(2) The rolling bearing grease is too small, too much or has iron scraps and other impurities. The capacity of the bearing grease should not exceed 70% of the total volume; those with impurities should be replaced.
(3) The shaft and the bearing cooperation are too tight or too loose. When overtightening, it should be ground from the head; when it is too loose, the shaft should be set.
(4) The bearing and the end cap cooperate too tightly or too loosely. The bearing chamber is machined when it is too tight; when it is too loose, the steel sleeve is set in the end cover.
(5) Poor installation of the two caps or bearing caps of the motor. Install or flatten the end caps or bearing caps; tighten the screws.
(6) The belt is too tight or the coupling is not properly installed. Adjust the belt tension; proofread the coupling.
(7) The sliding bearing lubricant is too little, there is impurity or the oil ring is stuck. It should be like refueling or replacing new oil; repair or replace the oil ring.
