SKF Expert System Helps Reduce Bearing Failures

Writer: Eric Bearing Limited

In 1907, the Swedish engineer Sven Winquist invented the spherical ball bearing in his hometown of Gothenburg, and the SKF Group was born. SKF Bearing Company is a world leader in the bearing manufacturing industry. The group is headquartered in Gothenburg, Sweden. SKF bearing business spreads all over the world. 

SKF Bearing Company provides standard products with more than 20,000 kinds of bearings. The small ones are like miniature bearings weighing only 0.003 grams, up to giant bearings weighing 34 tons each. Varieties include deep groove ball bearings, cylindrical roller bearings, spherical roller bearings, tapered roller bearings, angular contact ball bearings, needle roller bearings and many other types. In addition, SKF also provides a series of shafts

Undertake maintenance tools, grease and bearing monitoring instruments, so as to enable bearing users to obtain higher benefits and achieve worry-free operation.  SKF 7328 BCBM bearings online , pls click here :

 "The SKF expert system uses the data provided by the customer to carry out probabilistic analysis, thereby linking these data with the basic data of the database. The system summarizes a series of causes of bearing failure and ranks them according to probability." Recently, SKF successfully developed “Expert System” is used to analyze the causes of bearing failures, so as to help customers avoid recurring

Bearing failure problem. Although this system is not the first in the bearing field, it makes up for the deficiencies of previous bearing fault detection systems.The previous system is often a decision-making chart structure, and the possible cause of the bearing failure can be inferred from the symptoms. The system works in another way-from the cause to the symptoms of bearing failure.   

The core of the system

The core is a series of related professional knowledge from the basic principles of rolling bearings to practical engineering and application results. It has four categories, namely:   
1. Conditions (speed, bearing type, load, temperature, etc.)   
2. Internal mechanical devices (such as sliding contacts and the destruction of the lubricating film)   
3. Failure methods (including surface initiation Fatigue cracks and friction Corrosion)   
4. Symptoms (such as embroidering, spalling, and fading)    

The SKF expert system uses the data provided by the customer to carry out probabilistic analysis and links these data with the basic data of the database.
