Basic Functions of Rotary Shaft Seals:Retain lubricants within the system.Exclude contaminants from entering the system.Protect lubricated bearings.Withstand pressure differentials in certain applications.

Piston Seal  

Piston seals are used to create a sealed contact between the piston and cylinder. The moving piston generates high pressure on the seal, increasing the contact force between the seal and the cylinder surface. Therefore, the surface characteristics of the dynamic sealing interface are crucial for sealing performance.
 

Piston Rod Seal 

Piston rod seals and buffer seals are designed to seal the sliding motion between the hydraulic cylinder and the piston rod. Depending on the application, the sealing system may consist of both a piston rod seal and a buffer seal (commonly used in heavy-duty equipment) or only a piston rod seal.In addition to their sealing function, these components provide a thin lubricating film on the piston rod, which lubricates the rod itself and the wiper seal.
