About Stieber

Stieber was founded in 1937 in Munich and is now a medium-sized company employing 140 staff in Heidelberg and the Garching area near Munich.

The core business activities of Stieber are the design and production of drive elements for mechanical engineering systems. Our main strength lies in the development and production of overrunning clutches and backstops, which transmit torque via friction.

Stieber reflects numerous innovative developments throughout the company's history of innovation, making it a leader in the European market. For example, Stieber has once again demonstrated its technical competence in developing and designing the world's largest backstop. This backstop and other backstops can be successfully used even under the most severe conditions.

Stieber is part of the Altra Industrial Motion Group and, together with its sister companies Formsprag and Marland in the United States, is a global market leader in overrunning clutches and backstops.

Stieber's global service network, including more than 1000 stockist distributors and technical centers, ensures that we remain close to our customers.

Customer satisfaction is the corporate philosophy of Stieber. To achieve this goal, our processes are continuously improved.

Since 1997, Stieber has been certified according to DIN EN ISO 9001, and since 2000 has been certified according to ISO 14001 (Environmental Management System). In addition, internal monitoring processes ensure that quality, timeliness, and costs remain leading priorities.
