Abstract

Die Erfindung betrifft ein Distanzstück (1) für ein Kreuzrollenlager, das zwei im Wesentlichen rechteckige, gegenüberliegende und jeweils benachbarten Zylinderrollen zugewandte Deckflächen (8) aufweist, wobei sich auf jeder Deckfläche ein Kontaktbereich befindet, der jeweils durch alle im zusammengebauten Zustand des Kreuzrollenlagers möglichen Kontakte zwischen dem Distanzstück und der benachbarten Zylinderrolle gebildet wird und der eine Profilierung in Form von mindestens einer Nut (5) aufweist. Um ein einfach und kostengünstig zu fertigendes Distanzstück bereitzustellen, dass ohne Verschlechterungen bei der Führung der Zylinderrollen eine spürbar bessere Benetzung der Zylinderrollen ermöglicht, ist eine Längsrichtung der mindestens einen Nut gegenüber einer Rotationsachse der benachbarten Zylinderrolle geneigt.
