Functionality is paramount in the design of a coupling sleevecoupling sleeve. It must be able to handle not only the torque being transmitted but also any axial or radial loads that may occur. Some designs include rubber or metal elements to absorb shock and reduce noise, further enhancing the performance of the coupling system. Additionally, the sleeve should allow for easy installation and removal to facilitate maintenance and replacement when necessary.
