Browning 767661 2-bolt Flange Bearing 1.5 Inch Id

Product Description

The BROWNING 767661 is a 2-bolt flange bearing unit designed for shaft support in industrial and mechanical drive applications. It carries a 1.5-inch bore (inside diameter) and is built around a 52100 steel insert housed in a cast iron flange body. The unit measures 6.75 inches overall length by 4.125 inches overall height, with mounting hole centers spaced 5.6875 inches apart. An eccentric lock collar secures the bearing to the shaft without requiring a set screw on the shaft itself. Static load capacity is rated at 4,467 pounds and dynamic load capacity at 7,340 pounds, making it well-suited for moderate-to-heavy duty conveyor, fan, and drive-shaft installations.

This flange bearing is used in a wide range of industrial settings including manufacturing lines, material handling systems, agricultural equipment, and HVAC fan assemblies. It is typically installed by millwrights, maintenance technicians, and mechanical contractors working on belt-driven or direct-coupled shaft arrangements. The 2-bolt mounting pattern simplifies alignment and replacement on existing bolt patterns, and the cast iron housing offers solid resistance to vibration and mechanical stress in fixed-mount configurations.

Compatibility

Designed as an OEM-style replacement or direct-fit flange bearing for industrial shaft applications requiring a 1.5-inch bore 2-bolt flange unit with eccentric locking.

Installation Notes

Installation should be performed by qualified millwrights or mechanical technicians. De-energize and lock out all connected drive equipment before beginning work per OSHA lockout/tagout procedures. Align the flange squarely to the mounting surface before tightening bolts to ensure even load distribution. Tighten the eccentric lock collar in the direction of shaft rotation to secure the bearing to the shaft.
