Single Acting Cylinder Tubes are the one of the most important part in telescopic hydraulic cylinder working system.Single-acting telescopic cylinders use hydraulic power to extend the cylinder and gravity or mechanical force to retract the cylinder into its original position. This design is low-maintenance and compatible with most machinery. Double-acting telescopic hydraulic cylinders utilize unidirectional hydraulic power to extend and retract the cylinder. This telescopic cylinder design is best for heavy-duty applications.  these telescopic cylinders  have super processing requirements, and its inner surface roughness is required to be max Ra0.4 microns, and the requirements for coaxiality and wear resistance are strict. Generally, it is processed and produced by the principle of honing or rolling. As a experienced manufacturer of different kinds of telescopic cylinders, Wuxi YUTONG is very clear about  that the common materials of single acting cylinder tubes are ST52/ST52.3 ,
