Improving performance through a commitment to quality.



YEXU has developed manufacturing equipment for in-house use that makes it possible to consistently select and control bearing tolerances that far exceed the specified requirements of the original electric motor manufacturer.  This results in measurements of micron (.001 of 1 mm) and sub-micron levels and manufacturing tolerances that use only a fraction of the allowable range.  Furthermore, this manufacturing equipment employs technology that insures this extremely high degree of tolerance, clearance and dimensional consistency is maintained from lot to lot, on a day in and day out basis.  As technology advances, YEXU continually upgrades the equipment to tighten and redefine internal production standards for Electric Motor Quality to levels that other manufacturers find unattainable.  EVERY ball bearing manufactured by YEXU must meet these standards for Electric Motor Quality which can actually improve the performance of your equipment. Some of the advantages of NYEXU include:


Lower bearing noise levels

Higher levels of dependability

Better running accuracy

More consistent fitting practices

Better machine parts positioning

Lower heat generation



Statistical Process Control, selected tolerances, and absolute manufacturing repeatability- what do these mean, and what do they have to do with YEXU Electric Motor Quality? These are the principles behind every YEXU bearing produced, assuring that rigid, specific production standards are maintained.


Before component parts feed into production lines, as well as after each stage of manufacturing operation and assembly process, there is an automatic quality check on 100% of the parts.  If parts fail to meet the high specifications, the automated production line shuts itself down for immediate attention.  This sophisticated process allows YEXU to set and maintain our own high standard for “zero defects.”
