UH1-Pro|L is a direct replacement to the stock hub that comes with all three models of the Simucube 2 family of direct drive base systems and also for VRS/Mige servos with the addition of the optional drivelock accesory.
It adds 123mm extra length to the stock hub and with smaller diameter is the perfect add-on in order to extend the motor shaft and give enough room and clearense for you center monitor in order to be as low as possible and to bring it closer to the servo axle.
Its total lenght is 173mm from the front face of the servo to the mounting surface of the QR.
It is compatible both with the stock Simucube 2 quick release providing a seamless conection with it and it can also be compatible with any PCD70 QR on the market with the addition of the optional adapter.
The UH1-Pro/L is also compatible with out ProXT modular extensions for those that need more than 123mm extra length.
If you are having problems unlocking the drive lock that holds the shaft use one of the 4 M6 bolts in one of the 2 threaded holes circled in red in the picture below, once it bottoms out half an extra turn clockwise will unlock it. We suggest to leave a 5mm gap from the servo frame when installing the UH1 to avoid rubbing.
