Continuous trends in the hydraulic world lead to a need for increased power and efficiency. Weight is a driver for that and therefore hydraulic systems are also under scrutiny for lighter weight construction. The commonly known 'stick slip effect' can occur more easily in light weight hydraulic applications, causing increased vibration and noise. Engineers typically look to overcome the problem using solutions with known materials and seal designs. However, the tribological system is complex and certain combinations of application conditions such as speed or fluid viscosity can limit the effectiveness of these solutions. This paper presents a new sealing approach which now allows the elimination of stick-slip due to an intelligent combination of materials and extends the presented and published content (1). When stick-slip situations arise at a sealing contact area, micro movements can be damped using the characteristics of an elastomer material to eliminate noise and vibration.
