Seal Function & Motion
Dynamic Applications (Rotary Shaft Solutions)
These are used in dynamic applications, in which at least two hardware surfaces come in contact with one another. In dynamic applications, at least one surface is in motion relative to the other. A typical example is a hydraulic cylinder with shaft and bore. Further, there are two directions of motion in dynamic applications: reciprocating or linear motion, and rotary (including oscillating) motion. We offer mostly radial seals (rod seals and piston seals) in such applications. Occasionally, the application may be a combination of both static and dynamic. For these more complex cases, you can contact our team of experts.
The sealing solution is radial. Radial sealing has glands that compress seals in a radial direction. Male glands are machined in the shaft, whereas female glands are machined in the bore. Radial sealing is usually, but not always, dynamic.
We also offer rod seals and piston seals for these applications. Axial sealing has glands that compress seals parallel to the axis of the seal. Glands are machined on the face of the hardware. Axial sealing is usually, but not always, static. Omniseal® Solutions offers inside and outside face seals in such applications.
