Abstract: front page image
(EN)Disclosed is a grease composition which contains a perfluoropolyether oil as a base oil while containing melamine cyanurate as a thickening agent in an amount of at least 10% by mass of the total mass of the grease composition. Also disclosed is a bearing in which such a grease composition is hermetically enclosed. Such a bearing in which the grease composition is hermetically enclosed has sufficiently long life even under high temperature conditions.
(FR)L'invention concerne une composition de graisse contenant une huile de perfluoropolyéther comme huile de base ainsi que du cyanurate de mélamine comme agent épaississant à une teneur d'au moins 10% en masse par rapport à la masse totale de la composition de graisse. L'invention concerne également un palier où une telle composition de graisse est hermétiquement enfermée. Un tel palier présente une durée de vie suffisamment longue même sous des conditions de hautes températures.
(JA) 基油としてパーフルオロポリエーテル油を含有し、増ちょう剤としてグリース組成物の全質量に対して少なくとも10質量%のメラミンシアヌレートを含有するグリース組成物;およびこれを封入した軸受を提供する。本発明のグリース組成物を封入した軸受は、高温下においても、充分満足出来る長寿命を得ることが出来る。
