Belonging to automotive bearing, automobile wheel hub bearings adopt DAC series, which are also known as the double semi-inner ring double row angular contact ball bearings. It is an important product of our automotive bearings. Different from other automotive bearing, its special double semi-inner ring angular contact structure enables the bearing can bear maximum installation steel ball. Additionally, the interior 35°~40°contact angular design can greatly improve the capability of the bearing as well as extend its life span. Especially for the seal structure of the bearing, the engineer technical department of our company has designed and developed several combination seals by integrating various set of automobiles models with the working state of the bearing, which is proved by bench simulation test that it can effectively guarantee either static or dynamic seal of the bearing.
