The so-called NTN bearing presents a burn injury condition: the NTN bearing's race wheel, roll body and the support frame are heated rapidly during rotation until discoloration, softening, welding and damage. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Secondly, it may be excessive load (pre-pressure is too large). The rotation speed is too large. The clearance is too small. There is water or other foreign matter intrusion. If the above two conditions are not the case, the accuracy of the shaft and bearing housing is poor, and the shaft is Deflection is big. See here; I think we all want to know the way to deal with it; first; to study smoothing agent and smooth method; to select the bearing smoothing agent; and its dosage; and to correct the selection of bearings. Discussion cooperation, NTN Bearing clearance and preload; and improve the sealing equipment. Look at the accuracy of the shaft and bearing housing. Of course; if you have a professor around you; let him operate the best you learn!
