Product Show :

The working condition of the excavator cylinder is very bad. The main performance is as follows: the working pressure of the hydraulic system is large; the impact pressure is relatively high; the lateral load is large; the working temperature and the moving frequency are relatively high. Therefore, the performance of the excavator cylinder will have a direct impact on the quality of the entire machine.

Excavator cylinder components mainly include: cylinder, cylinder low, piston, piston rod, buffer, external seals and standard parts.

The hydraulic excavator hydraulic cylinder includes three parts: the boom cylinder, the arm cylinder and the bucket cylinder, and four cylinders. Since each cylinder directly controls its working device, its movement is frequently reciprocated in a large thrust range, and most of them have no outer protective device. Therefore, the failure rate is high in the entire hydraulic system. Different parts of the cylinder seal are not the same, mainly including oil seal, Glyd ring and O ring.
