000 RPM. This unit is part of the VF4S 100 series.
