Made in Germany

Trapezoidal Lead Screws and Nuts

We manufacture your custom-made trapezoidal lead screws and nuts according to your drawing. Thanks to our innovative and high-quality manufacturing process, micro-pockets are formed on the flank surface, which is ideal for the adhesion of lubricants. As a result, our trapezoidal threaded spindles have a longer service life and reduced risk of the dreaded stick-slip effect.

Trapezoidal Screws at Work

A trapezoidal thread is a moving drive thread and has to endure a high friction rate. This usually means the threaded part of the screw is self-locking and therefore has the advantage that it does not have to be secured separately in a resting position. Trapezoidal screws are used in various ways, and can be used:

  • as feedscrews in laboratory and life sciences equipment
  • as lifting screws or power screws in heavy lifting applications often combined with a load and safety nut
  • as leadscrews for the transmission of motion and power in machine tools
  • for exerting heavy force: e.g. in mechanical presses
  • for conveying and squeezing materials: e.g. in screw conveyors, injection moulding machines or screw pumps
  • for linear motion applications, with slower rotational speeds and heavy load requirements
  • as leadscrews for bidirectional motion loads
  • as multi-start trapezoidal screw to transform smaller radial movements into large axial movements

Your Tailor Made Trapezoidal Screw

In addition to standard trapezoidal threads and matching trapezoidal thread nuts, we also manufacture special threads with measurements that deviate from standard sizes. These come ready to install with the corresponding nuts, and including all the necessary milling and turning operations, as well as quenching and surface treatments. If you need a trapezoidal screw with multi-start threads, this is also possible, with 2, 3, 4, 30 starts or any number of starts your application requires. This differentiates us from other leadscrew manufacturers – we focus on your individual needs.
