In mechanical components such as hydraulic cylinder, bearing and automation equipment, various types of elastomeric seals are widely used to protect leakage of lubricant or working fluid and to prevent ingression of foreign particles into the system. In this paper, a rectangular shaped reciprocating rubber seals is modeled to investigated the sealing and lubrication characteristics using a fluid-structure coupled software. For instance pressure difference, sliding speed and its direction, the hydrodynamic pressure distribution in the sealing surface, film shape, leakage flow rate between piston rod and seal are showed.
