Telescopic Hydraulic Cylinder DX255LC Excavator Hydraulic Cylinder Bucket Cylinder 

Excavator Hydraulic Cylinder Introduction

The Doosan DX255LC bucket cylinder is the core actuator in the hydraulic working device of this 25-ton crawler excavator. It is a typical double-acting hydraulic cylinder, using alternating hydraulic oil supply to both sides of the piston to achieve precise opening and closing of the bucket, digging, and unloading. The cylinder body and piston rod are made of high-strength steel and have a built-in buffer mechanism to effectively absorb operational impacts, reduce vibration, and extend the life of seals and structural components. Together with the boom and stick cylinders, it forms a complete working device, directly affecting the machine's digging force, operating efficiency, and reliability. It is a key component in daily maintenance and parts replacement.

Excavator hydraulic cylinders are our specialty. We can supply hydraulic cylinders for various brands of excavators without affecting the normal operation of the machinery. If customers have additional requirements, we have professional technicians who can modify the cylinders according to their needs and propose suitable solutions.

Excavator Hydraulic Cylinder Advantages

• Dual-acting design: The hydraulic oil can be driven in both directions, enabling precise and powerful opening and closing of the bucket and digging actions, with fast control response and high operating efficiency.
• High-strength materials: The cylinder body and piston rod are made of high-strength steel, with strong resistance to bending and impact, suitable for high-intensity, long-term heavy-duty operations.
• Built-in buffer mechanism: Buffer devices at both ends effectively absorb operational impacts, reduce vibration and noise, protect seals and structural components, and extend service life.
• Excellent sealing and reliability: Employs a high-quality sealing system with minimal leakage, wear resistance, and longer maintenance intervals, reducing downtime and operating costs.

FAQ

Q: Are the bucket cylinders double-acting or single-acting?

A: They are double-acting hydraulic cylinders. Oil can enter both the rod-side and rodless sides. The piston rod can actively extend and retract, precisely controlling the bucket's inward and outward tilting.

Q: How to determine if replacement is needed?

A: If oil leaks, sluggish operation, lack of power, abnormal noises, or obvious scoring or bending of the piston rod occur, it is recommended to check and replace or repair it promptly.

Q: What precautions should be taken during replacement?

A: Confirm that the machine model and part number match. After replacement, bleed the system of air, check the hydraulic oil level and cleanliness, and adjust the buffer effect according to specifications.
