For the use of the bearings, must maintain regular, when we size precision, the bearing rotation accuracy, and internal clearance as well as the mating surfaces, the raceway surface, rolling surface, cages and seals, if abnormal phenomena, are the need for repair, or replacement. Do you want to replace the bearings, can be judged by the bearing or bearing are used in.
For mechanical equipment can be carried out and the normal operation of the work, we must use the bearing to judge, because the normal use of bearing damage will directly affect the mechanical equipment, below the bearing network to tell you whether you need better judgment of the bearings, can be analyzed by the following two points.
1, bearing parts of the fault and defect;
2, the raceway surface or rolling surface stripping.
