Browning 767936 Tapped Base Pillow Block Bearing

Product Description

The BROWNING 767936 is a tapped base pillow block bearing unit designed for industrial shaft support applications. It carries the model designation VTBS-231 and features a 1-15/16 inch bore with a cast iron housing and a 52100 steel insert. The unit delivers a static load capacity of 5,216 pounds and a dynamic load capacity of 7,889 pounds, making it well suited for moderate-to-heavy radial load conditions. Locking is accomplished via a set screw arrangement. The overall assembly measures 5.5 inches in overall length and 4.625 inches in overall height. Licensed millwrights, maintenance mechanics, and industrial equipment technicians are the primary installers of this bearing unit.

This bearing is used in conveyor systems, fan shafts, pump drives, and general industrial machinery where a tapped base mounting configuration is required. The tapped base design allows the unit to be bolted directly to a machine frame or structural surface without the need for a separate mounting plate. It is appropriate for both original equipment installations and replacement service in light-to-medium industrial environments. The 4-inch distance between mounting hole centers simplifies alignment to standard bolt patterns common in industrial OEM equipment.

Key Features

• 1-15/16 inch bore diameter for direct shaft fit to standard fractional shaft sizes
• Static load capacity of 5,216 pounds and dynamic load capacity of 7,889 pounds
• Cast iron housing provides rigid support and resistance to deflection under load
• 52100 steel bearing insert for durability under radial and axial loading
• Set screw locking mechanism for secure shaft attachment
• 4-inch mounting hole center distance aligns to common industrial bolt patterns

Compatibility

Designed as an OEM-style replacement or new-installation tapped base pillow block bearing for industrial shaft applications requiring a 1-15/16 inch bore and a 4-inch mounting hole center distance.

Installation Notes

Installation should be performed by a qualified millwright or maintenance mechanic. Disconnect and lock out all power to the driven equipment before removing or installing any bearing unit. Ensure the mounting surface is flat and free of debris before torquing fasteners, and verify shaft alignment after mounting to prevent premature wear. Do not hammer directly on the housing or bearing insert during installation.
