Honed tube for hydraulic cylinder usually is known as hydraulic cylinder tube or cylinder tubing also. It is mostly produced with cold drawn seamless tube (CDS tube) or DOM tube by honing or skiving & roller burnishing on the inner diameter of the steel tube.
Our factory is a high quality honed tube manufacturer and supplier in China. We produce and supply a wide range of honed tubes for hydraulic cylinders, with many different materials.
Product Description
Seamless steel honed tube for hydraulic cylinder have the precise tolerance.
Product Name: Honed tube for hydraulic cylinder
Also known as cylinder tube, hydraulic cylinder tubing, honed ID tubing, honed cylinder tube, and more.
Our Honed tube for hydraulic cylinder is a crucial component in various industries. Made from our factory’s own cold drawn seamless tube (CDS tube), the honed tube undergoes honing or skiving and roller burnishing processes.
