Gibraltar BHG3713-G Steel Shoulder Bushing 0.8755 Id

Product Description

The GIBRALTAR BHG3713-G is a steel die mold shoulder bushing designed for precision alignment and guiding applications in mold and die assemblies. With an inside diameter of 0.8755 inches, a bottom outside diameter of 1.2505 inches, a top outside diameter of 1.427 inches, and an overall length of 2.875 inches, this bushing provides accurate bore guidance under press-fit installation. The head diameter measures 1.4375 inches with a head height of 0.1875 inches. Constructed from steel, it is suited for high-load, repetitive-cycle tooling environments where dimensional consistency is critical. Installation is performed by tool and die makers or precision machining professionals.

This shoulder bushing is intended for use in die sets, molds, and fixture plates where a press-fit friction bushing is required for leader pin or guide post alignment. It is a non-self-lubricating, friction-type bushing, meaning periodic lubrication with an appropriate die lubricant is required depending on cycle rate and load. Typical applications include stamping dies, injection mold bases, and similar tooling assemblies used in manufacturing and fabrication environments.

Key Features

• Steel construction for durability in high-cycle die and mold applications
• Press-fit attachment method for secure, precise seating in the bore
• Inside diameter of 0.8755 inches for accurate guide pin clearance
• Shoulder design with 1.4375 inch head diameter and 0.1875 inch head height for positive axial positioning
• Non-self-lubricating friction type requires external lubrication as needed
• Single-piece unit sold individually (package quantity of 1)

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard die set and mold base assemblies requiring a press-fit steel shoulder bushing with a 0.8755 inch inside diameter.

Installation Notes

Installation is typically performed by tool and die makers using a hydraulic or arbor press to achieve proper press-fit seating without damaging the bore or bushing head. Ensure the receiving bore is clean, dimensionally correct, and free of burrs before pressing the bushing into place. Do not drive the bushing with impact tools, as this can cause misalignment or distortion. Apply appropriate die lubricant to the inside diameter during assembly and as required during service based on application demands.
