About us

KBK Antriebstechnik - successful since 2003

Ideal and combinable solutions – that is exactly what KBK has been successfully offering for 12 years in the product lines metal bellows-, servo insert- and safety-couplings as well as torque limiters, line shafts and locking devices for drive- and automation engineering. High quality products by KBK are now sold worldwide in more than 45 countries.

KBK Antriebstechnik GmbH was founded in 2003 by Robert Karpstein and Bernd Brenner, in rented rooms in Trennfurt, Furtwänglerweg #30. Both shareholders contributed years of experience and a profound knowledge to the start-up of the company. In the beginning of 2011, after a continuous growth of 8 years, it was about time for a spatial enlargement. A move to Röllfeld, Unterlandstraße 46 and an expansion of machinery was necessary.

A change of generation was inevitable at KBK as well. In 2013, Mr. Robert Karpstein retired and handed over the management to his son Sven Karpstein, a graduate engineer. The senior partner will remain in the company both with his expertise and in advisory capacity. Our dedicated employees as well as the good working atmosphere are a significant part of the company´s success. KBK has been able to drive its growth and now employs an approximate local staff of 30 people. For this reason, we sponsor local projects like holiday games and kindergartens. With further planned expansions, we want to increase our market share and establish our position on the world market.

Internationally positioned and regionally rooted – this way we keep on looking forward to a successful future.


We are a dynamic and growing company with a global nationwide distribution network. To stand out in this highly competitive market, we work on it every day to offer our customers and partners decisive advantages.
