C85 stainless steel micro pneumatic cylinder increase in the use of stainless steel cylinder, the product of its main features is the relatively small volume and quality of comparatively light, and in the process of using equipment power consumption is low, so in some medicine and has been widely used in electronic components industry, when processing due to volume is small, so the size of the products is limited by a certain time, light-duty and miniaturization of the products is now development goals.
