Datong Hydraulic

Hydraulic cylinder tube is one typical application type of honed tube. It is made from cold drawn seamless steel tube (CDS tube), by the process of honing or Skiving & Roller Burnishing (SRB tube) on the inside surface. It is widely used to manufacture hydraulic cylinders, so it is known as hydraulic cylinder tube.

As the most experienced hydraulic cylinder tube supplier and manufacturer, we can understand the requirements of our customers accurately, and we can give our suggestions to our customers to help them to choose the right materials and the hydraulic cylinder tube sizes.

Here below are the main features of our hydraulic precision cylinder tubes.

  • Tolerance 

Our cylinder tubes with high accuracy tolerance can be provided by us at premium cost, mostly the tolerance of the honed tube ID is ISO H8; and we also can manufacture hydraulic cylinder tubes with ID tolerance H7 or H9 on customer’s request.

  • Ovality 

The ovality of cylinder tube is over the limitations of ID tolerance.

  • Eccentricity  

The eccentricity of honed cylinder tubing is highest 10 percent of the wall thickness based on EN 10305-1.

  • Surface Roughness  

Inner surface Roughness for SRB finished cylinder tubes is Ra = maximum 0.25 µm. for cylinder tubes; and with Honing finished the roughness is Ra = maximum 0.40 µm.

  • Weldability  

Weldability of our hydraulic honed tubes SRB completed or Honed is superb.

  • Machinability 

The machinability of our hydraulic honed tubes SRB completed or Honed is superb.

  • Ready to use 

Our factory’s honed cylinder tubing is prepared to use to manufacturing hydraulic cylinders without additional inside diameter processing.

Sizes of Hydraulic cylinder tubes

As one of the leading honed tube suppliers, all honed cylinder tubing of our factory is offered in both metric and standard sizes and may be cut to length to meet customers’ requirements.

The size range of our hydraulic cylinder tubes: metric size ID. 30mm – 1500mm, wall thickness 4 mm -32 mm. or standard size 1.0″ ID – 20.0″;  wall thickness 1/8″ – 1″.

Materials

As one of the main hydraulic cylinder honed tube suppliers and manufacturers, our factory produces honed precision cylinder tubes in full range of steel grades, such as SAE 1020, 1026, St 52, ST52.3, st 52.4, ST35, ST37.4, E255, CK 35, China 20# steel, China 45# steel, and so on.

Besides Honed Tubes, Our Datong Hydraulic also manufacture hydraulic cylinder chrome plated bar,hollow chrome bar,induction hardened chrome bar.we had become one of the most famous hydraulic cylinder tube  and rods suppliers,manufacturers in the market.
