Abstract

La présente invention concerne un roulement à bague élastique, et plus particulièrement, un roulement à bague élastique formé en insérant une bague élastique dans un roulement utilisé dans divers appareils ou véhicules industriels de façon à disperser la charge appliquée au roulement conformément à la rotation, ce qui diminue le bruit et les vibrations de conduite, et améliore la longévité. Le roulement à bague élastique comprend une roue interne, une roue externe, et un élément de roulement inséré entre la roue interne et la roue externe. Une bague élastique de roue externe est disposée entre la roue externe et l'élément de roulement.
