Buffer Ring PU

Buffer Rings (HBY, HBTS) are mainly installed on the pressure side of the Piston Rod Seal. The buffer rings literally help improve the durability of the piston rod Seal and play three roles:
Buffer the impact pressure generated by the piston rod side of the hydraulic cylinder, and relieve the back pressure
Prevent the oil temperature from being directly overheated to the seal, which will lead to the deterioration of the seal, and play the role of buffering and slightly cooling.
Reduce the friction resistance of the piston rod seal and the sliding and heating of the seal during the movement of the oil cylinder.
