Browning 730063 Pillow Block Bearing 3.5 in Bore Cast Iron

Product Description

The BROWNING 730063 is a Type E nonexpansion pillow block bearing designed to support rotating shafts in industrial and commercial machinery applications. This unit features a 3.5-inch bore diameter and a cast iron housing, providing rigid, durable shaft support under heavy radial loads. The overall length is 14 inches with a base-to-center height of 3.75 inches and an outside diameter of 7.5 inches. Licensed millwrights, maintenance technicians, and industrial mechanics install this bearing in belt-driven equipment, conveyors, fans, and similar power transmission systems where fixed-end bearing support is required.

This pillow block is suited for fixed-end shaft mounting in industrial drive systems where nonexpansion bearing positioning is needed. The cast iron housing provides thermal stability and structural rigidity in moderate-duty environments. Mounting hole spacing ranges from 9.75 inches minimum to 11.5 inches maximum, allowing compatibility with standard pillow block base bolt patterns. The PBE920FX designation identifies this unit within the Browning bearing line for replacement and cross-reference purposes.

Key Features

• Type E nonexpansion design for fixed-end shaft positioning in two-bearing drive arrangements
• 3.5-inch maximum bore diameter accommodates standard industrial shaft sizes
• Cast iron housing delivers rigidity and resistance to deflection under radial load
• Adjustable mounting hole spacing from 9.75 inches to 11.5 inches fits multiple base configurations
• 3.75-inch base-to-center height for standard shaft centerline elevation above mounting surface
• 7.5-inch housing height and outside diameter provide substantial bearing support geometry

Compatibility

Designed as an OEM-style replacement or direct application pillow block bearing for industrial power transmission equipment requiring a Type E nonexpansion unit with a 3.5-inch bore and cast iron housing.

Installation Notes

Installation should be performed by a qualified millwright or industrial maintenance technician. De-energize and lock out all power to the drive system before removing or installing bearing units. Ensure the mounting surface is flat and clean before torquing mounting fasteners, and verify shaft alignment with the paired bearing before final tightening. Do not press or hammer directly on the bearing housing during shaft installation.
