A 2 giri di rulli cilindrici Alta precisione

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 avereforo cilindrico o conico. Per la lubrificazione hanno una scanalatura circolare e tre o sei fori sull’anello esterno. Suffissi:

SP super precisione
K Foro conico, conicità 1:12
W33 Scanalatura circonferenziale e tre fori di lubrificazione sull’anello esterno
TN Gabbia stampata ad iniezione, a scatto, in poliammide 6.6 rinforzata con fibre di vetro
