Rod Seal Agricultural Hydraulic Cylinders Nickel-Phosphorus Alloy Plating For Agricultural Machinery

Product Information

These specialized hydraulic cylinders are engineered with a premium Nickel Phosphorus Alloy (Ni-P) plating on the piston rod, offering superior corrosion resistance and wear protection compared to traditional hard chrome. This advanced coating ensures exceptional durability in the harsh, high-moisture environments typical of agricultural applications. Equipped with high-performance rod seals, these cylinders effectively prevent fluid leakage and contamination, maintaining hydraulic efficiency and reducing maintenance downtime. Designed to meet the rigorous demands of modern farm machinery, they provide reliable, long-lasting performance for a wide range of agricultural implements.

Product Summary

This agricultural hydraulic cylinder combines strong thrust and precise control. Made of high-strength materials with sealed design, it resists dust and corrosion, adapting to harsh field conditions. Millimeter-level adjustment precision meets fine operations like seeding and header control. It features reliable structure, easy maintenance, low energy consumption and long service life. Available in single/double-acting and telescopic types, it fits tractors, harvesters and other farm machinery, providing efficient and stable power for agricultural production.

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.

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.

Product Usage Instructions

• During installation, ensure the cylinder is securely and concentrically mounted to avoid lateral forces.
• Before operation, verify hydraulic fluid cleanliness and level; system pressure must not exceed the rated value.
• Avoid scratching the piston rod during use and clean the exposed rod regularly.
• For long-term storage, fully retract the piston rod and store in a dry place.
• Routine maintenance should focus on seal condition; replace seals promptly if leakage is found.
• Do not disassemble the cylinder unless you are a qualified professional.
