Specifications for effective sealing systems

Designing hydraulic rod and piston sealing systems requires careful attention to the dynamic seal interaction and the principles of tribology to ensure long service life, proper seal function, minimal wear, low friction and smooth operation. Tribology is the study of the design, friction, wear and lubrication of interacting surfaces in relative motion. The most important considerations for tribological properties of a dynamic sealing system are:
  • the seal material
  • the seal profile design
  • the counter-surface material and finish properties
  • the hydraulic fluid, which is the lubrication for the dynamic sealing surfaces
For information about seal profile design, refer to the relevant product section.
