JAMA now is focusing on production of chain sprocket. JAMA's bearing units series are created based on unremitting efforts. The product performs well in heat resistance. The materials used in it have a high coefficient of heat conductivity and a relatively low coefficient of linear expansion which make it not prone to fracture under high temperature. JAMA has a wealth of engineering experience with qualified professional and technical personnel.

Our business philosophy is to win the market through quality and service. All of our teams are working hard to create value for customers, no matter helping cut production costs or improving product quality. We hope to win their trust by doing these.
