Friction optimization on hydraulic piston rod seals

摘要

Everywhere, where high forces have to be transmitted and linear movements have to be performed, the use of hydraulic cylinders is a common praxis. In this case the so called "characteristics of convenience" are getting more and more important for the operators of modern hydraulic systems. In first line the friction performance of rod and piston seals has to be stated. High friction forces will cause a higher use of energy connected with a worse degree of efficiency. High friction can create also a higher wear on the used seals and this will result into a significant reduction in life time of the hydraulic system.
