Gibraltar STB-4510 Die Mold Straight Bushing Steel

Product Description

The GIBRALTAR STB-4510 is a straight-style die mold bushing machined from steel and designed for precision guide and locating applications in mold and die assemblies. It features a 2.005 inch inside diameter and a 2.5005 inch body diameter, allowing for accurate press-fit installation into mold plates and tooling blocks. The non-self-lubricating construction means external lubrication is applied as needed based on cycle demands. This bushing is a standard component handled by toolmakers, mold builders, and die maintenance technicians working with injection molds, stamping dies, and similar precision tooling setups.

The STB-4510 fits into applications where a straight-bore press-fit bushing is required to guide leader pins, ejector pins, or similar tooling components. It is suited for use in both new mold construction and maintenance replacement scenarios. With a body length of approximately 3.88 inches and a compact outside profile, it integrates into standard die set plates without modification when the bore is sized to accept a 2.5005 inch press-fit diameter. Toolmakers working in production shops or tool rooms will recognize this as a direct-fit replacement or new-build component for standard die mold guide systems.

Key Features

• Steel construction provides durability and dimensional stability under repeated tooling loads
• 2.005 inch inside diameter for precise pin and guide clearance in mold assemblies
• 2.5005 inch body diameter engineered for reliable press-fit retention in tooling plates
• Straight bushing style suits standard die set and mold base guide applications
• Non-self-lubricating design allows technicians to select and apply lubrication appropriate to the application
• Single-piece packaging with a minimum order quantity of 1 for convenient replacement purchasing

Compatibility

Designed as an OEM-style replacement or new-build component for standard straight-bore die mold guide bushing applications requiring a 2.005 inch inside diameter and a 2.5005 inch press-fit body diameter.

Installation Notes

Installation is typically performed by a toolmaker or die maintenance technician using a hydraulic or arbor press to seat the bushing flush or to the required depth in the mold plate bore. The tooling assembly should be fully de-energized, de-pressurized, and cooled before any bushing replacement or installation work begins. Verify bore diameter and surface finish before pressing to avoid galling or improper fit. Apply lubrication per shop specifications after installation since this part does not contain integral lubricant.
