Browning 767962 4-bolt Flange Bearing 2-3/16 in Id

Product Description

The BROWNING 767962 is a VF4S-135 series 4-bolt flange bearing unit designed for industrial rotating equipment that demands reliable radial load support. The cast iron housing encloses a 52100 steel ball bearing insert with a 2-3/16 inch bore, secured by a set screw lock. It carries a static load capacity of 6,601 pounds and a dynamic load capacity of 9,752 pounds, making it well-suited for moderate-to-heavy duty shaft applications. The unit measures 6-3/8 inches in overall length and 6-3/8 inches in overall height, with a hub diameter of 5-1/4 inches. Licensed millwrights, maintenance mechanics, and industrial technicians typically install and service this type of unit.

This flange bearing unit is used in industrial and commercial machinery installations where a shaft must be supported at a fixed mounting point. The 4-bolt flange configuration allows rigid attachment to equipment frames and base plates. With a maximum rated speed of 1,750 RPM and a bolt hole center-to-center distance of 5-1/8 inches, it fits into standard VF4S-series mounting layouts. Common applications include conveyor drives, fans, pumps, and other process equipment requiring consistent shaft alignment and periodic re-lubrication.

Key Features

• 2-3/16 inch bore accepts standard shaft sizes in VF4S-135 applications
• Cast iron housing provides durability in industrial environments
• 52100 steel ball bearing insert delivers high static and dynamic load capacity
• Set screw lock type secures the insert to the shaft without requiring a keyed shaft end
• 4-bolt flange mount with 5-1/8 inch bolt hole centers allows rigid frame installation
• Re-lubrication required — grease fitting access supports scheduled maintenance intervals

Compatibility

Designed as an OEM-style replacement or direct-fit bearing unit for applications requiring a VF4S-135 4-bolt flange bearing with a 2-3/16 inch inside diameter and 5-1/8 inch bolt hole center spacing.

Installation Notes

Installation should be performed by a qualified millwright or maintenance mechanic. Isolate and lock out all energy sources on the drive system before removing or installing the bearing unit. Verify shaft diameter, bolt pattern, and base-to-center height match the mounting surface before final torque. Lubrication is required at installation and on a scheduled basis thereafter — do not run the unit dry.
