Couplings are designed for reliable torque transmission in conveyors, crushers, reducers, motors, and other drive systems used in bulk material handling and general industrial applications. Yuxin Machinery offers variations of couplings such as jaw couplings, grid couplings, and pin & bush couplings to meet different needs.
Each coupling type is designed to reliably transmit torque between shafts while accommodating installation misalignments, absorbing shocks, and minimizing noise and vibration. We offer options from general-purpose equipment to heavy-duty drives and medium- to low-speed transmission systems.
    1. Jaw Coupling
    2. Jaw CouplingJaw couplings are versatile and reliable components designed to transfer torque smoothly between motors, reducers, conveyors, feeders, and other general drive equipment. Made with two durable steel hubs and a high-elasticity spider insert, the couplings effectively absorb vibration, cushion shock loads, and accommodate slight misalignments during installation.View More
    1. Grid Coupling
    2. Grid CouplingGrid couplings are built for heavy-duty drive systems operating under high torque, frequent impact, and demanding site conditions. They are commonly used in crushers, conveyors, and other equipment where stable power transmission and shock absorption are essential.View More
    1. Pin & Bush Coupling
    2. Pin & Bush CouplingPin & bush couplings are designed for stable torque transmission in medium- and low-speed drive systems such as conveyors, reducers, and general industrial equipment. The coupling uses elastic pins to transmit torque while absorbing vibration, reducing noise, and compensating for limited shaft misalignment.View More
