Cylindrical roller bearings Ii can bear more radial load comparing with same size deep groove ball bearings, and it also has high processing requirement of shell hole or the precise inclination between inner and outer axis ring (2 ¡ã -4 ¡ã) it can be also applied in main parts of main machine to bear axial load simultaneously running with other bearings. If no other bearings, it will reduce the operation life.
