Star Coupling is a high-performance mechanical coupling designed with star-shaped elastomer elements and has excellent buffering and shock absorption capabilities. It can effectively compensate for radial, angular and axial offsets between shafts to ensure smooth and stable power transmission. The coupling has a compact structure and is easy to install and maintain. It is widely used in motors, pumps, fans and various mechanical equipment to improve equipment operating efficiency and service life.
