Main reasons of fracture failure of SKF bearings are two factors deficiency and overload. When plus loads more than material intensity caused part overload fracture fracture is called the limit. Overload causes the main host of sudden failure or improper installation. Bearing parts of micro-cracks, shrinkage, bubble, a large, foreign bodies, organizations and local overheating burn in shock overload or severe vibration when the defect will cause fracture at the defects, defects called fracture. It should be noted that SKF in bearings manufacture, re-inspection of raw materials into the plant, forging and heat treatment quality control, process control through instruments and correct analysis of the flaws exist, still controls must be strengthened in the future. In General, however, usually bearing failure occurred mostly overload failure.
SKF bearing failure analysis of main tasks is based on the large amount of background material, analysis of data and failure mode, identify the main factors causing bearing failure, so targeted for improvement measures, extending the service period of SKF bearings, avoid unexpected early bearing failure.
SKF bearing in running process in the, sometimes bearing surface Zhijian will squeeze into external hard particle or hard mass foreign body or metal surface of mill chip, this will is bearing caused plow ditch shaped of abrasions, these hard foreign body through lubrication media entered SKF bearing internal, as SKF bearing of constantly running, local friction health hot, easy caused friction surface local deformation and friction micro welding collection phenomenon, even may appears local melted of situation, last caused occlusal phenomenon.
SKF bearing breaking cause of defects and overload two factors when plus loads more than material intensity limit caused part overload fracture fracture is called, bearing overheating can also occur in the course of running organizations and local defects such as burns, defects caused by faults. In general we can instrument to check what kind of fracture, in most cases, fracture mostly caused by overloading of SKF bearing failure.
