Dvojni valjasti ležaji
Obstajata dve vrsti konstrukcij dvotračnih valjčnih ležajev: cilindrična notranja luknja in konična notranja luknja. Ta vrsta ležaja ima prednosti kompaktne strukture, visoke togosti, velike obremenitve in majhnih deformacij po nakladanju, itd. Razdeli se lahko v dve vrsti: NN serija in NNU serija. NN serije valjčni ležaj ima dvojno prirobnico na notranjem obroču, vendar na zunanjem obroču ni prirobnice. NNU tip ležaj ima dvojno prirobnico na zunanjem obroču, vendar brez prirobnice na notranjem obroču. Oba ležaja ne omejujeta relativnega aksialnega premika med gredjo in ohišjem in ju lahko uporabimo kot nenamenske ležaje.
