LTN stands for partnership


Technology begins with the people it supports. That’s our creed. Learn why here.


Ever since we were founded in 1979, our work and our successes have been based on listening to our customers and understanding their problems.

Only in this way can innovation flourish. From prototype through custom-made product to series manufactured, every component that leaves our premises is the outcome of a partnership.

Wherever something needs to be turned or transmitted, we can and would like to – indeed we should and must – be your partner. No matter what the industry or the application, no matter how high up or how deep down and regardless of the wind or weather.

We look forward to your ideas.

High quality standards at LTN Servotechnik


No matter whether there are five or 50,000 of them, all our components are manufactured according to the highest standards. In order for our customers to become our partners, we need to understand them and be capable of brainstorming together, thinking ahead and providing answers to burning questions. That’s why we maintain not only our systems but also a think tank – our Engineering department – which allows us to explore new avenues in technology, sustainability and profitability together with our customers through research, development and design.
