Abstract:
A rolling apparatus comprising:a movable member which can undergo rotary or linear motion, a support member which carries the movable member, rolling elements which are interposed between the movable member and the support member and which roll with the movement of the movable member, and a lubricant composition which is disposed between the movable member on which the rolling elements roll and the support member, wherein the lubricant composition is a mixture of: (1) a thickening agent which is a fluoro-mica-based lamellar mineral particle containing at least one of a lithium ion and a sodium ion as an interlaminar ion or a mixture of said lamellar mineral particle and a solid fluoropolymer particle, and (2) a base oil comprising a liquid fluorinated polymer oil having a perfluoropolyether skeleton and no polar group, and an oily compound having a perfluoropolyether skeleton as a main chain and a polar group at either or both ends of the main chain and having a molecular weight of not more than 10,000 in an amount of from 0.5 to 10% by weight based on the lubricant composition.
