Hydraulic Cylinder Tubes and Piston Rods
Tubes for Hydraulic Cylinders manufacturing
The tube is one the most important elements in production of hydraulic cylinders. High precision of internal diameters is provided by the using several methods of mechanical processing, such as honing and skived roller burnishing. High precision and roughness of internal surface provides smooth movement of the piston with sealing elements and reduces wear of the working elements of the cylinder. Also, the tube should have enough strength, since it will be affected by the high pressure from inside. Standard tubes are produced from materials such as St52 BK+S and analogues, internal diameter tolerance is H8, roughness of internal surface Ra0.4 – Ra0.8 depending on the tube diameter. Chrome plating can be applied according to client’s requirements.
