Gibraltar STBGP-5509 Die Mold Straight Bushing Steel

Product Description

The GIBRALTAR STBGP-5509 is a straight-style die mold bushing machined from steel, designed to guide punches, pins, and tooling components within die sets and mold bases. The bushing features a 2.5005-inch inside diameter and a 3.2505-inch body diameter, with a press-fit attachment method that locks it securely into the die plate without fasteners. Its self-lubricating construction reduces the need for external grease or oil during normal operation, making it well-suited for production tooling environments where maintenance access is limited. Toolmakers, die setters, and mold technicians install this type of component during die assembly or scheduled tooling rebuilds.

This bushing is applied in precision die and mold assemblies where accurate punch or pin guidance is critical to part quality and tool life. It fits into die sets used in stamping, forming, and injection mold operations across industrial and manufacturing settings. The press-fit design is standard in both prototype and high-volume production tooling. Installation is typically performed by toolmakers or skilled machinists working to close dimensional tolerances on the die plate bore.

Key Features

• 2.5005-inch inside diameter for precise punch and pin guidance
• 3.2505-inch body diameter sized for standard die plate press-fit bores
• Press-fit attachment method eliminates the need for set screws or retaining rings
• Self-lubricating construction reduces routine lubrication maintenance
• Steel construction provides durability under repetitive load and impact
• Straight bushing style compatible with standard die set configurations

Compatibility

Designed as an OEM-style replacement or new-installation component for straight-style die mold bushing applications requiring a 2.5005-inch inside diameter and press-fit mounting in steel die plates.

Installation Notes

Installation is performed by qualified toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush and square within the die plate bore. Verify bore diameter and surface finish before pressing to avoid galling or misalignment. Do not hammer the bushing directly without a driver plate, as this can damage the bore or distort the bushing. Dimensional inspection of the installed bushing ID is recommended before the die set is returned to service.
