Runhe hydraulic cylinders are specially developed for seed drills, serving as key actuators for frame lifting, row-unit depth control and marker folding. Designed for frequent short-stroke cycles in seeding seasons, they endure fine soil dust and field vibration. They coordinate precisely with seeder hydraulic circuits to maintain consistent sowing depth, avoid seed waste and support custom sizes for different no-till and precision seeders.
Optimized for precision seeding tasks, these cylinders run steadily on uneven farm ground with fine dust and loose soil. The honed tube and hard-chromed rod resist abrasive soil particles. Fine-dust exclusion seals prevent soil ingress. Smooth, sensitive movement keeps consistent opener penetration depth, ensuring uniform seed placement. They fit multiple seeder brands and help farmers achieve even germination with fewer field adjustments.
