21 Mpa Push Pull Hydraulic Cylinder Flange Mounting Style For Planting Machinery

Product Information

Built to handle up to 21 MPa of operating pressure, these push-pull hydraulic cylinders are engineered specifically for the precision demands of modern planting machinery. The flange mounting style provides a rigid, stable connection, ensuring accurate positioning of seed metering systems, row units, and depth control mechanisms. Their robust construction and high-quality seals deliver reliable performance in dusty, high-vibration field conditions, minimizing downtime during critical planting windows. Designed for easy installation and long service life, these cylinders help maintain consistent planting depth and spacing, directly contributing to improved crop establishment and higher yields.

Product Summary

Our agricultural hydraulic cylinders are high-performance and durable, suitable for tractors, harvesters, planters and other farming equipment. Hard-chrome plated rods ensure wear resistance, while multi-layer seals achieve zero leakage. They deliver stable thrust up to 50 tons with precise control, withstand dust and moisture, and support custom strokes and sizes. ROHS-certified with a 12-month warranty, they optimize agricultural machinery’s lifting, tilting and adjustment operations.

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.

Precautions

1,Safety Factor: Actual operating pressure should be ≤80% of rated pressure; impact loads require additional consideration.

2,Stability Verification: Long-stroke hydraulic cylinders require verification of the longitudinal bending strength of the piston rod under pressure.

3,Installation Alignment: Avoid lateral loads, as these will significantly reduce seal life.

4,Heat Dissipation and Maintenance: Monitor temperature rise during high-frequency use and regularly check the seals and oil condition.
