Browning 767670 Tapped Base Pillow Block Bearing 1.5 in

Product Description

The BROWNING 767670 is a tapped base pillow block bearing in the VTBS 200 series, designed for industrial shaft support applications requiring a reliable, bolt-down mounted bearing unit. It accepts a 1.5-inch bore diameter with a straight bore and set screw locking mechanism. The housing is cast iron and the insert is made from 52100 bearing steel, delivering durability under sustained radial loading. With a static load capacity of 4,467 pounds and a dynamic load capacity of 7,340 pounds, this unit handles demanding mechanical drive and conveyor applications. Mechanical trades and industrial maintenance technicians install this bearing as part of shaft support assemblies in power transmission systems.

This bearing is suited for use in industrial machinery, conveyor systems, agricultural equipment, and other shaft-driven mechanical assemblies requiring a two-bolt tapped base mount. The VTBS 200 series configuration provides a low-profile base with a 3.5-inch center-to-center bolt hole spacing, making it compatible with standard mounting pad layouts. Maximum operating speed is 3,500 RPM. The cast iron housing resists deformation under high static loads, and the 52100 bearing steel insert provides consistent performance across typical ambient operating conditions in general industrial environments.

Key Features

• 1.5-inch straight bore with set screw locking for secure shaft retention
• 4,467 lb static load capacity and 7,340 lb dynamic load capacity
• Cast iron housing for rigidity and resistance to deformation under load
• 52100 bearing steel insert for reliable rolling element performance
• Two-bolt tapped base mount with 3.5-inch center-to-center bolt spacing
• Rated to 3,500 RPM maximum operating speed

Compatibility

Designed as an OEM-style replacement or new-installation tapped base pillow block bearing for industrial shaft support assemblies requiring a 1.5-inch bore, two-bolt mount, and VTBS 200 series dimensional envelope.

Installation Notes

Installation is typically performed by industrial maintenance mechanics or millwrights. Shut down and lock out all drive power before handling or mounting the bearing unit. Ensure the mounting surface is flat and clean before securing the two-bolt base to prevent housing distortion. Set screw locking should be applied to a properly sized and finished shaft in accordance with the equipment manufacturer's specifications and applicable ANSI standards.
