Cushion sleeves are used in pneumatic cylinders to avoid impact force arising at the end stroke part between moving piston and cylinder cover. In this study low kinds of cushion sleeves are designed, manufactured and attached to the pneumatic cylinder to be experimented. The effects of cushion sleeves on cushion characteristics are investigated. e results are as follows; the pressure variation of cushion room with orifices are inspected to be smaller than that of cushion room without orifices. So sleeves with orifices are expected as protecting from impact and vibration of pneumatic cylinder. The object of this study is to provide data on the charactristics of pneumatic cushion sleeve in case of being used in industry.
