Koganei / Linear orifice shock absorber

Koganei's original shock absorber was developed by air cylinder engineers. The linear orifice mechanism, in which the orifice changes linearly, achieves smooth shock absorbing characteristics and long life. The inner tube is not required and the inner diameter of the body can be enlarged, resulting in high performance and soft shock absorption despite its compact size.
