Cylinder tube ST52.3 DIN2391 ISO H8. Piston rod 42CrM04 induction hardened, Chrome 25 µm.
Only welding on the rear end and the piston rod end is permitted on this cylinder type, otherwise there is a risk welding will make the cylinder tube oval. The piston rod must be drawn out to its outermost position in order to protect the seals in the cylinder from heat with all welding. Also take care to protect the piston rod from weld spatter.
