Abstract

L'invention concerne un roulement à rouleaux du type comportant une bague intérieure, une bague extérieure et des rouleaux. Selon l'invention, les bagues et les rouleaux sont réalisés en un matériau ayant une dureté d'au moins environ 65 Rockwell C, c'est-à-dire d'au moins environ 233 kg/mm**2. Un tel roulement peut fonctionner sans graissage, dans une atmosphère chargée en poussières hautement abrasives.
