Browning 767498 4-bolt Flange Bearing 1.5 in Id Cast Iron

Product Description

The BROWNING 767498 is a 4-bolt flange bearing unit designed for shaft support in industrial and mechanical drive applications. It accepts a 1.5-inch inside diameter shaft, secured by a set screw lock configuration. The insert is manufactured from 52100 steel, a high-carbon chromium alloy known for its load-bearing durability. The housing is cast iron, providing rigid support in demanding environments. With a static load capacity of 5,139 pounds and a dynamic load capacity of 7,901 pounds, this unit is rated for substantial radial loads. Licensed mechanical contractors, millwrights, and equipment maintenance technicians are the typical installers for this type of flange unit.

This bearing is suited for use in conveyor systems, agricultural equipment, industrial fans, pump drives, and general power transmission machinery where a fixed, 4-bolt mounting pattern is required. The 4-bolt flange configuration provides a stable, square mounting footprint appropriate for both horizontal and vertical shaft orientations. Typical applications include light-to-heavy industrial settings where a permanently mounted, serviceable bearing block is needed at a drive point or idler location.

Key Features

• 1.5-inch inside diameter bore with set screw lock for secure shaft retention
• 5,139-pound static load capacity and 7,901-pound dynamic load capacity
• 52100 steel insert for high-strength, fatigue-resistant load handling
• Cast iron housing for rigid, corrosion-resistant mounting support
• 4-bolt flange mount with 4.125-inch distance between mounting hole centers
• 9/16-inch bolt size for standard fastener compatibility

Compatibility

Designed as an OEM-style replacement or new-installation flange bearing for industrial power transmission systems requiring a 1.5-inch bore, 4-bolt flange housing with set screw lock retention.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. De-energize and lock out all power to the drive system before removing or installing any bearing unit. Ensure the mounting surface is flat and clean before torquing the four mounting bolts evenly to prevent housing distortion. Do not use impact tools directly on the bearing housing during installation.
