O Ring Mechanical Seals WM103B

One of the key strengths of an O Ring Mechanical Seals WM103B is that after the parts it joins are disconnected and the compression forces acting on it are removed, it will return to its original shape. Over time, repeating this process will start to have an effect on the resilience and uniformity of the materials and the torus shape of the seal, and ultimately the o-ring will need swapping out for a new one if the seal is to remain tight.

What is the difference between static and dynamic o ring mechanical seals?

Static and dynamic o ring mechanical seals design differs in a few key ways. A static O-ring is any o-ring designed to contact with two or more surfaces that do not move relative to one another, whereas a dynamic O-ring is one that helps form a seal between moving parts.

On the whole, static o ring mechanical seals are created from less robust and hard-wearing materials than their dynamic equivalents. It’s also important that the components being joined together in a dynamic environment are carefully designed and finished, such that they will not abrade, shear, and eventually destroy the O-ring positioned between them. This is less of a concern for o ring mechanical seals used in static applications, as the only stress force they’ll be under is usually compression (to which they tend to be fairly resilient).

While all o ring mechanical seals require some degree of lubrication in order to perform to optimal levels, dynamic o-rings require heavier and more frequent lubrication (as well as more regular checking, maintenance, and replacement) than static versions. Different types of dynamic movements - for example, rotary, reciprocating, and oscillating - demand that o ring mechanical seals be manufactured with different material qualities to perform to the optimal level.
