Gibraltar BHG3746-G Steel Shoulder Bushing 1-1/2 in Id

Product Description

The GIBRALTAR BHG3746-G is a steel die mold shoulder bushing designed for precision fit and load-bearing alignment in mold and die tooling applications. With a 1-1/2 inch inside diameter and an overall length of 4-3/8 inches, this bushing provides a stable guiding interface between mold components. The head diameter measures 2-3/16 inches with a head height of 3/16 inches, allowing it to seat flush against mold plates. It is a friction-type, non-self-lubricating bushing, meaning it requires an appropriate external lubricant during service. Toolmakers, die setters, and mold maintenance technicians are the primary installers of this component.

This shoulder bushing is used in die mold assemblies where precise component alignment is critical to part quality and tool longevity. It is suited for both production tooling and maintenance replacement scenarios in manufacturing environments. The bushing is typically pressed or fitted into a mold plate to guide leader pins or similar components through repeated press cycles. Applications span injection molds, stamping dies, and similar precision tooling setups where a steel friction bushing is the specified standard.

Key Features

• 1-1/2 inch inside diameter for precise leader pin or guide pin fitment
• 4-3/8 inch overall length provides extended guiding surface for alignment stability
• 2-3/16 inch head diameter with 3/16 inch head height for positive plate seating
• Steel construction offers durability under high-cycle press and mold conditions
• Non-self-lubricating friction type requires periodic external lubrication during service
• Sold individually — one bushing per package

Compatibility

Designed as an OEM-style replacement or direct-fit component for die mold assemblies requiring a steel shoulder bushing with a 1-1/2 inch inside diameter and 4-3/8 inch overall length.

Installation Notes

Installation is typically performed by a toolmaker or qualified die maintenance technician. Before servicing or replacing a shoulder bushing, ensure the press or molding machine is fully de-energized, locked out, and at zero pressure per applicable OSHA lockout/tagout procedures. The bushing should be pressed into the mold plate bore using appropriate tooling to avoid cocking or damage to the bore surface. Because this is a non-self-lubricating bushing, apply a compatible grease or lubricant to the ID surface at installation and maintain a regular lubrication schedule thereafter.
