Based on advanced bearing technology, NiuShang tensioner bearings have been meeting the stringent requirements of Hyundai, Kia, Volkswagen and other automakers for many years. Our design philosophy is as follows. Optimum material selection for high temperature use Ideal sealing design to prevent grease leakage Low torque engineered to reduce excessive seal friction Grease selection for high temperature and prolonged use best clearance Tolerance control for correct alignment An automatic defect detector was installed in the process. Strict quality control enables us to aim for zero defects. We cover a wide range of car makes and models with over 500 part numbers.
