An Empirical Study on the Wear of Reciprocating Hydraulic Rod Seals Using 15 Different Oils

Hydraulic oils differ in their chemical composition and viscosity substantially. Their influence on the wear of rod seals is neither fully understood nor can be predicted precisely. The primary objective this study was to evaluate various wetting properties seals. In an empirical study, 30 commercially available polyurethane U-cups investigated with 15 different using a recently built test rig. increased lower higher polarity oil. Both oil are combined new parameter which helps assess lubricity
