Product Description

The ball joint is a rubber elastic connecting element installed on the primary and secondary drawbars, booms, jibs, motor suspensions, hydraulic vibration damping and other systems of various vehicle bogies, with flexible connection and elastic positioning. , its stiffness range is relatively flexible, and ideal radial, axial, deflection and torsional stiffness can be achieved, thereby ensuring the smooth operation of the vehicle system and improving the safety and comfort of the vehicle. Our company has cooperated with domestic and foreign companies to produce more than 100 types of ball joints. And can customize various functional ball joints according to customer needs.
