[0002] Rubber ball joints, as a high-performance elastic connector, are widely used in mechanical transmission systems. They use the good elasticity and shock absorption properties of rubber materials to achieve flexible connection and angle adjustment between connecting parts. Rubber ball joints can not only effectively absorb vibration and impact, protect the system from damage, but also maintain stable transmission performance under complex working conditions. Its unique spherical structure makes installation and alignment easier and adapts to a variety of installation angles and space restrictions. In addition, rubber ball joints also have good corrosion resistance, wear resistance and sealing, ensuring long-term reliable operation. In the fields of automobiles, ships, aerospace and industrial machinery, rubber ball joints play an irreplaceable role and are important components in modern transmission systems.
