Abstract

a. Secteur technique : Roulement pour montages de précision. b. Caractéristique technique principale : La bague intérieure du roulement est isolée thermiquement de l'arbre support et le diamètre des corps roulants est très inférieur au diamètre des corps roulants d'un roulement traditionnel de dimensions extérieures équivalentes, alors que leur nombre est plus élevé dans la même proportion, permettant d'obtenir une raideur plus grande et une consommation d'énergie plus faible. c. Application principale: Roulement support d'une broche de machine-outil.
