Abstract

Ein Käfig eines Zylinderrollenlagers weist einen ringförmigen Abschnitt auf, mehrere Pfeiler, die sich einstückig und durchgehend von der Innenfläche des ringförmigen Abschnitts axial erstrecken, und mehrere Taschen, die zwischen den Seitenflächen in Innenumfangsrichtung von benachbarten Pfeilern ausgebildet sind und die Zylinderrollen frei drehbar halten. Die Seitenflächen in Umfangsrichtung der Pfeiler enthalten eine Kreisbogenfläche, die sowohl in Richtung des Innendurchmessers als auch in Richtung des Außendurchmessers, ausgehend von dem Wälzkreisdurchmesser, ausgebildet ist, der durch die Taschenmitte der Tasche läuft, und einen Abrollabschnitt (Schmiermittelspeicher), der am inneren Umfangsabschnitt des Spitzenendes vorgesehen ist.
