fatigue will occur as soon as possible

Reasonable assembly premature failure of the Slewing bearing service life is also extremely important. Machinery and equipment which use the same types of bearings, domestic and imported there are obvious differences, this is mainly because the material and machining accuracy is also equipped with the irrational can not shirk responsibility. Assembly method is correct or not directly related to the ability to ensure proper clearance, if improper assembly and disassembly, ranging from the formation of indentations in the raceway, weight will cause the bearing scrap. If the gap is too small, the additional torque bearings will increase. Bearing centerline and the bearing bore centerline between the angular displacement increases, will the working status of bearing deterioration, these must be avoided.
 When the backing bearingsis overloaded, fatigue will occur as soon as possible. If the reason for damage to the overload, then try to use the installation and design of the bearing load capacity, and according to the design requirements of timely maintenance and updates. Pitting is the most typical form of bearing failure, mainly because of the bearing frequent impacts during transportation and incorrect assembly, make raceway indentation. When the raceway after indentation. The rotating roller, each indentation is produced after a first impact, on a rolling indentation effect, when the load increases, the greater the pressure roller in the cycle of movement which, at the indentation will produce flakes peeling, and to increase the vibration, noise increases.
