Browning 766954 2-bolt Flange Bearing 3/4 Inch Id

Product Description

The BROWNING 766954 is a 2-bolt flange bearing unit designed for light-to-medium industrial shaft support applications. The bearing features a 3/4 inch bore and a cast iron housing, making it suitable for use in conveyor systems, agricultural equipment, fans, and general power transmission assemblies. The insert is manufactured from 52100 steel and secured with a concentric collar lock for reliable shaft retention. Overall length is 4-13/32 inches and overall height is 2-1/2 inches. Static load capacity is 1,444 pounds and dynamic load capacity is 2,611 pounds. Maintenance technicians and millwrights typically install this style of bearing during equipment builds or scheduled component replacement.

The BROWNING 766954 fits standard 2-bolt flange mounting configurations with 3/8 inch bolt holes and a mounting hole center distance of 3-17/32 inches. It is well-suited for residential and light commercial machinery, pump drives, blower shafts, and similar rotating equipment where a flanged mount is required. The concentric collar lock allows secure shaft attachment without the need for set screws that can mar shaft surfaces. This unit ships as a complete, ready-to-install assembly.

Installation Notes

Installation is typically performed by a millwright or maintenance technician. De-energize and lock out all power to the equipment before removing or installing the bearing unit. Ensure the mounting surface is flat and clean before torquing mounting bolts. Tighten the concentric collar lock only after the bearing is properly aligned on the shaft to avoid pre-loading the insert.
