Browning 730003 Type E Pillow Block Bearing 1-7/16 in Id

Product Description

The BROWNING 730003 is a Type E nonexpansion pillow block bearing designed to support rotating shafts in fixed-position applications. The unit accepts a 1-7/16 inch bore diameter and features a cast iron housing that provides rigid support under moderate to heavy radial loads. With a base-to-center height of 1-7/8 inches and an outside diameter of 3-3/4 inches, this bearing fits standard mounting layouts common in conveyor, fan, pump, and general power-transmission equipment. Installation requires standard bolted mounting and shaft-to-bore alignment. Licensed mechanics and millwrights typically handle these installations in industrial and commercial settings.

This pillow block is suited for fixed-shaft applications where axial float is not required. The nonexpansion design locks the shaft in position along its axis, making it appropriate for the driven end of a shaft assembly when used alongside an expansion-style unit on the opposite end. Typical applications include light industrial machinery, agricultural equipment drives, conveyor head and tail shafts, and fan shaft assemblies requiring reliable fixed-point bearing support.

Key Features

• Type E nonexpansion design locks shaft axially for fixed-end mounting
• 1-7/16 inch bore diameter accommodates standard shaft sizing
• Cast iron housing provides rigid support under radial and moderate shock loads
• 1-7/8 inch base-to-center height suits standard equipment mounting profiles
• Mounting hole spread of 5.00 inches minimum to 6.00 inches maximum for flexible base alignment
• 3-3/4 inch outside diameter with 3 inch width for compact shaft support

Compatibility

Designed as an OEM-style replacement or direct-fit pillow block bearing for fixed-shaft power transmission applications requiring a 1-7/16 inch bore Type E nonexpansion housing in a cast iron pillow block configuration.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. De-energize and lock out all power to the equipment before removing or installing any bearing housing. Ensure the shaft and bore are clean and free of burrs before pressing or sliding the shaft into the bore. Torque mounting fasteners evenly to seat the housing flat against the base plate, and verify shaft alignment before returning the equipment to service.
