Browning 767904 4-bolt Flange Bearing 1 Inch Id Cast Iron

Product Description

The BROWNING 767904 is a 4-bolt flange bearing unit from the VF4S 300 Series, designed for industrial shaft support applications requiring a secure, rigid mount. The unit accepts a 1 inch shaft with a set screw lock and houses a ball bearing insert made from 52100 steel. It carries a static load capacity of 2,567 pounds and a dynamic load capacity of 4,381 pounds. The cast iron housing provides durability in demanding environments. Maximum operating speed is 4,500 RPM. Licensed millwrights, maintenance technicians, and industrial mechanics are the typical installers of this unit.

This flange bearing is suited for light-to-medium industrial equipment including conveyors, fans, pumps, and material handling systems where a 4-bolt flange mount is required. The VF4S 300 Series is designed for installations where the bearing must be secured to a flat mounting surface with four bolts at a center-to-center distance of 3.25 inches. The overall length and height are each 4.25 inches, making it a compact, square-footprint unit appropriate for space-constrained equipment frames. Lubrication is required and must be maintained per the equipment service schedule.

Installation Notes

Installation is typically performed by licensed millwrights or qualified maintenance technicians. De-energize and lock out all power to the equipment before removing the existing bearing or mounting the new unit. Verify shaft diameter and confirm bolt hole pattern matches the mounting surface before installation. Lubrication is required at initial installation and at regular service intervals — use the grease type and interval specified by the equipment manufacturer.
