Browning 766963 2-bolt Flange Bearing 1-7/16 Inch Id

Product Description

The BROWNING 766963 is a 2-bolt flange bearing unit designed to support rotating shafts in industrial and commercial power transmission applications. It accepts a 1-7/16 inch shaft bore and uses a concentric collar lock to secure the bearing insert to the shaft without set screws. The cast iron housing provides rigid support under both radial and thrust loads. Static load capacity is rated at 3,493 pounds and dynamic load capacity is rated at 5,782 pounds. The insert material is 52100 steel, a through-hardened bearing steel well suited for moderate-speed, high-load duty. Licensed millwrights, maintenance mechanics, and industrial technicians typically install this type of unit.

This flange bearing is suited for general industrial machinery, conveyor systems, agricultural equipment, blower assemblies, and similar power transmission setups where a 2-bolt flange mount is specified. The 2-bolt flange configuration allows installation on flat surfaces such as equipment frames, mounting plates, and structural steel. The 5-1/8 inch distance between mounting hole centers and 1/2 inch bolt size align with standard bolt patterns found on a wide range of industrial equipment frames.

Compatibility

Designed as an OEM-style replacement or direct installation 2-bolt flange bearing for industrial and commercial power transmission shafts with a 1-7/16 inch diameter.

Installation Notes

Installation should be performed by a qualified millwright or maintenance mechanic with the driven equipment fully de-energized and locked out per OSHA lockout/tagout procedures. Ensure the mounting surface is flat and clean before torquing the flange bolts to the equipment frame. Align the bearing with the mating bearing or shaft support before final tightening to prevent preload on the insert. Lubricate the bearing insert per the manufacturer service interval before placing the unit into service.
