Excavator Parts EX40 Tensiong Oil Cylinder Assembly

Hitachi EX40 Tensioning Cylinder Assembly is a key component in the excavator’s undercarriage system, which is mainly used to maintain the standard tension of the tracks.It usually consists of a cylinder, piston, seals, hydraulic oil line and tensioning spring.Its working principle is to use hydraulic pressure to push the piston, thus realizing the tensioning operation of the tracks to adapt to different working conditions and ground conditions, ensuring that the tracks are always in a proper tensioning state, reducing the risk of track jumping, wear and derailment, and improving the stability of the excavator’s travel and the service life of the chassis components.
