I cuscinetti a due corone di rulli cilindrici di solito hanno un piccolo ingombro radiale, una forte capacità di carico e una elevata rigidità strutturale. Prefissi: NNU rulli sono guidati fra gli orletti dell’anello esterno, con NN fra gli orletti dell’anello interno. L’altro anello è privo di orletti e sono permessi moderati spostamenti assiali dell’albero rispetto alla sede. Sono smontabili, i rulli e la gabbia possono essere sfilati dall’ anello privo di orletti e assemblati separatamente. Il loro montaggio è quindi semplice. Possono avere foro cilindrico o conico. Per la lubrificazione hanno una scanalatura circolare e tre o sei fori sull’anello esterno. Suffissi:
M Gabbia massiccia in ottone in due parti
