Guide pillars

Guide pillars play a crucial role in press tools by ensuring precise positioning and form the basis for guiding moving components. They contribute to maintaining stability, precision, and durability of the entire tool. Various types of guide pillars are available to meet specific application requirements.

Pillars for plain or linear ball guides

Our guide pillars can be used in traditional guiding systems with steel or bronze bushes, as well as in ball guidance systems depending on requirements.

Plain linear guide system

Plain guidance of a press tool involves the use of bearing surfaces without rolling elements, ensuring smooth and even movement. In this context, the guide pillar guarantees stability and precision in tool movement, minimizing friction and ensuring optimal alignment for efficient and precise pressing operations.

Plain guide system

Ball guidance of a press tool uses balls to reduce friction and facilitate linear movement of the tool, ensuring high precision and fluidity in faster operating conditions.
The guide pillar, when mounted with a ball cage and bush, forms the basis of this arrangement, allowing stable and precise movement of the die set, which is crucial for high-frequency stamping tools.

Grinding and superfinishing

Superfinishing through grinding enhances the guide pillars' precision by creating ultra-smooth and perfectly aligned surfaces. The roughness is optimal with Ra = 0.2. This reduces friction, increases durability, and optimizes linear movement, essential for precise and fluid industrial operations.

Guide pillars guarantee your tool's perpendicularity

Grinding the pillar's working part and the surface under its collar (easyfit system) ensures precise perpendicularity, guaranteeing optimal alignment between components. This reduces wear, improves stability, and enhances the quality of pressing operations by ensuring smooth and precise movements.

Column hardness

The hardening process, resulting in a hardness of 64 HRC for the pillars, ensures exceptional wear resistance due to the reinforced crystalline structure. This essential property extends the pillars lifespan, making them ideal for demanding stamping applications and prolonging their operational life.
