Browning 730017 Type E Nonexpansion Pillow Block 3-7/16 in Id

Product Description

The BROWNING 730017 is a Type E nonexpansion pillow block bearing unit designed to support rotating shafts in fixed-position mounting applications. With a 3-7/16 inch bore ID and cast iron housing, this unit is built for demanding industrial and mechanical drive systems where rigidity and load capacity are required. The base-to-center height measures 3-3/4 inches, and the overall height of the housing is 7-1/2 inches. At 44 pounds, it is a heavy-duty unit suited for industrial machinery, conveyor systems, and power transmission equipment. Licensed millwrights, industrial mechanics, and maintenance technicians handle installation in most settings.

This pillow block is used in fixed-shaft power transmission assemblies where the bearing must remain stationary along the shaft axis. Typical applications include conveyor drives, fan shafts, and process equipment in manufacturing, aggregate, and material handling environments. The nonexpansion design means this unit holds the shaft axially and is paired with an expansion-type unit at the opposite end of the shaft to allow for thermal growth. The 3-7/16 inch maximum bore diameter accommodates standard shaft sizing in medium-to-heavy industrial drive systems.

Key Features

• Type E nonexpansion design controls axial shaft positioning in paired-bearing installations
• 3-7/16 inch bore ID fits standard medium-to-heavy industrial shaft diameters
• Cast iron housing provides rigidity and durability in high-load environments
• 3-3/4 inch base-to-center height suits standard mounting platforms
• Mounting hole spread adjustable between 9.75 inches minimum and 11.50 inches maximum for installation flexibility
• 44-pound unit weight reflects heavy-duty construction for demanding applications

Compatibility

Designed as an OEM-style replacement or new-installation pillow block for industrial power transmission systems requiring a Type E nonexpansion bearing unit with a 3-7/16 inch bore diameter.

Installation Notes

Installation should be performed by a qualified industrial mechanic or millwright familiar with shaft alignment and bearing mounting procedures. Power down and lock out all associated drive equipment before mounting or removing the bearing unit. Ensure the mounting surface is flat and clean before torquing hold-down fasteners, and always pair this nonexpansion unit with a matching expansion-type pillow block on the opposite shaft end to accommodate thermal growth. Follow applicable ANSI and machinery OEM specifications for bearing installation clearance and lubrication intervals.
