    Tips: Flexible Shaft Coupling Features
    1. Zero clearance: The entire coupling is not allowed to have clearance during transmission.
    2. Low inertia: On the basis of ensuring the transmission strength, the weight of the coupling should be reduced as much as possible.
    3. Good flexibility: The precision coupling needs to absorb the deviation between the shaft and the shaft produced during the installation process to a large extent.
    4. Compact structure: The shaft coupling is usually small in size, and its clockwise and counterclockwise rotation characteristics are exactly the same.
    5. Maintenance-free: After the shaft coupling is installed, there is basically no need for maintenance, and the installation is extremely convenient.
