Chain Couplings

Chain couplings are mechanical devices that transmit torque by meshing a roller chain with two sprockets mounted on the shaft ends. The assembly typically includes two sprockets and a double-row roller chain that links the driving and driven shafts. Chain couplings are compact, easy to install, and commonly used in low-speed, medium-torque industrial applications.

Chain couplings offer good compensation for axial, radial, and angular misalignment, allowing for flexibility during installation. The chain’s engagement also provides some shock absorption, which is beneficial in applications with variable loads. These couplings are widely used in conveyors, hoists, metallurgical equipment, and mining machinery. Optional protective covers can be added to enhance safety and extend the service life in demanding environments.
