INA ball screw bearing use damage countermeasures

INA bearing structure design is fair and has the ability to improve the predecessor, will have a longer ball screw bearing life. Bearings are manufactured through multiple processing steps such as casting, heat treatment, turning, grinding and assembly. The fairness of each processing technology, the improvement of predecessors, and the inconsistency will also affect the life of the bearing. The heat treatment and grinding processes that affect the quality of the finished bearing often have a more direct relationship with the failure of the bearing. In recent years, research on the metamorphic layer of bearing working surface shows that the relationship between grinding process and bearing surface quality is closely related.

The metallurgical quality of INA bearing materials was once the main factor affecting the early failure of dynamic ball bearings. With the improvement of metallurgical technology (such as vacuum degassing of bearing steel), the quality of raw materials is improved. The proportion of raw material quality factors in bearing failure analysis has dropped significantly, but it is still one of the main factors affecting bearing failure. The proper selection of materials is still a factor that must be considered in bearing failure analysis.

The main task of INA bearing failure analysis is to find out the main factors causing bearing failure based on a large number of background materials, analysis data and failure modes, so as to propose improvement measures in a targeted manner, prolong the service life of bearings and avoid sudden occurrence of bearings. Early failure of sex.

1, bearing maintenance, overhaul, and abnormal handling

In order to maintain the original performance of the ball screw bearing in a good condition for as long as possible, it is necessary to maintain, repair, and prevent accidents, ensure the reliability of operation, and improve productivity and economy. Maintenance is best carried out on a regular basis in accordance with the operating standards for the mechanical operating conditions. The contents include monitoring of operating conditions, replenishment or replacement of lubricants, and inspections for periodic disassembly.https://www.supplyforever.com/
