Gibraltar BHG3730-G Steel Shoulder Bushing 1.2505 in Id

Product Description

The GIBRALTAR BHG3730-G is a steel die mold shoulder bushing designed for use in die sets, molds, and precision tooling assemblies. This friction-type bushing features a press-fit attachment method and a stepped shoulder design that seats positively into a counterbored hole, providing accurate alignment of mating components. The inside diameter measures 1.2505 inches, the overall length is 1.375 inches, and the bushing is non-self-lubricating, requiring periodic lubrication in service. It is installed by toolmakers, die setters, and machine shop professionals working with stamping dies, injection molds, and similar precision fixtures.

This shoulder bushing is suited for industrial tooling applications where repeatable alignment and consistent press-fit retention are required. The stepped body, with a bottom outside diameter of 1.6255 inches and a top outside diameter of 1.8020 inches, allows the bushing to seat flush against a shoulder bore. Typical applications include die shoe assemblies, guide post systems, and fixture plates in production stamping and molding environments. It is sold and stocked individually.

Key Features

• Press-fit attachment method for secure, positive retention in counterbored holes
• Stepped shoulder design with 1.6255 inches bottom OD and 1.8020 inches top OD for accurate seating
• Inside diameter of 1.2505 inches for precise alignment of mating guide components
• Non-self-lubricating friction bushing requiring external lubrication during service
• Head diameter of 1.8125 inches with a head height of 0.1875 inches
• Steel construction for strength and wear resistance in industrial tooling use

Compatibility

Designed as an OEM-style replacement or direct installation bushing for standard die set and mold base assemblies requiring a press-fit shoulder bushing with a 1.2505-inch inside diameter.

Installation Notes

Installation is typically performed by a toolmaker or die technician using an arbor press to drive the bushing into a properly sized counterbore. The receiving bore must be dimensioned to achieve correct press-fit interference before installation. De-energize or lock out all machinery before servicing any die or mold assembly. Because this bushing is non-self-lubricating, apply an appropriate lubricant to the bore at regular service intervals to prevent premature wear.
