Browning 767882 Pillow Block Bearing 1-11/16 in Id Cast Iron

Product Description

The BROWNING 767882 is a cast iron pillow block bearing designed to support rotating shaft assemblies in industrial and mechanical drive applications. It accepts a 1-11/16 inch inside diameter shaft and uses a set screw locking mechanism to secure the shaft in place. The bearing insert is made from 52100 steel, a high-carbon chromium alloy chosen for its hardness and fatigue resistance. Static load capacity is 5,139 pounds and dynamic load capacity is 7,901 pounds. Overall dimensions are 7-3/8 inches in length and 4-1/4 inches in height. Maintenance technicians, millwrights, and mechanical contractors typically install this type of bearing as part of conveyor systems, fan assemblies, pump drives, and general industrial machinery.

This pillow block is suited for light to medium industrial applications where a standard two-bolt mounting configuration is required. The 5-21/32 inch center-to-center mounting hole spacing and 2-1/8 inch base-to-center height make it compatible with standard mounting plate layouts. It is commonly found in HVAC fan shaft support, agricultural equipment, material handling systems, and general-purpose mechanical drive trains. The cast iron housing provides adequate rigidity for most stationary mounting environments.

Key Features

• 52100 steel bearing insert for high hardness and fatigue resistance
• 5,139 pound static load capacity and 7,901 pound dynamic load capacity
• Cast iron housing for rigid, stable mounting in stationary applications
• 5-21/32 inch between mounting hole centers for standard two-bolt installation
• 2-1/8 inch base-to-center height for consistent shaft alignment

Compatibility

Designed as an OEM-style replacement or direct-install pillow block bearing for industrial shaft support applications requiring a 1-11/16 inch bore and two-bolt cast iron housing.

Installation Notes

Installation is typically performed by millwrights or qualified mechanical technicians. Shut down and lock out all power to the drive system before removing or installing any bearing components. Ensure the mounting surface is flat and clean before torquing fasteners, and verify shaft alignment after securing the housing to avoid premature bearing wear. Do not overtighten set screws beyond the bearing manufacturer recommendations to prevent shaft damage.
