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.
① shows the feature of KOBA' s Multiple orifice that keeps stopping shock energy slowly & smoothly providing the constant power of resistance.
② 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.
③ 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.
