Browning 730018 Type E Nonexpansion Pillow Block 3.5in Id

Product Description

The BROWNING 730018 is a Type E nonexpansion pillow block bearing designed to support rotating shafts in fixed-position applications where axial movement is not required. With a 3.5-inch bore diameter and a cast iron housing, this unit provides rigid, durable shaft support in demanding industrial and mechanical drive systems. The 14-inch overall length and 7.5-inch height give it a substantial footprint suited for heavy-load installations. A base-to-center height of 3.75 inches positions the shaft centerline for alignment with matched drive components. Licensed millwrights, maintenance mechanics, and industrial equipment technicians are the primary installers of this bearing unit.

This pillow block is used in industrial conveyor systems, fan and blower drives, pump assemblies, and general power transmission equipment where a fixed bearing position is required. The nonexpansion design means this bearing serves as the locating bearing in a two-bearing shaft arrangement, holding the shaft against axial movement. It is typically paired with an expansion-type unit on the opposite shaft end to allow thermal growth. Applications span both light industrial and heavier process equipment installations.

Key Features

• Type E nonexpansion design serves as the fixed locating bearing in paired-bearing shaft setups
• 3.5-inch maximum bore diameter accommodates large-diameter industrial shafts
• Cast iron housing delivers strength and rigidity under heavy radial loads
• 3.75-inch base-to-center height provides consistent shaft centerline elevation for drive alignment
• Mounting hole spread between 9.75 and 11.5 inches suits standard industrial base plates and frames
• 7.5-inch outside diameter and 5-inch width support broad load distribution across the housing

Compatibility

Designed as an OEM-style fixed pillow block bearing replacement for industrial power transmission shaft assemblies requiring a 3.5-inch bore Type E nonexpansion unit.

Installation Notes

Installation should be performed by a qualified millwright or maintenance mechanic. Lock out and tag out all energy sources before removing or installing pillow block bearings on any rotating shaft. Confirm shaft and housing bore dimensions and check alignment with a straight edge or laser alignment tool before final torque on mounting fasteners. Do not drive the bearing onto the shaft using impact methods that transmit force through the rolling elements.
