Tips: Flexible Shaft Coupling Features

Zero clearance: The entire coupling is not allowed to have clearance during transmission.
Low inertia: On the basis of ensuring the transmission strength, the weight of the coupling should be reduced as much as possible. 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.
Compact structure: The shaft coupling is usually small in size, and its clockwise and counterclockwise rotation characteristics are exactly the same.
Maintenance-free: After the shaft coupling is installed, there is basically no need for maintenance, and the installation is extremely convenient.

Works great for my application

Recently a new laser cutting machine was installed in the office, I tried to buy several types of couplings, which I have used and done well, the price is acceptable to me, the processing is perfect, the appearance is exquisite and beautiful.
