ntn bearings with metal bearing difference
1, plastic bearings and the phenomenon does not occur in rust resistant and rust metal bearing can not be used for chemical liquid;
2, plastic bearings are lubricated materials overall, long life; while FAG bearings lubricated metal sliding surface layer is only 0.003mm of PTFE, a thin layer of friction when it finished pluralism and the end of life;3, plastic ntn Bearing manufacturing cost is lower than the metal;
