More Information
Summary:An air cylinder that can prevent foreign substances from intruding inside in an environment where fine foreign substances such as dust are scattered. The air cylinder includes, in a through hole of a rod cover, an annular lubricator impregnated with a lubricant so as to supply the lubricant to the rod and a liquid-absorptive annular dust wiper not containing a lubricant and provided for preventing fine foreign substances such as powder stuck to the rod from intruding inside. The lubricator and the dust wiper are disposed air-tightly and slidably in contact with the rod, and the dust wiper is located closer to a leading end of the rod than the lubricator.
