About us

Vision and goals

A one-stop shop for hydraulic equipment - A1-Hydraulics GmbH was founded with this idea in mind.

Based on his decades of sales experience, Hans Günter Ley had the vision to offer his customers all hydraulic components for their production from a single source in order to better match the products, facilitate communication and shorten delivery times.

That's why today you will find not only system solutions, but also a wide range of individual components from various manufacturers as well as industry-related complementary products. We also offer additional services such as product stocking, just-in-time delivery and product pre-assembly. As a result, we reduce your procurement times and help optimize your production process.

The wide range of products we offer includes both quality goods from various well-known brand manufacturers as well as less expensive, but equally effective alternatives.

Since competent technical advice is indispensable in the hydraulics industry, A1-Hydraulics GmbH has made it its goal to offer you not only quality but also the best possible advice. Therefore, our sales team consists of technicians from different fields. Whether you have questions regarding hydraulic, mechanical or electrical applications, our industrial mechanics, mechatronics and electronics engineers will be happy to provide you with expert advice.



Back in 1976, company founder Hans Günter Ley began his career in the hydraulics industry. With almost 30 years of experience in the distribution of hydraulic components, Hans Günter Ley founded A1-Hydraulics GmbH in Radevormwald in 2004.

Further milestones in the company's history quickly followed, and in 2007 A1-Hydraulics GmbH moved into a modern new building, its current headquarters.

This was followed in 2012 and 2013 by the expansion of the warehouse and production hall through an extension.

In 2015, the product range was significantly expanded by the introduction of our own production for hydraulic hoses.
