I need a shaft coupler. This one is labeled as "flexible". What is meant by flexible in this context? Does it simply mean adjustable?

It usually means that a slight non-parallel alignment of the motor shaft and driven shaft can be accommodated.

Depending on how much power and RPM, you can also use a piece of flexible vinyl tubing (hose).

 

Hello,

The flexible means that if the two axis are not perfectly alligned, the coupling will adapt the allignment.

It would help if you explained more graphically what you have in mind

 

Are there disadvantages of using a flexible coupler over a fixed one? I want to spin a PCB from a motor.

I found a through hole slip ring BTW.

Back on my propeller clock idea.

I would agree, I would use something like Automotive coolant hose cut slits 1/2" 1/4" etc depending on the size shaft your looking for don't exceed 4 slits from the middle to just where you plan on attaching it clamp etc.

I doubt you need a flexible shaft for that. The pcb is already flexible enough and won't cause enough stress on the motor's shaft if it's rigidly coupled for you to worry about.

But for whatever reason the flexible ones seem to be cheaper and more plentiful. At least on eBay / China.

 

I think a flexible coupler would be a disadvantage for your clock app. The least imbalance in your pcb would result in large-amplitude wobble.

Good thinking

 

If you get the helical type coupler as shown, the S.Steel version is far better than aluminum where torque is an issue.
