Title: Thrust bearing
Inventor: TACHIKI TAKESHI
IPC: F16C33/20
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To restrain an increase in weight and an increase in manufacturing cost, and enhance slidingly movable performance and durability by forming a thrust bearing of a polyether etherketone (PEEK) material. SOLUTION: A PEEK material is lower and softer in hardness than stainless steel and iron or the like being metal. Therefore, when the PEEK material is used in a thrust bearing 12, even if a metallic rotary shaft 1 slidingly moves, abrasion is not caused. The PEEK material is lower in hardness than metal such as stainless steel and iron, but is higher and harder in hardness than, for example, PSS and nylon. Therefore, when the PEEK material is used in the thrust bearing 12, even if the metallic rotary shaft 1 slidingly moves, a recess is not generated. Therefore, when the thrust bearing 12 is formed of the PEEK material, the thrust beating 12 becomes excellent in durability, and the service life can be lengthened.
