Gibraltar STB-4509 Die Mold Straight Bushing Steel

Product Description

The GIBRALTAR STB-4509 is a straight-style die mold bushing machined from steel, designed to guide punches, pins, or components with precision in die sets and mold tooling. With an inside diameter of 1.5005 inches and a body diameter of 2.0005 inches, this bushing provides a controlled fit for repeatable alignment in press tooling applications. Installation is accomplished via press-fit, securing the bushing firmly in the die plate without additional fasteners. The non-self-lubricating design requires periodic manual lubrication during service, making it appropriate for applications where lubrication can be managed at scheduled intervals.

The STB-4509 is used in stamping dies, mold bases, and precision tooling fixtures found in industrial manufacturing environments. Straight bushings of this type are installed by tool and die makers and precision machinists during die assembly or maintenance. The straight body geometry suits through-hole press-fit installations in die plates and mold bases where consistent bore alignment and concentricity are critical to component quality and die performance.

Key Features

• Inside diameter of 1.5005 inches for precise guided-fit applications
• Body diameter of 2.0005 inches for press-fit installation in standard die plate bores
• Steel construction provides durability under repeated press-load cycling
• Non-self-lubricating design suitable for manually lubricated tooling programs
• Straight bushing style for through-hole installations in die sets and mold bases
• Sold individually, minimum order quantity of 1

Compatibility

Designed as an OEM-style replacement or direct-install straight bushing for die sets and mold bases requiring a 1.5005 inch inside diameter press-fit steel bushing.

Installation Notes

Installation of this press-fit bushing requires an arbor press or hydraulic press to seat the bushing flush and square in the die plate bore. Ensure the receiving bore is clean, free of burrs, and dimensioned to the appropriate interference fit before pressing. De-energize and lock out all associated press equipment before performing die work. Apply manual lubrication to the bore surface per the tooling maintenance schedule, as the bushing does not contain self-lubricating material.
