Cylinder tubes, piston tubes and piston rods

Low dimensional tolerances. Low eccentricity. A high degree of straightness. These are the main characteristics of our cylinder tubes, piston tubes and piston rods. In addition, their surface is characterized by low roughness values and is particularly resistant to corrosion.

If you are a manufacturer of hydraulic and pneumatic cylinders and depend on high quality for your products, then BENTELER is your best choice: we can provide a wide range of cylinder tubes, piston tubes and piston rods. And the best thing is that you can even get the products prefabricated.
