LM Model
This metal coupling utilizes the elasticity of a spring mechanism and incorporates a metal coil spring. This model offers high flexibility and is capable of accommodating significant misalignments, such as eccentricity and angular misalignment. The LM model operates at a relatively low continuous torque; the hub is made of aluminum alloy, and the coil spring is made of stainless steel.

- The maximum rotational speed does not take dynamic balance into account.
- The moment of inertia and mass are based on the maximum bore diameter.
