Cylinder tubes, piston rods and piston tubes

Seamless cylinder-tubes and piston rods

Cylinder tubes are cold-drawn tubes with a reworked inner diameter to achieve a tolerated fit according to the ISO standard. 

Hard chromium plated piston rods and piston tubes are the counterparts which meet the requirements of the ISO standard with regard to outside diameter.

These ready-to-install components are used in hydraulics and pneumatics.
