          Quality guarantee

           

          From raw material to finish products,every process is carried out according to strict standards and products are traceable relying on process tracking card so that all of them meet the international or national standards. 

          Technology & service

           

          We provide our clients with a complete set of product solution which is our competitive capacity.

           

          Taking into account of such factors of bearing as speed, life,accuracy and rigidity,our engineers offer bearing design,life calculation,product updating and application maintenance surport.  

           

          The fatigue life of bearings is greatly improved by using high-purity bearing steel to manufacture the inner and outer rings with special heat treatment and cold treatment processes, as well as special raceways with higher precision.
