Key Features

1. Effective Vibration and Shock Absorption
   Equipped with a star-shaped elastic element, the LMZ-I coupling effectively absorbs vibration and shock from the transmission system, protecting machinery from excessive dynamic loads and extending its service life.
2. Compact and Lightweight Design
   The coupling boasts a small radial size, lightweight construction, and low moment of inertia, making it ideal for medium-speed and medium-torque transmission systems. Its simple structure requires no lubrication, reducing maintenance costs and downtime.
3. High Adaptability and Durability
   Designed to handle frequent starts, forward and reverse rotations, and harsh operating environments, the LMZ-I coupling performs reliably within a wide temperature range of -35°C to 80°C.
4. Automatic Misalignment Compensation
   The elastic element deforms elastically to compensate for any axial misalignment between shafts, ensuring stable operational performance and minimizing wear on connected components.
5. Robust and Reliable
   With a high load-bearing capacity, the LMZ-I coupling is ideal for applications requiring consistent performance, such as industrial machinery, pumps, and power transmission systems.
