New foundation


Relocation & Expansion


Generation change
Robert Karpstein / Sven Karpstein


Over 50 employees


The company KBK Antriebstechnik GmbH was founded in 2003 by Mr. Robert Karpstein and Bernd Brenner in rented premises at Furtwänglerweg 30 in Trennfurt. Both partners brought many years of profound knowledge and experience into the start-up.

After 8 years of continuous growth, it was time to expand in early 2011. Thus, a move to Unterlandstraße 46 in Röllfeld and an expansion of the machine park were on the agenda.

KBK also saw a change of generations. In 2013, Mr. Robert Karpstein retired and handed over the management of the company to his son, Dipl.-Ing. (FH) Sven Karpstein. The senior boss will remain with the company with his expertise and in an advisory capacity. 

Our strengths Your advantages

Delivery Times
Delivery times of 1 to 2 weeks are the standard and nothing special.

However, difficulties may arise during a machine standstill and possible production downtime. In this case we will help you! Due to our modular system we are able to produce almost any elastomer and metal bellows couplings from our standard program with customized bores and ship them by courier immediately. All common locking devices can be dispatched ex stock.

Prices and Quality
There is a permanent pressure to cut costs without losing a quality standard.

Due to the use of KBK-products you can save 30% on the average, compared to comparable products. Furthermore, you can be assured that all KBK-products are subject to a 100% quality control. Permanent testing in our company, as well as high-precision manufacturing, provide the basis for the top quality and durability of our products. 

Technical Service
In the relevant category, you will find links to the respective partner websites on CADENAS regarding our products.

Here you have the option to configure the desired product free of charge and download the appropriate format (3D-PDF, 2D-painting or 3D-design). We would be pleased to send you any customized designs by email at short notice. For a fast download of complete model ranges, you can log in at our download area for free to download the desired range of products.

Customized Solutions
Customized solutions for customers’ needs.

Based on our modular system we are able to realize many customized solutions fast, cost-effective and based on standard components. In case you cannot find the appropriate drive component for your application, we will face the challenge of a completely new design including the calculation and the development.

Internationally positioned and regionally connected - this is how we continue to look forward to a successful future.

Over 50 specialists are part of our team.

Our dedicated employees and the good working atmosphere naturally also account for a large part of our success. As a result, KBK has been able to continue its growth and now employs around 50 people from the region. 

That is why we continue to support local projects such as vacation games and kindergartens. With further planned expansions, KBK would like to increase its market share and further establish itself in the world market.
