The honed tubes of Changzhou Shuangfa Hydraulic Technology Co., Ltd. play a crucial role in hydraulic cylinders. The performance of a hydraulic cylinder largely depends on the quality of the cylinder barrel. As a high-quality cylinder barrel material, the honed tubes, with their high-precision inner holes, ensure the smooth movement of the piston in the cylinder barrel and reduce frictional resistance. The uniform inner surface reticulation is beneficial to the distribution of lubricating oil, reduces the wear between the piston and the cylinder barrel, and prolongs the service life of the oil cylinder. In addition, the good sealing performance of the honed tube prevents the leakage of hydraulic oil and ensures the stability of the output force of the oil cylinder. In the manufacture of various hydraulic cylinders, selecting the honed tubes of the company can significantly improve the overall performance of the oil cylinders.
