Feature: 1. PA66 Material: The rubber body of this rigid coupling is made of PA66, which has good wear resistance, erosion resistance and electrical insulation. 2. Sliding Design: This rigid coupling has a sliding design which allows for more effective compensation of radial and angular misalignment. 3. Easy To Install: This rigid coupling is detachable and uses clamping screws as a fastening method, making it very easy to install. 4. High Torsion Transmission: This rigid coupling is used for high torsion transmission, which allows for better absorption of vibrations and makes this rigid connector responsive and less prone to loosening. 5. Wide Application: This rigid coupling can be widely used in the shaft transmission of various mechanical devices, such as water pumps (especially high power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), naval high speed power transmission system, steam turbines, piston power mechanical transmission system, crawler vehicles, and generator sets of high speed and high power Mechanical transmission system.
