Browning 767997 4-bolt Flange Bearing 2-7/16 Inch Bore

Product Description

The BROWNING 767997 is a 4-bolt flange bearing unit in the VF4S 200 series, designed for industrial shaft support applications requiring a rigid, bolted housing mount. The unit features a 2-7/16 inch bore with a set screw lock and a cast iron housing, giving it the structural rigidity needed for moderate-to-heavy radial load service. It carries a static load capacity of 8,150 pounds and a dynamic load capacity of 11,789 pounds, making it well suited for conveyor drives, fans, pumps, and similar rotating equipment. The 52100 steel bearing insert and required-lubrication design are standard for this class of industrial flange unit. Licensed trades and industrial maintenance technicians are the primary installers.

This flange unit fits applications where a 4-bolt square flange mount is specified and shaft diameter is 2-7/16 inches. Typical installations include conveyor head and tail shafts, aggregate processing equipment, agricultural drives, and industrial fan shafts operating at up to 2,500 RPM. The overall length and height of 6-7/8 inches each, combined with a 5-5/8 inch center-to-center bolt pattern, match standard VF4S 200 series mounting footprints. The 5/8 inch bolt size should be confirmed against the mounting surface specification before installation.

Compatibility

Designed as an OEM-style replacement or direct-fit unit for applications requiring a VF4S 200 series 4-bolt flange bearing with a 2-7/16 inch bore and a 5-5/8 inch bolt hole center-to-center dimension.

Installation Notes

Installation is typically performed by industrial maintenance mechanics or millwrights. Shut down and lock out the drive system completely before removing the worn unit or seating the replacement. Torque mounting bolts evenly in a cross pattern to the specification listed for the 5/8 inch bolt size per applicable mechanical standards. This bearing requires lubrication at commissioning and on a scheduled interval thereafter — refer to the manufacturer service documentation for grease type and relubrication frequency.
