Fully Compatible Hydraulic Cylinder Dx350 Middle Arm Are Used In Excavator 

Product description

Hydraulic cylinders are essentially double-acting hydraulic cylinders, meaning that hydraulic oil can act on both sides of the piston to achieve movement in two directions. 

Main components: 
Cylinder barrel: The main pressure-bearing tube, with high-precision and high-smoothness requirements for the inner wall. 
Piston rod: The extended part, usually hard-chrome plated on the surface to prevent corrosion and wear. 
Piston: Installed on the piston rod, it divides the cylinder barrel into the rod chamber and the non-rod chamber. 
Sealing system: including piston seals, rod seals, dust rings, etc., to prevent oil leakage and the entry of contaminants, it is the key to the service life of the cylinder. 
Guide sleeve: Supports the piston rod and ensures its linear motion. 
Oil ports: The oil inlet and return ports for the rodless chamber and the chamber with the rod.

Product Specification

Applications:

A 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.

Summary of Excavator Hydraulic Cylinder

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.

Our advantages

1. Super bearing capacity: Specially designed cylinder and piston rod, after rigorous testing, can withstand far more than 3% of the peer standard load, large mechanical operations are no problem, easy to cope with all kinds of heavy duty tasks.
2. Accurate displacement: Advanced sealing and guiding technology, the control displacement accuracy can reach ±1cm, to ensure the accurate position of the equipment during operation, to meet the needs of precision machining, positioning and other high-precision operations.
3. Long life: the inner wall of the cylinder adopts the honing process, with high-quality seals, the wear resistance and corrosion resistance are increased by 1.3 times, the maintenance frequency is greatly reduced, and the service cycle is far more than similar products, helping you save costs.
4. Fast response: Optimized structural design, the response time is shortened to 0.5s, and the telescopic action can be completed in an instant, effectively improving the operation efficiency of the equipment and making the production rhythm more compact.
5. Wide adaptation: Complete specifications and models, can be adapted to more than 95% of industrial equipment hydraulic system, whether it is mining machinery or automated production line, can be easily docking, convenient installation, ready to use.

FAQ

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.
