Browning 767851 2-bolt Flange Bearing 1-1/4 Inch Id

Product Description

The BROWNING 767851 is a 2-bolt flange bearing unit designed to support rotating shafts in light-to-medium industrial and mechanical drive applications. It accepts a 1-1/4 inch shaft bore and uses an eccentric locking collar to secure the shaft without set screws biting into the shaft surface. The insert is manufactured from 52100 steel, a high-carbon chromium alloy known for fatigue resistance under radial load cycling. With a static load capacity of 2,567 pounds and a dynamic load capacity of 4,381 pounds, this unit handles sustained radial loads typical in fan drives, conveyor systems, and pump shaft support applications. Licensed HVAC and mechanical contractors, as well as industrial maintenance technicians, install this type of bearing unit during equipment assembly or scheduled bearing replacement.

This flange bearing is suited for residential and light commercial mechanical systems where a 2-bolt cast iron flange mount is specified. Typical applications include blower shaft support in air handling units, belt-driven fan assemblies, and general power transmission equipment. The 2-bolt mounting pattern fits housings with a 4-19/32 inch center-to-center bolt spacing. The cast iron housing provides rigidity and vibration damping in fixed-mount installations. This unit ships individually and carries a minimum order quantity of one.

Key Features

• 1-1/4 inch inside diameter accommodates standard shaft sizes common in HVAC blower and drive assemblies
• Eccentric lock collar secures shaft without requiring set-screw notching on the shaft surface
• 52100 steel insert rated for 2,567 pounds static and 4,381 pounds dynamic radial load capacity
• Cast iron housing delivers rigidity and damping in fixed-mount installations
• 2-bolt mounting pattern with 4-19/32 inch hole center spacing for straightforward bolt-up replacement
• Overall length of 5-9/16 inches and overall height of 3-1/8 inches fit standard flange bearing envelopes

Compatibility

Designed as an OEM-style replacement 2-bolt flange bearing for shaft diameters of 1-1/4 inches in belt-driven HVAC blower assemblies, conveyor drives, and general power transmission equipment requiring a cast iron eccentric-lock flange unit.

Installation Notes

Installation should be performed by a qualified mechanical or HVAC technician. Shut down and lock out all power to the drive system before removing the old bearing or mounting the new unit. Confirm shaft diameter, housing bolt pattern, and centerline alignment before torquing mounting fasteners. The eccentric locking collar should be engaged in the direction of shaft rotation and secured with the appropriate spanner or drift punch per standard bearing installation practice.
