    hydraulic cylinder tube

    Detailed Product  Description

    Based on the optimized cold drawn process and reliable raw material source, we significantly reduce

     the stock margin for the honed tubes and increase dimensional accuracy of inside and outside diameters.

     By cold drawing, it improves mechanical properties which can provide a wall thickness reductions of up to 

    30%, and leading to significant component weight reduction

      11.   Tube Ends
                      Tube ends shall cut square to the  tube axis and be free from excessive burrs. 
                 Both ends protected with Plastic caps.

                  As the result of stress relieved annealing after the final drawing, residual stresses are reduced, 

    forming within defined limits is made possible, and dimensional changes during/after machining are

     minimized.
