Browning 766964 2-bolt Flange Bearing 1.5 Inch Id Cast Iron

Product Description

The BROWNING 766964 is a 2-bolt flange bearing unit designed for industrial shaft mounting applications requiring a rigid, cast iron housing and a secure concentric collar lock. The bearing accepts a 1.5-inch shaft ID and delivers a static load capacity of 4,467 pounds and a dynamic load capacity of 7,340 pounds, making it suitable for moderate-to-heavy radial load applications. The 52100 steel insert provides the hardness and fatigue resistance expected in demanding rotational service. Overall length is 6.75 inches and overall height is 4.125 inches. This unit is installed by millwrights, industrial maintenance technicians, and mechanical contractors.

This flange bearing is used in industrial and commercial equipment where a 2-bolt mounting pattern is required and space or structural constraints favor a flange-style over a pillow block. Typical applications include conveyor drives, fan shafts, pump mounts, and general power transmission assemblies. The 5-21/32-inch distance between mounting hole centers and the 0.5-inch bolt size allow for direct bolt-up to standard fabricated or OEM steel frames. The concentric collar lock secures the shaft without the need for a set-screw arrangement that can damage shaft surfaces.

Key Features

• 1.5-inch bore ID accepts standard shaft sizes with concentric collar lock retention
• Static load capacity of 4,467 pounds and dynamic load capacity of 7,340 pounds
• Cast iron housing for rigidity and vibration damping in industrial environments
• 52100 steel bearing insert for high hardness and fatigue resistance
• 2-bolt mounting pattern with 5-21/32-inch hole center spacing and 0.5-inch bolt size
• Overall dimensions of 6.75 inches length by 4.125 inches height suit standard mounting clearances

Compatibility

Designed as an OEM-style replacement or new-installation 2-bolt flange bearing for industrial power transmission shafts with a 1.5-inch diameter.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. De-energize and lock out all drive equipment before removing or installing bearing units, following OSHA lockout/tagout procedures. Ensure the mounting surface is flat and clean to prevent housing distortion under load. Do not overtighten mounting bolts beyond the equipment manufacturer's specified fastener torque for the frame material; engage the concentric collar lock only after the shaft is positioned and aligned.
