Abstract

Ein aus Lastrollen (6) und Trennrollen (7) bestehendes Wälzlager (1) zeichnet sich dadurch aus, dass die innerhalb des Teilkreises (TK) der Lastrollen (6) angeordneten Trennrollen (7) eine in radialer Richtung nach außen führende Bewegung (TM) ausführen können. Dadurch wird der Reibungskontakt der Trennrollen (7) mit der Innenlaufbahn (4) vermieden.
