Browning 766233 4-bolt Flange Bearing 1-7/16 Inch Bore

Product Description

The BROWNING 766233 is a 4-bolt flange bearing unit designed for use in industrial and mechanical drive applications where shaft support and load handling are required. This unit features a 1-7/16 inch bore with a concentric collar lock for secure shaft engagement. The cast iron housing provides durability in demanding environments. With a static load capacity of 4,467 pounds and a dynamic load capacity of 7,340 pounds, this bearing is suited for moderate-to-heavy duty installations. The 52100 steel insert offers reliable wear resistance. This unit is typically installed by millwrights, maintenance mechanics, or industrial technicians working on conveyor systems, fans, blowers, and similar rotating equipment.

This bearing unit is appropriate for use in a wide range of commercial and industrial applications including HVAC fan shafts, conveyor drive systems, and general power transmission equipment. The 4-bolt mounting pattern provides a stable, rigid connection to equipment frames and supports accurate shaft alignment. The overall length and height of 4-5/8 inches each, combined with the 3-5/8 inch distance between mounting hole centers, make this unit compatible with standard bolt patterns found in common industrial equipment frames.

Compatibility

Designed as an OEM-style replacement or direct-fit 4-bolt flange bearing for industrial and mechanical drive applications requiring a 1-7/16 inch bore with concentric collar locking and standard 4-bolt mounting geometry.

Installation Notes

Installation should be performed by a qualified millwright or maintenance mechanic. De-energize and lock out all power to the drive system before removing or installing bearing units. Ensure the mounting surface is flat and clean before seating the flange, and verify shaft alignment before fully torquing the mounting bolts. Collar lock should be engaged only after the unit is positioned correctly on the shaft.
