cylindrical roller bearing
Depending on the existence of ribs on their rings,Cylindrical Roller Bearings are classified into following types.Type NU.N,NNU,and NN are suitable as free-end bearings.Types NJ and NF can sustain limited axial loads in one direction.Type NH and NUP can be used as fixed-end bearings.
NH-type cylindrical roller bearings consist of the NJ-Type cylindrical roller bearings and HJ-type L-shaped thrust ciollars.
