Rod Seals Introduction.
Update:2016-03-11
The Rod seals is designed to ensure that pressurized fluid does not leak out of the system as the rod cycles back and forth out of the gland (dynamic pressure sealing).
The rod seal is the most critical seal on any type of fluid power equipment. A leaking Rod seals not only reduces equipment performance, but also causes environmental issues. Our rod seals are available for both:
- single-acting: capable of sealing dynamic pressure from one side (unidirectional)
- double-acting: capable of sealing dynamic pressure from both sides (bidirectional)
Particular attention should be paid to selecting the best rod seal for your application. It is important to properly pair the rod seal and the wiper for the best sealing performance. If a less aggressive Rod seals is paired with an aggressive wiper, the wiper can scrape off the microscopically thin film of oil that remains on the rod in microscopic surface imperfections during the return stroke, resulting in system leakage. The thickness of the oil film depends upon the surface finish, Rod seals and surface speed of the rod.
