Description of Sydien Coupling Aluminum Flexible Connector

Shaft Usage: 8mm to 8mm / 0.31 to 0.31 inch;Outer Diameter: 20mm/0.78", length: 25mm/0.98". Unique balanced clamp screw design reduces vibration while the cross cut increases clamping ability. Flexibility of coupling shaft removes stress between the motor and driving components. Machined from a single piece of aluminum with multiple spiral cuts for higher torsional stiffness and torque capabilities. Shaft coupler Often used to connect servo motor, stepper motor, encoder, screw driving, machine platform, etc.

NOT like the picture - subtle but crucial difference.

Article not as shown. I was looking for a very specific piece of hardware, looked everywhere and thought I found it. Turns out this is the same cheap, barbaric design I could buy from any other seller on Revain. Very disappointed. I think I've been using Amazon for a while.

Pros
  • The flexibility of the connecting shaft relieves the engine and the drive components.
Cons
  • thin

Couplings are as per description

The description corresponds to the parts. On the main image in this post they look like 5mm to 8mm clutches but they are actually 8mm to 8mm as stated in the description. However, the clamping method fits the picture: There are no set screws, but actually screw clamps. I will update this review if I run into any issues over time, but none of these have happened in the 2 days I've had.

Pros
  • . Manufactured from a single piece of aluminum with multiple helical cuts to improve torsional rigidity and increase torque.
Cons
  • Crumpled

Just save yourself the trouble and buy real clutches.

I received 2 packs to inexpensively size my CNC router to the right size. They are. Work. I think. One of the clutches I received from 4 was the wrong size. I needed 10mm x 8mm connectors and this one was 8 -> 8. I probably should have returned the part at that precise moment but for some reason I didn't. In my (weak) defense, my budget was too high, which is a rookie mistake with this type of project because they are black holes of money, time, and sanity. I tried drilling the wrong coupler

Pros
  • Shaft Coupling Widely used to connect servo motor, stepper motor, encoder, screw drive, machine platform, etc.
Cons
  • Out of fashion
