Hydraulic cylinder seals are used to seal the opening between various components in the hydraulic cylinder. They are designed to retain hydraulic fluids, exclude solid or liquid contaminants, and maintain hydraulic pressure. These tasks require a variety of different seal designs and performance-enhancing features. Seal material must conform to irregularities in metal surfaces to block fluid passage. To adjust to clearance gap size changes, the seal must expand or compress rapidly to follow dimensional variations. Finally, to resist being extruded into gaps, the seal must have sufficient modulus and hardness to withstand shear stress produced by system pressure.
Successful sealing involves containment of fluid within fluid power systems and components while excluding contaminants. The surfaces in contact with a seal determine what type to use. The surface can either be static or dynamic—in motion or without movement. Static seals are typically used when there is no relative motion between mating surfaces. Dynamic seals are the opposite. They are used when there is motion between surfaces. This can be either reciprocating or oscillating motions..
Hydraulic Piston Seals-SPG Piston seals Produced with a combination of special compound PTFE ring and 70 shore NBR Square-ring, our SPG designhas a wide application area. Being able to be usded safely at high linear velocity, SPG piston seals can also work in higher temperatures or different liquids by means of changing square-ring used as pressure ring.
