Browning 767692 4-bolt Flange Bearing 1-3/4 Inch Bore

Product Description

The BROWNING 767692 is a 4-bolt flange bearing unit in the VF4S 200 series, designed for industrial shaft support applications requiring a rigid, bolted mounting configuration. This unit features a 1-3/4 inch bore with a set screw lock and houses a 52100 steel ball bearing insert in a cast iron flange housing. The unit carries a static load capacity of 5,139 pounds and a dynamic load capacity of 7,901 pounds, making it suited for moderate-to-heavy radial load applications. Lubrication is required for proper service life. Millwrights, maintenance technicians, and industrial equipment installers work with this type of bearing unit in conveyor, fan, pump, and general power transmission systems.

This bearing unit fits applications calling for a 4-bolt flange mount where the shaft diameter is 1-3/4 inches. The cast iron housing provides rigidity in fixed-mount installations on equipment frames and support structures. With a maximum rated speed of 3,000 RPM, it is appropriate for moderate-speed drive and conveyor shaft applications in manufacturing, material handling, and agricultural equipment. Install center-to-center bolt hole spacing of 4-1/8 inches must be confirmed at the mounting surface before installation.

Compatibility

Designed as an OEM-style replacement or direct-fit 4-bolt flange bearing unit for industrial shafts with a 1-3/4 inch diameter, using the VF4S 200 series mounting footprint with 4-1/8 inch bolt hole center spacing and 9/16 inch bolt size.

Installation Notes

Installation is typically performed by millwrights or qualified maintenance technicians. De-energize and lock out all connected drive equipment before handling the bearing unit. Confirm shaft diameter, bolt hole pattern, and center-to-center spacing match the mounting surface before pressing or seating the unit. Set screws must be torqued to the fastener manufacturer specification for the screw size used, and the bearing should be lubricated per the equipment manufacturer interval after installation.
