Browning 766961 2-bolt Flange Bearing 1.25 in Id

Product Description

The BROWNING 766961 is a 2-bolt flange bearing unit in the VF2B 200 series, designed to support rotating shafts in industrial and mechanical power transmission applications. The cast iron housing accepts a 1.25-inch bore and uses a concentric collar lock to secure the shaft. It delivers a static load capacity of 3,493 pounds and a dynamic load capacity of 5,782 pounds, making it well-suited for moderate-to-heavy duty conveyor, fan, pump, and material handling installations. The 52100 steel ball bearing insert requires lubrication. Installation is performed by millwrights, maintenance technicians, and industrial mechanics.

This flange bearing is used in fixed-mount applications where a shaft must be supported perpendicular to a mounting surface. The 2-bolt flange configuration simplifies mounting on frames, supports, and equipment bases. Typical applications include conveyor drives, blower shafts, auger systems, and general industrial machinery operating at speeds up to 4,000 RPM. The 5.125-inch bolt hole center-to-center spacing accommodates standard structural framing layouts, and the 0.5-inch bolt size is common in industrial fastener inventories.

Installation Notes

Installation is typically performed by qualified millwrights or maintenance mechanics following lockout/tagout (LOTO) procedures before working on any rotating equipment. Ensure the mounting surface is flat and the shaft is clean and free of burrs before seating the bearing. Torque mounting bolts evenly and verify shaft alignment before restoring power. Lubricate the bearing insert at initial startup and at regular service intervals per the equipment maintenance schedule.
