Browning 766960 2-bolt Flange Bearing 1-1/4 Inch Id

Product Description

The BROWNING 766960 is a 2-bolt flange bearing unit designed for industrial and mechanical drive applications where a reliable mounted bearing solution is required. This unit features a 1-1/4 inch bore with a cast iron housing and a 52100 steel insert, offering a static load capacity of 2,567 pounds and a dynamic load capacity of 4,381 pounds. The concentric collar lock secures the bearing to the shaft without set screws biting into the shaft surface. At 2 pounds, this unit is a compact, durable solution installed by millwrights, maintenance technicians, and mechanical contractors in conveyor, fan, pump, and general equipment applications.

This flange bearing is suited for light-to-medium industrial drive systems where a 2-bolt mounting configuration fits the equipment frame. It installs in both horizontal and vertical orientations depending on load requirements. The 4-19/32 inch distance between mounting hole centers and 5-9/16 inch overall length fit standard OEM and replacement mounting patterns commonly found in HVAC fan assemblies, agricultural equipment, material handling systems, and general power transmission equipment.

Key Features

• 1-1/4 inch inside diameter bore fits standard shaft sizes

• 52100 steel insert for high load capacity and fatigue resistance
• Concentric collar lock design for positive shaft retention without shaft damage
• Static load capacity of 2,567 pounds and dynamic load capacity of 4,381 pounds
• 2-bolt flange mount with 7/16 inch bolt size for straightforward installation

Compatibility

Designed as an OEM-style replacement or new-installation 2-bolt flange bearing for general power transmission and mechanical drive systems requiring a 1-1/4 inch bore and 2-bolt cast iron housing.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians. De-energize and lock out all power to the driven equipment before removing or installing the bearing. Align the housing squarely to the shaft and mounting surface before tightening fasteners to prevent premature wear. Verify shaft diameter and tolerance match the 1-1/4 inch bore specification before installation.
