Description Of Hydraulic Cylinder Seals

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 Rod Seals-single acting rod seal

K33 is a single acting rod seal with an extra lip designed for a wide range of hydraulic applications. K33 lip design offers an optimum oil film while the secondary lip provides additional wiping performance and system safety.


 Advantages

 • Secondary sealing lip provides extra protection against the ingress of dirt particles.

 • Very good sealing thanks to the cut processed lip structure

 • High wear resistance 

• Easy installation into closed grooves 

• Wide range of standard products

 • Simple groove design 

Area of Application

 • Presses • Construction machinery • Cranes • Injection moulding machines • Mobile machinery • Industrial cylinders
