Spring energy storage seals can be used in a variety of applications, such as
dynamic and static or internal and external pressure, using v-shaped or H-shaped
spring form and seal lip design, thus showing different sealing forces and compressible deformation (as shown). The size of the spring force will affect the sealing performance, friction and wear behavior of the spring energy storage seal; The
compressible stroke determines the compensation ability of the spring energy
storage seal for the wear of the seal lip and the tolerance variation of the size of the
seal groove.
