PEEK Polyetheretherketone washer?

[Alfa Spirit]

Hi,

Do you use PEEK washer between the DD and the strut?
I know PTFE teflon but I don' t know PEEK Polyetheretherketone, if you have experience with PEEK, this material is highly suited to applications that require a high performance ...

Thanks

nowasher. A gap with the distance from drive dog to strut equal to the diameter of the flex cable.

Why washer???
You need space there. Just like post #2 stating....

No washer?

[Rumdog]

how will you compensate for cable windup? With a washer there, it will put extra stress on the flex cable leading to failure and it can add extra load on the motor.

nope. no washer.

Nope....
Check on post #2 for proper spacing please.....

Yes

[Rumdog]

well, in that case, it should work fine i suppose. A thrust bearing may work well too. Just curious, why not the regular type strut and flex cable?

@ Rumdog, have a look to the picture.
