Leader of Turkey in the field of Hydraulic Cylinders since 1950

Chief of the Board & CEO


CEO Message

Our industrial hydraulic cylinders are built to work in the toughest conditions. Developing solutions in partnership with our customers has allowed us to continually create and expand our portfolio of hydraulic cylinders that meet global safety standards for any environment you work in.

Kayahan engineers and manufactures the hydraulic cylinders more capable for safety and reliability. This gives you smarter, cost-optimized solutions with an extended lifecycle and intelligent components.

Standard Model physicist Steven Weinberg, who passed away in 2021, says, “If a horse breeder looks at a horse and says it is beautiful, he does not say it out of aesthetic concerns, he has seen and trained many horses, and he knows from experience that this horse can win a race.” Craftsmanship is like this in industry; It is possible to do your job with love and care by using the experience of years and to transfer what you know to future generations. Our aim is not only to produce cylinders, but also to prove that every stage of production can be done with respect to the environment and people, protecting its stakeholders, honest and profitable.

We will continue to manufacture with the same responsibility and discipline as we learned from our ancestors.
