<P>PROBLEM TO BE SOLVED: To provide a sliding member which can achieve low friction and long life so as to be used even under dry sliding condition by decreasing the friction coefficient μ from 0.35 to around 0.08-0.15 in the sliding section composed of O-ring with DLC film coated rubber, in an air cylinder equipped with the seal sliding member at all times. <P>SOLUTION: The air cylinder 1, as an example, has a piston 4 and a piston rod 3 as a pair inside a housing 2, and pressurized air is sent into an air room 7 alternately from air gateways 8, 9. To execute the function of cylinder 1, the O-ring 5 and O-ring 6 are pushingly inserted so as to prevent the air from leaking. In order to reduce friction coefficient of the O-rings 5, 6, electron beam is irradiated onto the film surface of DLC film coated rubber, and reduction of the friction coefficient is achieved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
