Excavator hydraulic cylinder is a key actuator in an excavator's hydraulic system. It converts hydraulic fluid pressure into linear mechanical force and motion, enabling the movement of the boom, arm (stick), and bucket.
The performance and accessories of Runhe hydraulic cylinder can be fully compatible with major brands of excavators, which can make your maintenance more convenient and cheaper.
Excavator hydraulic cylinders are critical linear actuators that convert hydraulic energy from the pump into powerful mechanical force and motion. They are responsible for nearly all the machine's primary digging and movement functions.

1,Q: What are the core advantages of hydraulic Cylinder ?
A: High working pressure, large torque, good low-speed stability, suitable for high-pressure and heavy-load scenarios.
2,Q: Do hydraulic piston motors support bidirectional rotation?
A: Yes, forward/reverse rotation can be achieved by switching the inlet and outlet ports.
3,Q: What is the typical working pressure range?
A: Normally 25-40MPa; some high-pressure models can reach over 50MPa.
4,Q: Will "crawling" occur during low-speed operation?
A: No, the piston structure design ensures stable output at low speeds.
5,Q: How to choose the suitable displacement of the piston motor?
A: Match displacement by calculating with system flow, required output torque and speed demand.
