OEM Quality

A1-Hydraulics GmbH A1-Hydraulics GmbH has been supplier to well-known machine manufacturers since its foundation, thus our customers benefit from the related quality and expert knowledge.


As early as 1976 the company’s founder Hans Günter Ley started his career in hydraulics. Drawing on more than 30 years sales experience in the hydraulic industry Hans Günter Ley founded A1-Hydraulics GmbH in 2004 in Radevormwald, Germany. Soon, significant milestones in the company’s development followed. In 2007 A1-Hydraulics GmbH moved to new company premises; today’s headquarters. In 2012 and 2013 followed the expansion of storehouse and production hall. In the following year the product range was extended significantly by launching the production of hydraulic hoses. After Mr. Ley's death in 2018 his daughter Jennifer Grabowski took over A1-Hydraulics' management in order to continue her father's life work. Today’s interdisciplinary team of professionals improves steadily the company’s service and quality.
