High-Performance Rod Sealing Systems

For linear, dynamic sealing applications

To achieve the best dynamic sealing performance, the following needs to be taken into consideration: 


When the rod extends past the rod seal, a thin film of oil remains on the rod trapped in microscopic surface imperfections. The thickness of the oil film depends on the surface finish, rod seal design and surface speed of the rod. During the return stroke, this thin film can be removed by an aggressive wiper lip, resulting in system leakage.  Therefore, it is important to properly pair the wiper and the rod seal to minimize leakage and to achieve the best dynamic sealing performance. The properly selected sealing components comprise a sealing system. Some examples are listed below.
