KMS series

KMS Series are small and self-adjusting type.
They keep absorbing mechanical shock slowly & smoothly due to their special designed multi orifice.

If a bumper head type is used, it prevents the bottoming phenomenon that may be caused at the end of a cycle. Therefore, stop collar isn't required.

Self-Adjusting damping force

shows the feature of KOBA' s Multiple orifice that keeps stopping shock energy slowly & smoothly providing the constant power of resistance.
shows that it decreases gradually with providing big power of resistance at the first stage and occurs when load is light and velocity is very fast.
shows that it fails to slow down the power of resistance at the early stage and occurs when a power of resistance rises at the end stage, speed is getting slower and weight is big.
