Browning 730053 Type E Pillow Block Bearing 3-7/16 in Id

Product Description

The BROWNING 730053 is a Type E nonexpansion pillow block bearing designed to support rotating shafts in fixed-position bearing applications. Built from cast iron, this unit accepts a 3-7/16 inch bore and stands 7-1/2 inches from base to top of housing, with a base-to-center height of 3-3/4 inches. At 44 pounds, it is a heavy-duty unit suited for industrial conveyor systems, fan shafts, mixer drives, and similar power transmission equipment. Licensed millwrights, maintenance mechanics, and industrial equipment technicians are the typical installers. The nonexpansion design fixes the shaft axially at the bearing location, making placement relative to the expansion bearing on the same shaft critical during installation.

This pillow block is used in industrial and commercial power transmission assemblies where a fixed bearing point is required on a shaft. Common applications include bulk material handling conveyors, industrial fans, aggregate processing equipment, and pump drive systems. The cast iron housing provides durability in moderate-duty environments where vibration and radial load demands are significant. The manufacturer part number for this unit is also referenced as PBE920FX, which may appear on legacy equipment drawings or maintenance records.

Key Features

• Type E nonexpansion design fixes the shaft axially at the bearing seat
• 3-7/16 inch maximum bore diameter accommodates common industrial shaft sizes
• Cast iron housing provides strength and vibration damping in demanding drive applications
• Mounting hole spacing ranges from 9.75 inches minimum to 11.50 inches maximum for flexible base plate fitment
• 5 inch housing width and 7-1/2 inch overall height suit standard pillow block mounting pads
• 44 pound unit weight reflects heavy-duty cast iron construction for high-load service

Compatibility

Designed as an OEM-style replacement or new-installation Type E nonexpansion pillow block bearing for industrial power transmission shafts with a 3-7/16 inch diameter. This unit is also identified by the model designation PBE920FX as noted in the product data.

Installation Notes

Installation should be performed by a qualified millwright or maintenance mechanic familiar with shaft alignment and bearing seating procedures. Power down and lock out the drive system completely before removing the old bearing or positioning the new unit. When used alongside an expansion bearing on the same shaft, the nonexpansion unit should be positioned first to establish the fixed axial reference point. Verify that the mounting surface is level and that fastener torque follows the equipment manufacturer or facility maintenance specifications.
