All materials used to manufacture bearing units must meet safety, quality, and legal requirements in the industry. Most of manufacturers have an in-house QC team to assess and test the qualification of their raw materials before they actually apply them to the production of bearing units. Sometimes, they will also entrust the third party to further test and verify their raw materials or ask their raw materials suppliers to present necessary internationally-recognized certificates. The raw materials are the foundation of finished products, thus should be strictly selected.

Xiamen JAMA Bearing Co., Ltd is rapidly developing in the industry of manufacturing ball and roller bearing. Years of production and overseas marketing experience have created us a most respected corporate image of the manufacturing industry. The chain sprocket series is available in a wide range of types and specifications. The product has high CRI (color rendering index), which brings out the true colors of an object without appearing dinginess or inaccuracy. The mattress is the foundation for good rest. It is really comfortable that helps one feel relaxed and wake up feeling rejuvenated.
