Double Lip Rod Seal

Double lip Rod seal has two sealing lips. It is the most critical seal on any type of fluid power equipment. It prevents leakage of fluid from the cylinder to the outside.

Function 

Rod seal is the most critical seal on any type of fluid power equipment. It prevents leakage of fluid from the cylinder to the outside. Leakage through a hydraulic cylinder can reduce equipment performance. In extreme cases it can cause environmental issues. Particular attention should be paid to pair the rod seal and the wiper for the best sealing performance. If a less effective rod seal is used in a hydraulic cylinder, 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.

Application 

Construction machinery, fork-lift trucks, Mining machines, injection molding machines, agricultural machinery, loading platforms and standard cylinders etc.

Installation

It fits easily in closed grooves according to the sizes chart. Therefore You should use special assembly tools during installation. But, It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.
