As admitted in the market, composing of several parts, a cylinder steel bar plays a great roll and works well. But one problem is, as we usually find, that it’s quite easy to break, however the cause is not that easy to find. Here are some possibilities.
Check if the central body matches the cylinder satisfying the requirement standard of concentricity when installing. If not, an angle will exist between the central body and the central line of the cylinder, which will cause bending during running.
Another possibility is the existence of fluid mixed with air. The result is that the piston rod breaks at the space where cylinder fluid strikes the rod.
Unreasonable designing of cylinder and its stand can also cause damages.
If the distance of cylinder and buffer is large, the discharge of exhaust can’t be buffered. Then the cylinder will shake along with thehard chrome steel bar,which will cause deviation between concentricity of cross head the piston rod.
