Ich habe diesen Wellenkupplungs-Adapter für mein Projekt verwendet, um zwei 8mm-Wellen miteinander zu verbinden. Ich war erst skeptisch, ob die Klemmung wirklich hält, aber ich wurde positiv überrascht. Die Verarbeitung ist sauber, die Schrauben greifen gut, und einmal festgezogen, bewegt sich nichts mehr – kein Spiel.Die schrauben sollte man wirklich ordentlich anziehen, damit die Verbindung maximal stabil ist. Ich habe sie mit einem Inbusschlüssel kräftig fixiert und alles hält perfekt zusammen.

This coupler is out of balance. It holds the shaft very well but if it is turned at anything over 500 RPM the motor vibrates significantly and anything over 1500 RPM the motor will start walking across the table.Update. This coupler has the best input shaft to output shaft alignment I have found. I can live with the out of balance issue but having the output shaft in line input is much more important so I am changing my rating to 4 stars. I will buy more to see if I got a good one or if they are all as true as the one I have.

This is a good quality, strong shaft connector. It's a pity that it didn't fit to my DC motor shaft, because it is way better than all other connectors that I used so far.

Diese welle kann einen 10PS Brushlessmotor, mit einem Getriebe verbinden ohne das die Achse durchrutscht.

Buone chiusure. Una volta chiuso rimane ben fisso. Semplice da svitare. Si può anche svitare e riavvitare più volte senza compromettere la chiusura.

The only way to go for your cnc machine. These grab and hold unlike the ones where the set screw is what hold the shaft. Had way to many of the set screw type come loose in the middle of a cut. Never an issue with these.

I wish I would have read the reviews. My motor kept stalling and I looked at everything except this junk. I mean, after all, this part is supposed to be precise. There is really not much else it has to be or do. You would think they would at least get the holes in the center. Total waste of time and money.
