Abstract

PURPOSE:To reduce operation torque and to reduce a wear amount of a retainer itself, by a method wherein ceramic fiber and wollastnite are contained in ethylene tetrafluoride resin to use it as the material of a retainer for a bearing. CONSTITUTION:Ethylene tetrafluoride resin is a single polymer of tetrafluoroethylene. Wollastnite is also called as calcium silicate and natural or artificial chainform silicate CaSiO3. Wollastnite has preferably an average fibre length of approximate 10-100mum, and an aspect ratio of approximate 10 or more. In ceramic fiber consisting mainly of silicon dioxide and aluminum oxide, an occupation ratio of the two components is preferably approximate 90wt.% or more and an average fibre length is preferably approximate 10-300mum. An amount of both or the one of wollastnite and ceramic fibre being mixed in tetrafluoride ethylene resin is preferably approximate 5-90wt.pts. based on 100wt.pts. tetrafluoride ethylene resin. The raw materials are mixed and molded to manufacture a retainer for holding a roller bearing.
