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. Good flexibility:
  3. 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.
