For cylinders, pneumatics and hydraulics, the tube must deliver tight tolerances, controlled inner roughness and consistent quality that supports sealing and smooth piston travel.
In cylinders and pneumatic or hydraulic systems, the tube plays a decisive role in how the final component works. It is not just about dimensions: what really matters is the quality of the inner diameter, geometric stability and surface finish that let the piston work properly over time.
For this industry Rigamonti supplies a range of tube sizes with very tight tolerances, down to 0.01 mm on diameters, and inner roughness even below 0.2 µm — properties that make a real contribution to sealing and smooth travel.
In these applications any variation can mean loss of efficiency, wear, friction or functional problems. That is why control of the inner surface, batch repeatability and process consistency are core requirements, not extras.
Rigamonti supplies this field around the customer's real needs, focusing not just on the nominal dimension but on how the tube actually behaves inside the system.
Three levers we use to ensure sealing, smooth travel and repeatability over time.
Inner diameters controlled to very tight tolerances, where any variation turns into wear or loss of efficiency.
Refined inner surfaces that support sealing and smooth travel, reducing friction and functional problems.
Geometric stability and process consistency, because the piston must work properly in every series.
Tight tolerances and refined inner surfaces for reliable long-term performance.
