Working cylinder

A working cylinder, comprising:

• a cylinder having a cylinder tube, a first closure part and a second closure part defining a cylinder interior, said cylinder tube having a first cylinder tube end and a second cylinder tube end, said first closure part being arranged at said first cylinder tube end and said second closure part being arranged at said second cylinder tube end;
• a piston unit having a longitudinal axis and defining a working chamber in said cylinder interior, said piston unit passing through the first closure part in a sliding manner and having an outer end section;
• a corrosion-resistant rod-side threaded coupling module having a threaded section and a weld-on section, said threaded section being constructed for being coupled to a device to be actuated, said rod-side threaded coupling module being welded with said weld-on section to said outer end section of the piston unit by a weld seam, said threaded section being arranged on the longitudinal axis of the piston unit.

A working cylinder, comprising:

• a cylinder having a cylinder tube, a first closure part and a second closure part defining a cylinder interior, said cylinder tube having a first cylinder tube end and a second cylinder tube end, said first closure part being arranged at said first cylinder tube end and being constructed as a guide closure part and said second closure part being arranged at said second cylinder tube end and being constructed as a base closure part;
• a piston unit defining a working chamber in said cylinder interior, said piston unit passing through the first closure part in a sliding manner and having an outer end section;
• a corrosion-resistant base-side threaded coupling module having a threaded section and a weld-on section, said threaded section being constructed for being coupled to a device to be actuated, said base-side threaded coupling module being welded with said weld-on section to an outer axial surface of the second closure part by a weld seam, said threaded section being arranged along a longitudinal axis of the cylinder.
