3. Applications of the GR/HR Cardan Coupling (Universal joint Couplings):
The precision joint GR/HR product, a flexible shaft coupling, is commonly used to connect shafts with varying degrees of flexibility, eccentricity, manufacturing tolerances, and installation errors. Additionally, the GR-HR Cardan shaft coupling plays a crucial role in transmitting high torque between power transmission systems placed at a distance from each other, where there are constant changes in distance and position during operation.
