A heavy-duty hydraulic cylinder is designed for high-load, high-pressure industrial applications, delivering stable force output, long service life, and reliable performance in demanding environments. This cylinder is widely used in construction machinery, metallurgical equipment, automation systems, and industrial manufacturing.
Key Features of Heavy-Duty Hydraulic Cylinders
Maintenance-Free Self-Lubricating Design
Equipped with oil-impregnated self-lubricating bearings, the piston rod operates without external lubrication, reducing maintenance costs and downtime.
Adjustable End-of-Stroke Cushioning (Optional)
An adjustable hydraulic cushioning system minimizes impact and vibration during direction changes, ensuring smooth and stable operation.
Optional – please specify when ordering.
Multiple Mounting Configurations
Various mounting styles and accessories are available, allowing flexible installation to suit different equipment structures and working conditions.
High-Temperature Resistance (Optional)
With high-temperature-resistant seals, the cylinder can operate reliably at temperatures up to 180°C, making it suitable for harsh industrial environments.
Optional – please specify when ordering.
Magnetic Piston for Position Feedback (Optional)
A built-in permanent magnet enables compatibility with proximity or reed switches for stroke position sensing and automation control.
Optional – please specify when ordering.
Adjustable Stroke Length
An adjustable nut at the piston rod end allows fine stroke adjustment within the rated range, providing equal push and pull force (F1 = F2).
Custom & Non-Standard Hydraulic Cylinders
Based on the standard series, we offer custom hydraulic cylinder solutions, including special dimensions, mounting types, seals, and materials to meet specific customer requirements.
