SKF cylindrical roller bearings Detailed bearing failure reasons:
The proper use of SKF cylindrical roller bearing is a long-term stability is not correct, however, the failure of the installation of cleaning the seals and grease may be a premature end to the life of cylindrical roller bearings, probably due to bearing failure can be divided into factors and internal factors.
Use factor refers to products manufactured after the installation and adjustment maintenance repairs, the products bear the load speed temperature vibration and lubrication seals are inseparable, so proper installation and regular testing can be reduced to reduce product the failure rate of regular maintenance to adjust abnormal immediately find out the reasons to adjust the recovery.
The internal factors refer to the structure of the product design and manufacturing process and quality of materials to determine the bearing quality of the three factors, SKF cylindrical roller sub-products used in bearing steel is processed through special heat treatment and cleaning degassing carburizing steel, steel failure The rate is the major internal factors to reduce the product life, design and manufacturing processes are unified machinery manufacturing, steel internal uncertainty causes a variety of . Metallurgical technology (such as advances in bearing steel vacuum degassing, etc.), raw material quality is improved. The proportion of raw material quality factors in the analysis of bearing failure has decreased significantly, but it is still one of the main factors bearing failure. The selection of the adequacy of the still bearing failure analysis must take into consideration.
The manufacture of bearings generally have to go through a multi-channel processing such as forging, heat treatment, turning, grinding and assembly. The rationality of the process, advanced, stability will also affect the bearing life. Which affect the quality of the finished bearing heat treatment and grinding process, and often have a more direct relationship with the bearing failure. In recent years, the grinding process and the quality of the bearing surface is closely related to the bearing surface deterioration layer.
