FAQ

What are configurable mechanical components?

Configurable components are products in which you can select specific design features, and see the price and delivery times at a glance.

The most used configurators include linear shafts, linear guides, miniature linear guides, aluminum extrusions and aluminum sheets. Select your specifications from material, surface treatment, length and diameter.

Tailor-made processing

Our “DHM projects” tool allows you to save different projects or lists of articles on our website and sort them when it suits you. You can easily add them to your cart by clicking the "Add Project to Cart" button, or you can quickly edit them by removing and adding products from any device by logging into your account.
