Maintenance of piston rod

The outer diameter difference of the piston rod can have a small gap on the circular diameter of the bearing, but under the precise movement, we can adjust the tolerance of the solid shaft, so that there will be no pressure and gap. If the roundness and straightness of the shaft are not good, pressurize the solid shaft periodically, which can not only reduce the service life, but also can not do linear movement. Therefore, we must pay attention to the selection. If the piston rod changes color, it means that the system has a high temperature.

In winter, the piston rod will drop sharply in high temperature and low temperature environment. If other brands of hydraulic oil are used during maintenance, discoloration will not occur in a short time, because extreme pressure and anti-wear additives are added to the oil. If the temperature of piston rod is not well controlled, the electroplated coating will crack.
