Lubricant supply member and the rolling bearing to provide the lubricant supply member, the linear guides and ball screw

摘要

PROBLEM TO BE SOLVED: To provide a lubricant-supplying material capable of being used at a high temperature such as 100-120 deg.C, also excellent in mechanical strength and holding a lubricant containing a highly polar lubricating oil such as an ester oil, a polyphenylether oil, etc., stably. SOLUTION: This lubricant-supplying material is provided by solidifying a polyester elastomer consisting of a hard component consisting of a first polyester with a soft component consisting of a second polyester or a polyether in a state of containing a mixture of a first lubricating oil having a highly compatible with the polyester component or a grease using the first lubricating oil as the base oil with a second lubricating oil having low compatibility with the polyester elastomer or a grease using the second lubricating oil and containing 3-25 wt.% second lubricating oil or its grease based on the total amount, and is characterized by oozing the first and second lubricating oil from its surface.
