The unreasonable parts of cylinder design for ZZ8500/20/40 hydraulic support are improved. The processes of processing middle cylinder according to the original design and the improved design are listed respectively and compared. Design process before improving is cumbersome, time-consuming and inefficient; Improved design process saves both labour and material, can reduce cost and increase the efficiency by 50%.
