Our Hydraulic Cylinder Hard Chrome Plated Piston Rod, Metric Round Honed Tube, Carbon Steel Cold Drawn Tubes has earned the praise and support from customers with its superior quality, sensible price, integrity and excellent service. Above all, we are here to welcome your inquiries for any of our goods and service. We sincerely welcome friends from all over the world to cooperate with us and enlarge our business.

High precision hydraulic cylinder tubes uses a kind of low cost process to obtain high inner hole gauge and quality, which can not only effectively reduce the surface roughness of inner hole, but also strengthen the surface of inner hole, improve the hardness of inner hole gauge and extend the fatigue life of tubes. The inner hole of many oil cylinders adopts this process now. After skiving and roller burnishing, the surface roughness can be reduced by 2 to 3 grade. The process has good applicability for carbon steels which has low hardness and good plasticity.

Features:

We are a manufacture which can supply products and services from raw material to hydraulic cylinders and machines, including acid pickling, parkerising, saponification, cold drawing, quenching, stress annealing, honing, welding, precision machining and other processing

With mighty technical support, powerful design and development ability, we are at the front of this field and receive many good reputations

We can produce large cylinder tubes which can be 1200 mm for ID and 1600 mm for OD and the longest can reach 16 meters for length.

Mechanical properties

Advantages:

1. Improve the surface roughness which can reach under Ra 0.08um.

2. Corrected roundness and ovality.

3. Improve the surface hardness and eliminate the stress deformation.

4. Improve the quality and abrasion then extend the service life of parts and reduce the cost.

Application: Our honed tubes are widely used as mechanical tubing, pressure tubes which require a heavier wall thickness.And also they are used for producing hydraulic cylinder tubes.
