Definition -A Muff Coupling Sleeve is a cylindrical hollow sleeve used in a muff (sleeve) coupling to join two co-axial shafts. Its purpose is to transmit torque from one shaft to the other while maintaining alignment and providing a rigid, simple connection. Muff coupling sleeves are commonly used in motors, pumps, compressors, and general industrial power transmission systems.
