Honed Tube / Hydraulic Cylinder Tube Brief Introduction
Honed tube, also known as Hydraulic cylinder Tube, because honed tube is ready to use for hydraulic cylinder applications without further ID processing. Honed tubes are highly regarded in various industries. These tubes, which are either skived or roller burnished, are crucial components in the production of hydraulic cylinders. And as this kind of tubing is usually honed in the tube inside diameter, it is known as honed ID tubing also.
Guangxi, a leading honed tube supplier and manufacturer, offers high-quality steel honed tubes and skived roller burnished tubes for pneumatic and hydraulic cylinders at competitive prices. We offer both metric and imperial sizes honed tubing to meet the needs of our clients.
With almost 25 years of experience in the industry, Guangxi has been a reliable source for honed tubes for hydraulic cylinder applications. Here below are the details of our product of honed tubes.

These honed cylinder tubes are usually referred to as cold drawn seamless honed tubes, as per the EN10305-1 /E355 +SR specification. The “+SR” indicates that these tubes have undergone a stress relieved heat treatment process.

The honed tubes made from this material 27SiMn are known for their high strength and versatility in various applications.
20MnV6 hydraulic cylinder tube
20MnV6 honed tubes, made of carbon-manganese steel alloyed with vanadium, are a popular choice for hydraulic cylinder honed tubes due to their high tensile strength range of 600-790 MPa and high yield strength range of 440-650 MPa. The tubes are typically supplied in a black hot rolled condition, and are ideal for applications requiring super high strength. The combination of carbon, manganese, and vanadium makes 20MnV6 honed tubes a robust and durable choice for demanding applications.Here below is the detailed specification of steel 20MnV6

Stainless steel honed tubes
Stainless steel honed hydraulic cylinder tubes are an ideal choice for applications that demand high resistance to corrosion. These honed tubes, made of stainless steel, provide the necessary protection against harsh environments and corrosive substances. They are often used in industries such as food processing, chemical processing, and marine, where resistance to corrosion is a top priority. With their robust construction and corrosion-resistant properties, stainless steel honed hydraulic cylinder tubes are the ideal solution for applications that require high performance and durability.Stainless Steel grades for honed tubes

Honed tube Packing
The packing method of a honed tube refers to the way in which the hydraulic honed cylinder tube is protected and secured during transportation and storage. The packing method is important to ensure that the honed cylinder tube is not damaged during shipping and handling and to protect it from the elements, such as moisture and dust.
The following are some common packing methods for hydraulic cylinder tubes:
- Wooden Crate: The hydraulic cylinder tube is placed inside a wooden crate that is specifically designed to fit the size and shape of the cylinder. The crate is secured with screws or nails and is designed to protect the cylinder from impact and abrasion.
- Steel Banding: The hydraulic cylinder honed tube is wrapped in steel banding, which is tightened with a ratchet tool. The steel banding provides additional protection from impact and abrasion.
- Plastic Wrap: The hydraulic cylinder tubing is covered with a layer of plastic wrap, which protects it from moisture and dust. The plastic wrap is then secured with steel banding or tape.
- Plastic Bag: The honed tube is placed inside a large plastic bag, which protects it from moisture and dust. The bag is then sealed and secured with steel banding or tape.
These are just some of the common packing methods for hydraulic honed cylinder tubes. The specific packing method will depend on the size and weight of the cylinder tube, the shipping distance, and the customer’s requirements. And the most important is that before packing, each honed tube need to be oiled to prevent the tubes from rusty.
As a top honed tube and hydraulic cylinder honed tube manufacturer, our factory produces high-quality honed tubes using our proprietary “Suitable To Hone” Cold Drawn Seamless Steel Tubes (CDS tubes). To achieve precise ID dimensions and a smooth inner surface, a honing process is employed, which uses abrasive polishing stones and paper to remove small amounts of material. Additionally, our factory also employs the SRB (skiving and roller burnishing) process to manufacture honed tubing for extra precision.
Our Honed tube for hydraulic cylinder is specially designed to be used directly in hydraulic cylinder applications without the need for any further internal diameter (ID) processing. This saves valuable time and reduces cost for the production or repair of hydraulic cylinders.
