The EPYY11112017 Towing and Lifting Cylinder is a specialized high-performance component designed for the front-end attachments of modern agricultural machinery. Primarily mounted on combine harvester headers, it facilitates the dynamic tilting and height adjustment required to follow uneven field contours. This Agricultural Towing Cylinder is the key to maintaining optimal cutter bar height.

Despite its compact 6kg frame, this cylinder is built for industrial-grade endurance. It serves as a high-precision aftermarket replacement for flagship harvesting equipment, offering superior response times and corrosion resistance compared to standard OEM units. Its 348mm stroke is meticulously calibrated for the quick lift actions needed to avoid ground obstacles during high-speed harvesting.

The EPYY11112017 operates as a double-acting, fast-cycle hydraulic actuator. In agricultural header applications, it is typically mounted on the feeder house or lift frame to control the vertical positioning of the cutting platform.

Hydraulic Dynamics: When 16.7MPa of pressure is applied to the Φ40mm bore, the rod extends through its 348mm stroke to lift the header. The integrated manifold ports are designed for zero-restriction flow, allowing for the near-instantaneous height adjustments required when harvesting at high speeds in uneven terrain.

Blueprint Anatomy: The CAD drawing highlights the 536mm pin-to-pin install profile. It features heavy-duty trunnion or spherical mounting points to absorb the dynamic oscillations and vibrations inherent in field harvesting. The rod is fitted with specialized multi-lip wipers to prevent corn husks and wheat dust from entering the seal housing.

Ultra-Rapid Response

The Φ40mm bore is optimized for low fluid volume and high speed, allowing for the split-second header height adjustments needed to maximize grain recovery in undulating fields.

24.5MPa Safety Buffer

Agricultural equipment faces sudden mechanical impact. Our 24.5MPa withstand rating protects against barrel swelling when headers strike ground obstacles.

Zero-Drift NOK Sealing

Utilizing Japanese NOK multi-lip seals, this cylinder eliminates internal fluid bypass, ensuring the header maintains its exact height with zero downward creep during operation.

Featherweight Precision (6kg)

The ultra-compact 6kg build minimizes the parasitic weight on the combine’s front axle, reducing soil compaction while providing industrial-grade lifting power.

Agricultural headers are abrasive, dusty environments. As a premier Agricultural Machinery Cylinder Manufacturer, we utilize ST52.3 (E355) precision cold-drawn tubing to ensure the EPYY11112017 outlasts the harvest.

The Φ40mm internal bore is CNC skived and roller-burnished to an Ra 0.2µm finish. This minimizes dynamic friction during the 348mm strokes, drastically extending seal life even in high-heat harvesting conditions.

• Quenched Φ25mm Rod: Forged from high-tensile 45# carbon steel, induction-hardened for impact resistance, and coated in 40µm of hard chrome.
• Multi-Lip Dust Wipers: Specifically designed to block organic ag-debris and fine wheat dust from infiltrating the primary seal matrix.
• 100% Quality Validation: Every 6kg unit undergoes a severe 24.5MPa hydrostatic hold test before dispatch to verify weld and seal integrity.
