KMR dedicated into spherical and cylindrical roller bearing research and development with endless effort, KMR is the only state authorized E-design self-aligning spherical roller bearing R&D center in China, Set up mining machine bearing R&D center, super precision bearing technology laboratory, Provincial industrial design center; 

Innovation is the incentive, KMR is sanctioned by 21 patents, including, 9 national invention patents, and 12 new technology patents, which are the trailblazing technology in China.

We uphold “the technology can make greater bearing”, always invest the R&D continuously, endeavored to contribute to bearing improvement.

Material analysis technology: focus on bearing steel research and development by the professional engineers team with years’ experiences and commitment, design and develop the most suitable bearing steel for the KMR bearings.

Design technology: transmission dynamic analysis, connection deformation mathematical model, roller stress distribution analysis;

Friction lubrication technology: the friction analysis mathematical model, lubrication technology mathematical model,optimal lubrication thickness algorithm, optimal proportion between surface roughness and lube thickness,

Surface treatment: Nitriding, cementation, carbonitriding, sulfurizing, blacking, anticorrosion technology etc, this workmanship increase the surface lubrication efficiency significantly. 

As the prominent bearing leading manufacturer, KMR always stick to “strength in R&D” as our precepts, prioritized R&D, invested more than 10% net profit annually as the R&D expenses to keep up the international vanguard technology. This is the keynote why KMR leading the bearing manufacturing in China.

KMR cooperated with LUOYANG bearing R&D institution which is the only national integrated bearing R&D center in China to set up a state authorized bearing R&D center jointly.

In light of KMR expertise and reputation, nominated as the bearing quality standard regulation drafter, spearhead 5 Chinese bearing quality standard regulation.
