Browning 730052 Pillow Block Bearing 3 Inch Type E

Product Description

The BROWNING 730052 is a Type E nonexpansion pillow block bearing designed for industrial shaft support applications. It features a 3 inch bore (inside diameter) and accepts shafts up to 3 inches in maximum bore diameter. The overall length is 12 inches, and the base-to-center height is 3.125 inches. The housing is cast iron, providing strength and rigidity in demanding environments. This unit is a fixed (nonexpansion) style, meaning it controls axial shaft positioning and is typically used as the locating bearing in a two-bearing shaft arrangement. Licensed millwrights, industrial mechanics, and maintenance technicians are the primary installers.

This pillow block is suited for general industrial and mechanical drive applications where a heavy-duty cast iron housing is required. Common install scenarios include conveyor drives, fan shafts, pump assemblies, and other rotating equipment found in manufacturing, agricultural, and HVAC mechanical room environments. The mounting hole spread ranges from approximately 8.44 inches (minimum) to 9.75 inches (maximum), allowing for flexible base plate fitment. The 4.5 inch housing width and 6.25 inch outside diameter provide a stable, broad footprint for high-load shaft support.

Key Features

• Type E nonexpansion design controls axial shaft position in fixed-bearing arrangements
• 3 inch bore ID with maximum bore capacity of 3 inches for precision shaft fit
• Cast iron housing delivers rigidity and durability in heavy industrial service
• Base-to-center height of 3.125 inches for predictable shaft centerline alignment
• Adjustable mounting spread from 8.44 to 9.75 inches accommodates varied base plates
• 26 pound unit weight reflects robust, heavy-duty construction

Compatibility

Designed as an OEM-style replacement or new-installation pillow block for industrial shaft assemblies requiring a Type E nonexpansion cast iron housing with a 3 inch bore and 12 inch overall length.

Installation Notes

Installation should be performed by a qualified millwright or industrial mechanic. De-energize and lock out all drive equipment before removing or installing bearing units, following LOTO procedures per applicable safety standards. Ensure the mounting surface is clean, flat, and level before torquing fasteners to prevent housing distortion. In a two-bearing shaft arrangement, the nonexpansion (fixed) bearing should be positioned to control axial float while the expansion bearing allows thermal shaft growth.
