Hydraulic Seals

Anywhere & Everywhere Fluid Power Is Used To Create Motion.

Hydraulic cylinders perform work transmitting power into motion in a bevy of different situations, applications, and markets. They provide high force in a small package and are working to create motion almost everywhere. The design, size, seal package, and component materials vary according to the pressure, temperature, cycle requirements, and multiple other requirements of the application.

Hydraulic seals are crucial to the safety, performance, and efficiency of a functioning cylinder. They can prevent internal and external leakage or bypass of the hydraulic fluid, keep outside contamination particles and debris from entering the cylinder, perform in static or dynamic applications, and even eliminate any metal-to-metal contact of different cylinder components.

To maximize performance and avoid failures, hydraulic seals must be selected according to your application’s needs. Some of the variables to consider are:

  • Compatibility to water, various oils, or exposure to chemicals and cleaning agents
  • Ability to withstand extremely high pressure, pressure spikes or rapid changes in direction of pressure
  • High and/or low temperature either environmentally or created within the system
  • High speed or dithering applications
  • Sound generation – reduction in “howling”
  • Side loaded applications
  • Cushion effects at either end of stroke
  • Work environment contamination such as abrasive particles, dirt/mud, ice, etc. that can be in contact with the exposed cylinder rod

Hydraulic seals are offered in a very wide variety of profiles and materials to meet the needs of this extremely demanding market. It is of the utmost importance, however, that the right combination is used. Each seal is equally as important as the weakest link will cause the chain to fail. The exact material, size, and profile, working in unison must be designed to create the optimal efficiency of the hydraulic cylinder.
