With increased needs for our bearing units, JAMA is expanding our factory scale. JAMA's chain sprocket is various in types and styles to meet the different needs of customers. Quality inspection for JAMAbearing wholesalers includes several parts: formaldehyde emission amount, harmful substances emitted from the adhesives, as well as the carcinogenic in the paint. This product is hypoallergenic. In the production process, any allergens caused by crude material ingredients, dyestuff or chemical additives are removed.

We make efforts to go green. By introducing some advanced manufacturing facilities, we reduce emission during our production and achieve energy conservation.
