NSK Bearings is famous because of the smaller, light weight, relative to withstand the load capacity, and broader applications. The needle bearing load is broadly divided into radial and axial load, the majority of the axial load capacity is relatively poor, in use due to the installation, use, maintenance and demolition would inevitably bearing failure. NSK Bearings failure for many reasons, all design and manufacturing process factors and bearing failure, analyzing them is not easy to judge. Collar more bearing company made a common cause of failure of NSK Bearings. Under normal circumstances, in general, from the use of factors and internal factors to consider and analyze.
Using the factor mainly refers to the installation and adjustment, maintenance, maintenance, repairs, etc. to meet the technical requirements. Installation conditions is one of the primary factors bearing often by the installation of inappropriate changes lead to the stress state of the entire bearing various parts, NSK Bearings in the normal state operation and early failure. The internal factors mainly refers to the structural design, manufacturing processes and quality of materials to determine the quality of several major factors of NSK Bearings. 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. NSK Bearings metallurgical quality of the materials once the impact Rolling early failure of the main factors. With the advances in metallurgical technology, raw material quality has been 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.
Bearing installation, use, maintenance, maintenance, technical requirements, bear on the operation of the bearing load, speed, operating temperature, vibration, noise, lubrication condition, grease quality and the surrounding media, atmosphere monitoring and inspection, abnormal immediately find reasons to be adjusted to return to normal. NSK Bearing failure analysis of the main tasks is based on a lot of background material, analysis of data and failure modes to identify the main factors that cause bearing failure, so that in a targeted manner of service, proposed improvements, extending bearing to avoid bearing the occurrence of sudden of early failure.
