Gibraltar BHG3727-G Steel Shoulder Bushing 1.0005 in Id

Product Description

The GIBRALTAR BHG3727-G is a steel die mold shoulder bushing designed for precision friction-fit applications in tooling and mold assemblies. It features a 1.0005-inch inside diameter and an overall length of 4.875 inches, with a bottom outside diameter of 1.3755 inches and a top outside diameter of 1.552 inches. The stepped shoulder design and press-fit attachment method allow for secure, repeatable positioning within mold bases and die sets. Installation requires no lubrication, as this is a non-self-lubricating friction bushing. Machinists, toolmakers, and industrial maintenance technicians are the typical installers of this component.

This shoulder bushing is used in die mold tooling applications where precise bore alignment and a secure press-fit are required. The stepped outside diameter profile seats positively within a counterbored mold plate, keeping the bushing retained under load. It is suited for both production tooling and repair situations where an OEM-style steel friction bushing is needed. The 1.0005-inch ID accommodates standard leader pin or guide pin stock at that nominal diameter.

Key Features

• 1.0005-inch inside diameter for precise leader pin or guide pin fit
• Stepped shoulder profile with 1.3755-inch bottom OD and 1.552-inch top OD
• Press-fit attachment method for secure, non-rotating retention in mold plates
• Non-self-lubricating friction bushing — requires external lubrication as part of maintenance routine
• Steel construction for durability in high-cycle die and mold environments
• 4.875-inch overall length suits deep mold plate configurations

Compatibility

Designed as an OEM-style replacement or new-installation shoulder bushing for die mold tooling assemblies requiring a press-fit steel friction bushing with a 1.0005-inch inside diameter.

Installation Notes

Installation is typically performed by toolmakers or industrial maintenance personnel using a hydraulic or arbor press to achieve proper press-fit seating without damaging the bore. Always clean and deburr the mating bore in the mold plate before pressing the bushing into position. Do not drive the bushing with a hammer directly against the head face, as this can distort the shoulder. Follow the tooling manufacturer's specifications for interference fit tolerances and lubrication intervals after installation.
