Manufacturing Process

We produce nearly all cardan shaft components in-house with state-of-the-art CNC machines, enabling quick custom designs.


Raw Materials

Quality starts with top materials

We source forged and cast parts from Germany or Europe, prioritizing excellence.


Machinery

Our modern equipment handles all production in-house.

1. Machine Production

Nearly all components are crafted at our Gersfeld facility by skilled experts

Highlights include:


  • Splined hub sleeves with polyamide 11 (Rilsan) coating
  • Cold-rolled or hobbed shaft splines, boosting strength by 15-20% and reducing roughness for smooth, long-lasting performance
  • Precision spiders built with proven technology for accuracy

2. Assembly

Certified assembly tailored to your needs

We use submerged arc welding (DIN ISO 3834, EN 15085) under expert supervision, with regular tests for rail use. Balancing is customized up to 4800 mm, with certificates available. Painting offers all RAL colors with adjustable thickness, and shipping uses ISPM 15 crates.
