Flange Connection Agricultural Hydraulic Cylinders Trunnion Mount For Fruit And Vegetable Harvester

Product Information

Our flange connection hydraulic cylinders with trunnion mount are specifically engineered for the precise demands of fruit and vegetable harvesters. This robust dual-mounting system combines the stability of a flange with the pivotal flexibility of a trunnion, ensuring optimal alignment and force transmission during delicate picking and sorting operations.

Manufactured with food-grade compatible seals and corrosion-resistant finishes, these cylinders maintain operational integrity in high-moisture, washdown environments. The design minimizes stress concentrations during articulated movements, extending service life while providing smooth, responsive control for conveyor adjustments, header positioning, and bin-handling mechanisms.

Product Summary

This agricultural hydraulic cylinder is a core power component for tractors, harvesters and other farm machinery, available in single/double-acting and telescopic types. Made of high-strength materials with precision sealing design, it resists dust and muddy water corrosion, adapting to harsh field conditions. It delivers strong thrust and millimetric control precision, enabling accurate operations like lifting and depth adjustment. With reliable structure and easy maintenance, it combines long service life and cost-effectiveness, providing stable power for plowing, seeding, harvesting and more to boost agricultural productivity.

Product Parameter Table

Product Application

Agricultural hydraulic cylinders are widely used in tractors, harvesters, loaders, etc. They lift farm tools, tilt hoppers, and adjust agricultural machinery arm angles, enabling automated sowing, fertilizing, and harvesting. Boosting field work efficiency by over 30%, their dust-resistant and corrosion-proof features suit damp, muddy farm environments. They are core power components for modern agricultural mechanization.

Product Advantages

The core advantages of agricultural hydraulic cylinders are large output thrust, adaptation to harsh working conditions, precise control and strong durability.

1. High Thrust & Efficiency. It can output strong power with a small size, easily driving heavy-duty operations such as plowing, harvesting and lifting of agricultural machinery.
2. Weather & Contamination Resistance. It can adapt to harsh field environments like dust, muddy water and large temperature differences, and the sealing design can effectively prevent impurity intrusion.
3. Precise & Stable Control. Flexible adjustment of stroke and speed enables precise completion of fine operations such as seeding depth control and header height adjustment.
4. Low Maintenance Cost. The simple and reliable structure allows easy replacement of wearing parts, with low failure rate during long-term use, suitable for the high-frequency operation needs of agricultural machinery.

Production Theory

Based on Pascal's principle, agricultural hydraulic cylinders achieve linear reciprocating motion via hydraulic oil pressure transmission: The cylinder barrel (high-strength steel with precision grinding) and piston rod (hard chrome-plated) form a sealed chamber. When the hydraulic pump inputs pressurized oil, the piston is pushed by oil pressure to drive the rod’s extension/retraction, outputting thrust. Production involves welding, honing, and seal assembly; key processes include precision grinding of the cylinder inner wall (accuracy ≤0.02mm) and chrome plating of the piston rod for rust resistance. Finally, pressure testing (≥25MPa) ensures pressure resistance, suitable for heavy-load, dusty farm work scenarios.
