Product Description:

The honed tubes undergo a surface treatment process, which can be honed, smooth, skived & roller burnished. The honing process results in a surface roughness of 0.2-0.4μm, which is critical for ensuring optimal performance. The smooth surface reduces friction and wear, while the skived & roller burnished surface provides a high degree of strength and durability.

The honed tubes are made using the cold drawing process, which involves pulling the material through a die to create the desired shape. The honing process then smooths the surface and removes any imperfections, resulting in a high-quality product that is suitable for a wide range of applications.

Overall, the hydraulic honed tube is an essential component in many cylinder applications, providing a reliable and high-performance solution for hydraulic and pneumatic systems. Whether you need a honed steel tube for a small oil cylinder or a large telescopic cylinder, our honed tubes are designed to meet your needs.
