Browning 767479 Tapped Base Bearing Unit 1-7/16 in Id

Product Description

The BROWNING 767479 is a tapped base bearing unit designed to support rotating shafts in industrial and mechanical drive applications. Built on a cast iron base with a 52100 steel insert, this unit accepts a 1-7/16 inch bore and secures to the shaft via a set screw locking mechanism. The overall height measures 3-3/4 inches with a base-to-center height of 1-7/8 inches, making it suitable for standard mounting configurations. With a static load capacity of 3,493 pounds and a dynamic load capacity of 5,782 pounds, it is rated for demanding continuous-duty installations. Mechanical contractors and maintenance technicians install this unit in conveyor systems, fan drives, and other rotating equipment.

This tapped base bearing unit is used in industrial, commercial, and light manufacturing settings where a bolted-down pillow block style support is required for a shaft-driven assembly. The 3-1/4 inch between-mounting-hole-center dimension simplifies bolt-pattern alignment during installation. The cast iron housing provides durability in environments with vibration or moderate shock loading. It is a direct-mount solution for applications where the bearing must be positioned at a fixed height relative to the mounting surface.

Key Features

• 1-7/16 inch bore ID accommodates standard shaft diameters in drive and conveyor applications
• Set screw locking mechanism secures bearing to shaft without requiring a keyed bore
• Cast iron housing with 52100 steel insert for strength and wear resistance
• Static load capacity of 3,493 pounds and dynamic load capacity of 5,782 pounds
• 3-1/4 inch between mounting hole centers for straightforward bolt-pattern alignment
• Base-to-center height of 1-7/8 inches supports precise shaft elevation control

Compatibility

Designed as an OEM-style replacement or direct installation tapped base bearing unit for industrial rotating shaft assemblies requiring a 1-7/16 inch bore and a bolted mounting configuration.

Installation Notes

Installation should be performed by a qualified mechanical or maintenance technician. Disengage and lock out all power to the driven equipment before mounting or removing the bearing unit. Ensure the mounting surface is flat and clean before torquing fasteners, and align the shaft carefully before tightening set screws to avoid premature wear. Follow all applicable machinery safety standards and the equipment manufacturer guidelines for bearing replacement.
