60-Ton Double-Acting Hollow Hydraulic Cylinder

. 60-Ton Double-Acting Hollow Hydraulic Cylinder is a high-performance center hole hydraulic jack designed for applications requiring both pulling and pushing force through a hollow piston structure.

Its double-acting design allows hydraulic power to control both extension and retraction, ensuring faster operation, higher precision, and improved efficiency in industrial lifting, tensioning, and maintenance work.

The center-hole structure makes it ideal for bolt tensioning, cable pulling, and threaded rod applications where a solid cylinder cannot be used.

Working Principle

The cylinder operates using hydraulic pressure on both sides of the piston. Oil pressure extends the piston rod for pushing or tensioning, while reverse pressure actively retracts it, allowing faster and more controlled operation.

. hollow center design enables the cylinder to work directly on threaded rods or cables, making it essential for tensioning systems and structural tightening applications.

Quality Control

Each unit is strictly tested before delivery:

• 1.5× pressure load testing
• Leakage testing under full working pressure
• Stroke and retraction speed test
• Center alignment inspection
• Seal durability and fatigue test
• Surface hardness and coating inspection
