How important are bearings? Speaking of rolling bearings alone, you can look at the failure data of these machines:

30% of the faults of rotating machinery are caused by rolling bearings;

40% of the faults of induction motors are caused by rolling bearings;

20 percent of gearbox faults are caused by rolling bearings;

Each year 40% of rolling bearings used by locomotives in China have to be unloaded for inspection, 33% of which need to be replaced;

After bearing condition monitoring and diagnosis, the accident rate is reduced by 75%, and the maintenance cost is reduced by 25%-50%!

Rolling bearings support and guide machine rotation or swing elements — such as shafts, axles, or wheels — with minimal friction and transfer loads between machine parts.
