ZHEJIANG TESTING & INSPECTION INSTITUTE FOR MECHANICAL AND ELECTRICAL PRODUCTS QUALITY was set up in 2013. It was constructed according to the domestic first-class standard. It consists of finished bearing test room, bearing parts testing room, bearing performance testing room and metallic material test room.

Testing abilities:  
1. Finished bearing dimension tolerance, rotation accuracy,vibration,life time, sealability  
2. Bearing parts dimension accuracy, heat treatment quality, crush load 
3. Metallic material hardness,mechanical performance, microstructure,chemical composition and salt spray test

HANGZHOU BEARING TEST & RESEARCH CENTER CO.,LTD. was established in 1980.It covers a testing area of 2000 square meters and has 150 sets testing machines. It engages in bearing dynamic performance and fatigue life research. It is regarded as authority because of their solid technical foundation. They developed BVT series bearing vibration tester and ABLT series accelerated bearing life tester. They also supply technical training and technical consultation.

And we also inspect product quality by ourselves factories, Zhenjiang Kejia and Changzhou Kejia all purchased all kinds of inspect equipment for test bearing quality for keep long and stable quality, and we also cooperate a friend factory in Shanghai for inspect many other suppliers’ bearing quality before ship the goods.

Above Hangzhou, Zhenjiang, Changzhou, Shanghai is Kejia’s four base of quality inspect, all these make all goods quality under strictly control.
