About us

Klein GmbH - your reliable partner for customized solutions in the fields of hydraulics, mechanical engineering and robotics. Find out more about our expertise and corporate philosophy.

Welcome to Klein GmbH

Since 1963, we have been an established company in the manufacture of rotary unions and customized mechanical engineering components. With over 60 years of experience, we not only offer four different types of rotating unions, but also manufacture rotating unions exactly to our customers’ specific requirements. Our rotary unions enable the safe and reliable guidance of a wide range of media, such as air, hydraulic oil, emulsions, steam, water, thermal oil and many more – regardless of whether a low or high operating pressure is required, we cover it all.

Thanks to our modern CNC technology in 3-axis and 5-axis machining, we manufacture precise turned and milled parts – from simple components to sophisticated explosion-proof components. With extensive knowledge of various manufacturing processes, such as casting, extrusion and plastic injection molding, we produce components efficiently and profitably.

Our 15 machining centers and a production area of 1,800 m² enable us to implement even the most complex production orders with the highest precision. In addition to manufacturing, we also offer CAD design, assembly and prototype construction. Whether you need turned and milled parts or a complex custom-made product – we offer you tailor-made solutions. Contact us and benefit from our many years of expertise.
