Gibraltar BHG3714-G Steel Shoulder Bushing 0.8755in Id

Product Description

The GIBRALTAR BHG3714-G is a steel die mold shoulder bushing designed to guide and align components within die sets, molds, and precision tooling assemblies. With an inside diameter of 0.8755 inches and an overall length of 3.375 inches, this bushing provides a friction-fit bearing surface for guide pins and similar tooling elements. The press-fit attachment method seats the bushing securely into a bored hole without additional fasteners. This part is non-self-lubricating, so periodic lubrication is required during service. Machinists, toolmakers, and die maintenance technicians are the primary installers of this component.

This shoulder bushing is suited for use in progressive dies, injection molds, and stamping tooling where precise pin alignment is critical. The stepped shoulder design locates the bushing at a fixed depth within the die plate, eliminating axial migration under cyclic load. The bottom outside diameter of 1.2505 inches is the press-fit body, while the top outside diameter and head diameter of 1.4375 inches seat flush against the mating plate surface. It is appropriate for both production tooling and MRO replacement applications in metal fabrication and plastics processing environments.

Key Features

• Press-fit body seats securely in bored die plate without additional fasteners
• Stepped shoulder head controls axial position and provides a positive stop
• Non-self-lubricating friction bushing — compatible with oil or grease lubrication schedules
• Steel construction for durability under cyclic load in die and mold applications
• Precision decimal bore of 0.8755 inches for accurate pin guidance

Compatibility

Designed as an OEM-style replacement or new-installation bushing for standard die sets and mold bases requiring a press-fit shoulder bushing with a 0.8755 inch inside diameter and 3.375 inch overall length.

Installation Notes

Installation is typically performed by a qualified toolmaker or die maintenance technician. The receiving bore should be machined to the appropriate interference fit tolerance before pressing the bushing into place; use an arbor press and a proper driver to avoid cocking or damaging the bushing during installation. Remove the die set from service and ensure all hydraulic or mechanical press energy is isolated before servicing bushings. Because this bushing is non-self-lubricating, establish a lubrication interval appropriate to the application cycle rate before returning the tooling to production.
