Excavator cylinder piston seals SPGW -Green

Due to the special working environment of construction machinery, its hydraulic system has the following characteristics: Irregular working hours, sometimes working continuously for long periods of time, The working environment is outdoors, with a large temperature difference and a lot of dust; Due to size and weight constraints, hydraulic tanks are usually relatively small when the machine is traveling by itself. Due to the size and weight, the working pressure of the hydraulic system is relatively high, usually above 20MPa, up to about 40Mpa.
