Excavator Parts EX15/17 Tensiong Oil Cylinder Assembly

Hitachi EX15/17 Tensioning Cylinder Assembly is an important part in the traveling device of the excavator, which is mainly composed of cylinder barrel, piston, piston rod, seals, springs and so on.Its working principle is that by injecting grease into the cylinder, increasing the oil pressure to push the piston and piston rod to extend, so as to tension the tracks; when it is necessary to relax the tracks, release the grease, and under the action of the spring and other components, the piston rod retracts.The function of this tensioning cylinder assembly is to maintain the proper tension of the track, make the excavator travel smoothly, reduce the wear of the track and the risk of derailment, and ensure the normal operation of the excavator.
