Beschreibung
Zusammenfassung:The tolerance ring (20) has a resilient tolerance ring base (21) of polymeric material. The tolerance ring base is provided partially with a nanocrystalline metallic coating (22). The coating is formed of particles with average grain size of less than or equal to 500 nm. The coating has layer thickness in specific range. The coating is made of metal or metal alloy comprising element selected from the group consisting of iron, cobalt, nickel, copper, silver, gold and titanium. The coating is formed of iron alloy and/or nickel alloy. An independent claim is included for a rolling bearing. Die Erfindung betrifft einen Toleranzring (20) zum Toleranzausgleich zwischen einer Welle (1), insbesondere einer Lenkwelle, und einem Innenring (10) eines Wälzlagers, welcher einen elastisch federnden Toleranzring-Grundkörper (21) aus einem polymeren Material aufweist, der (21) zumindest abschnittsweise mit einer nanokristallinen, metallischen Beschichtung (22) versehen ist. Darüber hinaus betrifft die Erfindung ein mit einem derartigen Toleranzring (20) ausgestattetes Wälzlager.
