Descriptions of Honed Tube For Hydraulic Cylinder

Our honed tubes are designed for hydraulic cylinders, offering smooth surfaces that ensure efficient piston movement. The honing process creates a polished inner surface, reducing friction, wear, and enhancing sealing efficiency under high pressure.

Made from high-strength carbon steel, these tubes are resistant to corrosion and wear, making them ideal for heavy-duty applications. Commonly used in construction machinery (excavators, loaders), agricultural equipment (tractors, harvesters), material handling (forklifts, cranes), and industrial machinery (presses, compaction machines).

Available in various sizes and customizable to fit specific hydraulic systems, seamless honed tubes improve performance and extend the lifespan of hydraulic cylinders. These tubes are designed to optimize efficiency, reduce maintenance, and ensure reliable hydraulic operation in demanding environments.

Scraping and Rolling Techniques for Enhanced Honed Tube Performance

Honed tube for hydraulic cylinder is manufactured using advanced techniques like scraping and rolling to improve their durability and performance. Scraping and rolling create a surface layer with residual compressive stress, effectively sealing minor cracks and enhancing corrosion resistance. This process delays the onset of fatigue cracks, significantly increasing the fatigue strength of the tubes.

The rolling process also forms a cold hardening layer on the inner surface, minimizing elastic and plastic deformation during contact. This improves wear resistance, reduces surface roughness, and enhances the matching properties of honed tubes for seamless integration into various hydraulic systems.

These techniques make honed tubes highly durable and corrosion-resistant, ideal for industries like construction, agriculture, and manufacturing, where materials must withstand harsh conditions and maintain superior performance.
