Definition -A Coupling Sleeve is a cylindrical component used in shaft couplings to connect two co-axial shafts. Its purpose is to transmit torque between the shafts while maintaining proper alignment and providing a secure mechanical connection. Coupling sleeves are commonly used in motors, pumps, compressors, and industrial power transmission systems.
