Excavator series hydraulic cylinder are dual-acting single-piston hydraulic cylinders developed and manufactured independently by shandong tianyi hydraulic science and technology Co., Ltd., which are the actuator of reciprocated linear motion in hydraulic system of small-scale excavators, featuring high working pressure, reliable performance, easy disassembly, easy repair, and equipment of buffering device.

It adopts the imported PARKER seals and the cylinder sleeve adopte the alloy steel, featuring high strength. The piston rod is hard chrome plated after the surface quenching treatment, with floating buffering devices at both ends, which features excellent buffering performance, effectively reduces the noise and impact load, and prolong the machine life.
