JAMA is fully dedicated to the R&D and production of car bearing. As one of JAMA's multiple product series, oil seal series enjoy a relatively high recognition in the market. The product is not prone to fracture. Its sturdy construction can withstand extreme cold and hot temperatures without getting deformed. High quality service going with elaborate ball & roller bearings can keep JAMAmore competitive.

We minimize the negative impact of our production activities and promote both recovery and environmental-protection projects. We are developing new technologies in order to avoid unnecessary resource consumption.
