Abstract
An inner ring 2, an outer ring 1 and a cage 4 are made of a resin composition comprising a melt-moldable fluoro-resin as a main ingredient, which can provide a rolling bearing capable of maintaining lubricity for a long period of time even when it is used in a corrosive aqueous solution or under a circumstance where mists or droplets of a corrosive solution are present.
Claims7
A rolling bearing comprising at least an inner ring, an outer ring and rolling elements made of a corrosion resistant material, characterized in that:
- at least one of the inner ring and the outer ring is made of any one of a melt moldable fluoro-resin, a resin composition comprising the melt moldable fluoro-resin as a main ingredient or a resin composition comprising a melt moldable heat resistant resin incorporated with a fibrous filler and/or a solid lubricant.
A rolling bearing comprising at least an inner ring, an outer ring and rolling elements made of a corrosion resistant material, characterized in that:
- at least one of the inner ring and the outer ring comprises a resin composition in which a liquid crystal polymer is added by at a ratio of 50% by weight or less to a melt-moldable fluoro-resin or a melt-moldable heat resistant resin.
