Product Description
Introduction
Shoulder Guide Bushing is a precision mold component designed to ensure accurate alignment between guide pillars and mold plates in stamping dies and injection molds. It plays a critical role in maintaining smooth movement during mold operation, reducing friction, and improving overall tooling stability. With a stepped shoulder structure, it provides strong positioning support and helps extend the service life of both the mold and guiding system.
Manufactured from high-quality bearing steel or alloy steel, the guide bushing is heat treated and precision ground to achieve high hardness, excellent wear resistance, and stable dimensional accuracy. Its inner bore is finely finished to ensure smooth sliding with the guide pillar, even under high-speed and high-load working conditions. Standard sizes are widely used in industrial tooling, while custom specifications can be produced according to drawings or application requirements.
This product is commonly used in stamping dies, progressive dies, plastic injection molds, and die-casting tools. It is also suitable for precision machinery and automated production systems that require reliable guiding performance. Available in MISUMI, HASCO, DME, and other international standards, Shoulder Guide Bushings are an essential solution for improving mold accuracy, reducing maintenance, and ensuring consistent production quality.
