Why are we your partners for both today and tomorrow?

Because we have always aspired to absolute precision – irrespective whether it's large or small-scale production. And we invest in this. Continuously.

Home|About us

Your success is what drives us.

For more than 70 years, Stelter Zahnradfabrik GmbH has been a byword for gears and drive elements of outstanding quality. With its headquarters in Bassum near Bremen, Germany, the family company today produces high-tech gears in large and small-scale series for reputable manufacturers from the automotive, industrial, wind power and railway industries. Over 400 dedicated employees using highly automated production processes on production premises spanning approx. 29,000 m² ensure the manufacture of high-precision gears of great diversity – and with maximum efficiency.

The right partner for certain – and in the future, too.

Long-standing customers know that Stelter stands for absolute delivery reliability and quality. Even though we produce millions of geared drive elements year after year, it is only seldom that we reach the limits of our capacity. This is down to our approach, whereby we look ahead to plan our capacities and pursue an intelligent innovation strategy. As a result, we are always able to help our customers, even with bottlenecks that are unexpected or arrive at short notice.

Top delivery performance and quality leadership are no accident. We invest continuously in state-of-the-art machinery, automation systems and quality management, as well as in the further training of our employees. The takeover of entire gear manufacturing operations and machine plants is also one of our strengths.

Stelter grows in tandem with its customers. Not just in terms of batch sizes or gear geometries – we are now producing unit weights of up to module 44 and 2 tons. New drive technologies are placing ever changing requirements on the products of our customers, and thus also on our production techniques. We face these challenges with the constant further development and modernisation of our machinery.

We at Stelter see ourselves as a traditional medium-sized company: short lines of communication, flat hierarchies and a friendly atmosphere are what characterises us. This close cooperation ensures, for example, that investment decisions can be made non-circuitously and in the shortest-possible time. This means we can always act flexibly and respond to the changes and requirements of the market and our customers. A great culture of trust within our family-owned, medium-sized company and the long-term close relationship with our customers makes us what we are today and spurs our constant further development.

Our biggest asset is our employees. We endeavour to encourage every single individual according to their personal abilities. This is how we strengthen not only individual characters, but also teams, departments and ultimately the company as a whole. Accordingly, we oppose any forms of discrimination, stigmatisation or segregation. At Stelter, every person enjoys an equal, inviolable dignity and the same inalienable human rights, irrespective of their origin, skin colour, culture, religion, gender or sexual orientation. The company sets out binding standards for all employees in its “Code of Conduct”.
