Main Applications of Honed tubing
Honed tubing and skived and roller burnished tubes are frequently used as cylinder tubes, such as hydraulic cylinder tubes and pneumatic cylinder tubing, for manufacturing and repairing hydraulic and pneumatic cylinders. The precise dimension tolerance and polished surface of honed tubes make them perfect for applications that demand accuracy and high surface quality. In addition to cylinder tubes, honed tubes are also suitable for a variety of other uses, including Precision Mechanical Tubes, Hydraulic Cylinders, Multi-Joint Tubes in construction, Steel Axis Pipes, Injection Machines, Robotic Arms, and more.
Our factory manufactures a broad range dimensions of cylinder tubes to meet both metric and imperial dimensions.
- Metric dimension honed tubes:
Available in I.D sizes from 30 mm to 800 mm and wall thicknesses from 3 mm to 50 mm. - Imperial dimension (inch size) honed tubes:
Available in sizes ranging from 1.5″ to 30.0″ I.D and wall thicknesses from 1/8″ to 2″. - Length:
We provide the option of either random or fixed lengths up to 14 meters for both metric and imperial dimensional honed cylinder tubes.

Advantages of Our Honed tube
Our honed tubes offer a multitude of advantages that set them apart from other options on the market.
- Firstly, our honed tubes boast high precision tolerances, meeting ID tolerance H7, H8, H9, and more, tailored to the specific requirements of our customers. This level of precision ensures a perfect fit and performance in hydraulic cylinder applications.
- Furthermore, our honed tubes are crafted from seamless cold drawn tubes, providing exceptional high pressure resistance. This feature guarantees the reliability and durability of our honed tubes, making them the ideal choice for applications where pressure is a key consideration.
- In addition to their high pressure resistance, our honed tubes also feature a smooth inside surface with a maximum roughness of Ra 0.4 microns ID finish (16Max Ra ID Finish). This smooth surface reduces friction and wear, prolonging the life of the hydraulic cylinder and enhancing its performance.
- Moreover, we offer flexible order quantities, accommodating even single unit requests for hydraulic cylinder tubing production and supply. This flexibility allows our customers to order the precise amount they need, reducing waste and ensuring cost-effectiveness.
- Lastly, our honed steel tubing boasts excellent weldability, making it a versatile and highly useful material in the production of cylinders. This feature allows for easy assembly and customization, further enhancing the functionality and performance of the hydraulic system.
In conclusion, our honed tubes offer a combination of precision, durability, performance, and flexibility that make them the top choice for hydraulic cylinder applications.

Honed tubes of material E355
E355 honed pipes are cylinder tubes honed from steel tube grade E355 and in compliance with EN 10305-1 standard. This material is the equivalent of ST52 / St52.3. 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.
Here below is the specification of the steel E355.

Packing method of Honed tubes
Protecting and securing a honed tube during transportation and storage is crucial to ensure it arrives undamaged and in good condition. There are various packing methods available for hydraulic honed cylinder tubes, each designed to provide adequate protection from impact, abrasion, moisture, and dust.
One common packing method involves placing the honed tube inside a wooden crate that is specially designed to fit its size and shape. The crate is then secured with screws or nails to prevent any movement during transit. Another option is to wrap the honed tube in steel banding, which is tightened using a ratchet tool to provide additional protection.
For added protection from moisture and dust, the honed tube can also be covered in plastic wrap before being secured with steel banding or tape. Alternatively, the tube can be placed inside a large plastic bag, which is then sealed and secured.
It is important to note that before packing, each honed tube should be oiled to prevent rusting. The specific packing method chosen will depend on factors such as the size and weight of the tube, the shipping distance, and any specific requirements from the customer. By selecting the appropriate packing method, the honed tube can be safely transported and stored until it is ready for use.
Our factory specializes in producing top-quality honed tubes and hydraulic cylinder honed tubes using our unique “Suitable To Hone” Cold Drawn Seamless Steel Tubes (CDS tubes). Through a meticulous honing process that utilizes abrasive polishing stones and paper, we are able to achieve precise ID dimensions and a smooth inner surface. In addition, we also utilize the SRB (skiving and roller burnishing) process to ensure extra precision in our honed tubing.
Our specially designed Honed tube for hydraulic cylinder is ready to be used directly in hydraulic cylinder applications, eliminating the need for further internal diameter (ID) processing. This not only saves time but also reduces costs for the production or repair of hydraulic cylinders.
