Browning 730050 Type E Pillow Block 2-7/16 in Id Cast Iron

Product Description

The BROWNING 730050 is a Type E nonexpansion pillow block bearing unit designed for fixed-position shaft support in industrial and mechanical drive applications. Constructed from cast iron, this unit accepts a 2-7/16 inch bore diameter and stands 5-1/2 inches from base to top. The base-to-center height is 2-3/4 inches, and the overall assembly measures 10-1/2 inches in overall length. The nonexpansion design holds the shaft axially in place, making it the fixed anchor point in a two-bearing shaft arrangement. Licensed HVAC, mechanical, or millwright technicians handling power transmission equipment will find this unit sized for medium-duty shaft loads in conveyor, blower, and fan drive systems. The unit weighs 19 pounds.

This pillow block is suited for industrial rotating equipment where a fixed bearing position is required along a horizontal shaft. Typical applications include commercial and industrial fan assemblies, conveyor drive shafts, and blower units where one end of the shaft must be anchored against axial movement. The 2-7/16 inch bore accommodates standard shaft sizes common in HVAC fan arrays, industrial blowers, and material handling equipment. The cast iron housing provides rigidity under steady radial and moderate thrust loads in these environments.

Key Features

• Type E nonexpansion design anchors shaft axially at the fixed bearing position
• 2-7/16 inch maximum bore diameter accommodates standard mid-range industrial shaft sizes
• Cast iron housing provides structural rigidity under radial and moderate thrust loads
• 5-1/2 inch outside diameter and 4 inch width deliver a stable, low-profile mounting footprint
• Mounting hole spread ranges from 7.125 inches minimum to 8.75 inches maximum for flexible base mounting
• Single-unit packaging with a minimum order quantity of one for direct replacement purchases

Compatibility

Designed as an OEM-style replacement or direct-fit pillow block for industrial shaft assemblies requiring a Type E nonexpansion bearing unit with a 2-7/16 inch bore and cast iron housing.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. De-energize and lock out all drive equipment before removing or installing bearing units, following LOTO procedures per applicable OSHA and ANSI standards. Ensure the mounting surface is flat and clean before torquing the hold-down fasteners, and align the shaft carefully between the fixed and expansion bearing positions before final tightening. Do not force the bore onto the shaft with impact tools, as this can damage the bearing insert.
