Browning 767815 4-bolt Flange Bearing 1-1/4 in Id

Product Description

The BROWNING 767815 is a 4-bolt flange bearing unit designed to support rotating shafts in industrial and mechanical drive applications. It accepts a 1-1/4 inch shaft and secures the insert via a set screw lock. The bearing insert is manufactured from 52100 steel and housed in a cast iron flange body. With a static load capacity of 2,567 pounds and a dynamic load capacity of 4,381 pounds, this unit is built for demanding continuous-duty applications. Overall dimensions are 4-1/4 inches in length and 4-1/4 inches in height. The unit ships individually and is a direct-mount replacement for standard 4-bolt flange configurations.

This flange bearing is suited for use in conveyor systems, fan assemblies, agricultural equipment, industrial machinery, and other power transmission setups where a rigid 4-bolt mount is required. It is typically installed by millwrights, maintenance mechanics, or industrial technicians as part of a shaft support or drive system. The 3-1/4 inch distance between mounting hole centers simplifies bolt pattern alignment on standard equipment frames. The cast iron housing provides durability in light to moderate contamination environments.

Compatibility

Designed as an OEM-style replacement for standard 4-bolt flange bearing units with a 1-1/4 inch bore diameter in industrial and mechanical drive applications.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with power transmission components. Shut down and lock out all power to the equipment before removing or installing the bearing unit. Align the shaft carefully to avoid side loading the insert during installation. Set screws should be tightened to the shaft per standard mechanical practice using the appropriate hex key.
