<p><P>PROBLEM TO BE SOLVED: To provide a lubricant with sufficient oil film strength in which oil film cutting is suppressed from being generated at a slide part by sufficiently flowing out it from a vacancy and a bushing has sufficient abrasion-resistance life when the bushing is impregnated with the lubricant, and an oil non-feeding chain in which a bushing is impregnated with the lubricant. <P>SOLUTION: In the oil non-feeding chain 1, a pair of outer plates 4, 4 connected by pins 5, 5 and a pair of inner plates 2, 2 for inter fitting adjacent pins 5, 5 of the adjacent outer plates 4, 4 and connected by the oil-containing bushings 3, 3 are alternately connected. In the oil-containing bushing 3, the bushing is impregnated with a lubricant having a dynamic viscosity of ISO-VG grade 46-460, the number of an effluent component measured by the GPC method of 1, the number average molecular weight of 800-2,300 and a ratio of a mass average molecular weight and the number average molecular weight of 1.0-1.2. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
