Heat-treatment
Through quenching、deep cooling and tempering, reduced the surface decarburization of inner and outer wheel blank, enhanced the metallographic structure of metal, and increased the wear-resisting life of products.

Quality Materials
The automatic raceway superfine grinding equipment which is independently developed and manufactured by the company is suitable for the processing of special miniature bearings. It ensures the products have the effect of super-quiet when running.

Full-automatic assembly line
Independently developed and manufactured the automatic assembly、 adding ball、greasing and cap fitting equipment
has been independently designed and upgraded. After 5 generations, the production efficiency has been doubled.
Roughness Tester
The bearing is inspected (for roughness and waviness), and the contact state of the rolling elements is accurately simulated using morphological filtering technology to comprehensively evaluate the bearing's rotational accuracy and lifespan
