In order to determine the bearing removed can re-use, to check on the accuracy of rotation accuracy, internal clearance, and the mating surfaces, raceway, wind power bearing cage and sealing ring.
About the examination results, can be judged by the bearing or bearing are used in.
Criteria based on the mechanical properties and the important degree and the inspection cycle and different. If the following injury, bearings shall not be re used, must be replaced.
1) bearing parts of the fault and defect.
2) the raceway surface Angular contact ball bearings rolling surface stripping.Show cross spiral line traces the emergence of such traces is mainly due to the bus straight wheel of existence, bump phenomenon, when in grinding, the grinding wheel and the workpiece is only part of the contact, when the workpiece or the grinding wheel reciprocating motion after several times, cross spiral line and the naked eye reproduced on the workpiece performance will be taper roller bearing observed. The helix pitch and workpiece speed, rotational speed of workpiece size, but also with the wheel axis and the guide rail is not parallel to the working table.
