(EN) ROLLING BEARING
(FR) PALIER À ROULEMENT
(JA) 転がり軸受
Abstract
(EN) This rolling bearing is configured such that: every one of an inner ring, an outer ring and a rolling body is formed from a steel material; and (A) an Ag coating film is formed on the surface of the rolling body and a Cr coating film is formed on the raceway surface of at least one of the inner ring and the outer ring, or (B) a Cr coating film is formed on the surface of the rolling body and a Cr coating film is formed on the raceway surface of at least one of the inner ring and the outer ring.
(FR) L'invention concerne un palier à roulement conçu de telle sorte que : chacun parmi une bague interne, une bague externe et un corps de roulement est formée à partir d'un matériau en acier ; et (A) un film de revêtement d'Ag est formé sur la surface du corps de roulement et un film de revêtement de Cr est formé sur la surface de chemin de roulement de la bague interne et/ou de la bague externe, ou (B) un film de revêtement de Cr est formé sur la surface du corps de roulement et un film de revêtement de Cr est formé sur la surface de chemin de roulement de la bague interne et/ou de la bague externe.
(JA) 本発明の転がり軸受は、内輪、外輪及び転動体が何れも鋼鉄材料からなり、かつ、(A)転動体の表面にAg被膜、内輪及び外輪の少なくとも一方の軌道面にCr被膜、または(B)転動体の表面にCr被膜、内輪及び外輪の少なくとも一方の軌道面にCr被膜が形成されている。
