Browning 767928 4-bolt Flange Bearing 1-11/16 in Cast Iron

Product Description

The BROWNING 767928 is a 4-bolt flange bearing unit designed to support rotating shafts in industrial and mechanical power-transmission applications. It accepts a 1-11/16 inch bore diameter and features an eccentric lock collar for secure shaft retention. The cast iron housing provides rigid support under load, with a static load capacity of 5,139 pounds and a dynamic load capacity of 7,901 pounds. The insert is manufactured from 52100 steel, a bearing-grade alloy known for its hardness and fatigue resistance. This unit is installed by millwrights, maintenance mechanics, and industrial equipment technicians wherever a flanged bearing mount is required.

This flange bearing unit is suited for use in conveyors, fans, blowers, and general industrial machinery where shaft support must be mounted to a flat surface using a 4-bolt pattern. The overall length and height are both 5-3/8 inches, making it a square-footprint unit that fits standard flange-mount applications. The 4-1/8 inch distance between mounting hole centers and 9/16 inch bolt size align with common industrial mounting configurations. It is appropriate for both new installations and direct replacement of worn or failed flange units of equivalent bore and bolt pattern.

Key Features

• 1-11/16 inch bore ID accommodates common industrial shaft sizes

• Cast iron housing offers rigid, vibration-resistant mounting
• 52100 steel insert for high hardness and load durability
• 5,139 lb static and 7,901 lb dynamic load capacity for demanding service conditions
• 4-bolt mounting pattern with 9/16 inch bolt size and 4-1/8 inch hole center spacing

Compatibility

Designed as an OEM-style replacement or new-installation flange bearing for industrial power-transmission systems requiring a 4-bolt flange unit with a 1-11/16 inch bore and eccentric lock.

Installation Notes

Installation should be performed by a qualified millwright or maintenance mechanic. De-energize and lock out all power to the driven equipment before removing or installing the bearing unit. Ensure the mounting surface is flat and clean before torquing the mounting bolts, and verify shaft alignment before final tightening. Do not hammer directly on the bearing housing during installation.
