Rigid Coupling Descriptions
- The rigid coupling is made of aluminum alloy, which is particularly resistant to oil and chemicals.
- The hard aluminum alloy material ensures the low inertia, high sensitivity, long life and maintenance-free of the rigid coupling. At the same time, the clamping rigid coupling has the common characteristics of high torque rigidity and zero rotational clearance of the coupling.
- The rigid shaft coupling is a coupling composed of an integrated structure. It can perform excellent performance under low speed, high speed and high torque conditions. It is a coupling with extremely high cost performance.
