1. The installation process is not proper to form the deformation of the raceway surface; the work friction is hot,
2. The bearing and the shaft, the bearing and the bearing chamber cooperate too tightly or too loosely. Especially the over-tightening will make the bearing heat swell; the clearance is reduced. The 黾 ゲ ゲ ゲ 〠3, the machining accuracy of the other parts is not good. For example: the two ends of the frame Different axes of the mouth; the end cover is different from the bearing chamber; machining ellipse can cause the bearing to overheat.
4, the bearing itself is of poor quality; the gap is too large; the raceway is unclean; there is rust; the roll is not round, etc.
5, poor smooth; too much or too little smooth; grease is dirty.
