Browning 766959 2-bolt Flange Bearing 1-3/16 Inch Id

Product Description

The BROWNING 766959 is a 2-bolt flange bearing unit designed to support rotating shafts in industrial and mechanical power transmission applications. The bearing accepts a 1-3/16 inch shaft bore and uses a concentric collar lock to secure the shaft without set screws, reducing shaft damage during installation. The cast iron housing delivers 2,567 pounds of static load capacity and 4,381 pounds of dynamic load capacity, making it well suited for moderate to heavy radial load service. The 52100 steel insert provides hardness and wear resistance appropriate for continuous-duty rotating equipment. Licensed millwrights, maintenance mechanics, and industrial equipment technicians are the primary installers.

This flange bearing is commonly installed in conveyor systems, agricultural equipment, fans, blowers, and general industrial machinery where a two-bolt mounting pattern is preferred for simplified field alignment. The 2-bolt flange configuration allows the unit to be surface-mounted to a flat structural member. The 4-19/32 inch distance between mounting hole centers determines the bolt pattern layout on the mounting surface. Confirm shaft diameter and load requirements before installation in any new or replacement application.

Key Features

• 1-3/16 inch bore ID with concentric collar lock for secure, low-damage shaft retention
• Cast iron housing for durability in industrial environments
• 52100 steel bearing insert for hardness and extended wear life
• 2,567 pounds static load capacity and 4,381 pounds dynamic load capacity
• 2-bolt flange mount with 4-19/32 inch center-to-center bolt spacing
• Overall length of 5-9/16 inches and overall height of 3-1/8 inches for compact fitment

Compatibility

Designed as an OEM-style replacement or direct installation 2-bolt flange bearing for rotating shaft assemblies requiring a 1-3/16 inch bore with concentric collar locking and a standard 2-bolt flange mounting pattern.

Installation Notes

Installation should be performed by a qualified maintenance mechanic or millwright with the driven equipment fully de-energized and locked out per OSHA lockout/tagout procedures before any bearing work begins. Ensure the mounting surface is flat and clean before torquing the mounting bolts to avoid housing distortion. The concentric collar lock should be tightened in the direction of shaft rotation after the shaft is seated fully in the bore. Do not use impact tools to drive the bearing onto the shaft.
