(1) the roller bearing has higher load capacity than ball bearings.
(2) than the corresponding full roller bearings with a cage bearing can bear heavier load.
(3) the ball bearings are mostly used for medium or small load.
(4) NU, N type cylindrical roller bearings, needle roller bearings and CARB bearings can only bear pure radial load.
(5) thrust ball bearings and four point contact ball bearing is suitable for small or medium to pure axial load of bearing.
(6) can bear axial load in the middle of the high speed single, double row angle contact ball bearing, one-way bearings can bear radial load simultaneously acting, but usually only for two-way bearings subjected to pure axial load.
