Browning 730004 Type E Pillow Block 1.5 in Id Cast Iron

Product Description

The BROWNING 730004 is a Type E nonexpansion pillow block bearing unit designed to support rotating shafts in fixed-position mounting applications. Built from cast iron, it provides a rigid, durable housing that holds the bearing assembly at a consistent centerline height of 2.125 inches above the mounting base. With a 1.5-inch inside diameter bore, this unit accepts shafts up to 1.5 inches and is installed by millwrights, maintenance mechanics, and industrial technicians in conveyor, pump, fan, and general power-transmission applications. The overall length of 7.875 inches and two-bolt mounting base make alignment and installation straightforward on standard equipment frames.

This pillow block is suited for use in light-to-medium duty industrial and commercial machinery where a stationary (nonexpansion) bearing mount is required. Typical applications include conveyor drive shafts, blower assemblies, agricultural equipment, and HVAC fan shaft supports. The nonexpansion design means the bearing is fixed axially, making it the anchor point in shaft assemblies that pair it with a companion expansion unit at the opposite end to manage thermal growth.

Key Features

• Type E nonexpansion design fixes the shaft axially for use as the anchor bearing in two-bearing shaft assemblies
• Cast iron housing delivers rigid support and resistance to deflection under radial load
• 1.5-inch bore ID accommodates standard 1.5-inch shafts
• 2.125-inch base-to-center height provides consistent shaft positioning above the mounting surface
• Two-bolt mounting base with adjustable hole spacing between 5.6875 and 6.5 inches for flexible frame alignment
• 7.875-inch overall length suits standard industrial mounting footprints

Compatibility

Designed as an OEM-style replacement or new-installation pillow block for industrial shaft assemblies requiring a Type E nonexpansion unit with a 1.5-inch bore and cast iron housing.

Installation Notes

Installation should be performed by a qualified millwright or maintenance mechanic. De-energize and lock out all connected drive equipment before mounting or removing bearing units per applicable OSHA lockout-tagout procedures. Align the shaft carefully through both bearing housings before final bolt torque to avoid preloading the bearing races. Ensure the mating expansion-type bearing is used at the opposite shaft end to allow for thermal shaft growth.
