Roller Guide Post Sets, also known by various names such as Guide Unit with collar, MILLIONGUIDE, and needle roller guide posts in different countries and regions, play a crucial role in mold manufacturing. They ensure high precision and low friction during operation.
Due to their unique structure, these guide posts can achieve zero contact among rollers, significantly reducing friction and enhancing performance.
Circular Ball Type vs Roller Type
In the current market, guide posts for stamping dies predominantly use the Circular Ball Type. However, with the rapid development of electric vehicles, the demand for higher precision and lower friction in die stamping processes has increased. This has led to the widespread adoption of Roller Type guide posts.
Characteristics of Circular Ball Type
Traditional Circular Ball Type guide posts have the following characteristics:
- Contact and Collision: Balls contact and collide with each other, generating friction, which leads to wear, dust generation, and heat.
- Cyclic Preloading: During operation, the balls undergo repeated preloading and unloading, causing vibrations.
Advantages of Roller Type
In contrast, Roller Type guide posts offer significant advantages:
- Zero Contact Design: Rollers do not contact each other, eliminating friction, wear, and dust generation.
- Low Preload and Smooth Rolling: The non-cyclic design with low preload results in minimal impact and vibration, enabling smoother rolling.
- Durable Structure: Comprising Needle Roller Cage (plastic), Guide Bush (hardened steel), Guide Unit (hardened steel), and Needle Roller (hardened steel), the structure is robust and durable.
