The 2.2Kw Chinese Spindles - Info, Setup and Advice + More

**Jonathan** · 10-07-2015

I recommend checking with a multimeter what the resistance it between each of the pins, as who knows if the companies making these spindles are consistent. You should get a couple of ohms between the motor terminals and zero ohms to the spindle body, or high impedance when they don't bother with the earth.

Hi everyone.

FYI, I just ordered a complete spindle kit from Kevin Ho at ROB BEARING AND MECHANICAL PARTS on AliExpress.

They don't sell it as is, but if you contact him they'll make you a better price than the kit for which I gave the link. Instead of 417 Euros from the original seller (288€ kit + 129€ shipping), I paid 360€ (US $400 round !). I haven't received the kit yet, but I have made quite a few orders with this seller and everything arrives on time and in great condition. Always well packed. He's even offered me some couplers I had forgotten in my last order. It's a factory that produces linear motion stuff but they can order anything you want.

I'll post pictures of the kit when I receive it, but I have no doubts it's worth the price.

Only thing missing is a nice bucket of water, that will prevent you from having to buy a radiator and a fan. With 20-25L bucket you're good to go... you'll be long dead before your spindle raises the water temperature by 10°C !

Hi,

I have a question about water pump. What is the size of the coupling for the hose (pvc 6mm one)? Where I can find this?

Thank you
Gabi

Hi !
The pipes I got with my kit were PVC 6mm. However, I do not recommend those. Personally I find PVC too rigid and prefer much more plastic hose used in gas powered remote control airplanes. If there is a store close to your house that sell that kind of planes, just get it there. It's quite cheap. Otherwise you can order it online :)

I have the pipes. my question was about the connection. The brass connector.
On mine (pump) the seller said is 18mm diameter outlet. I cant find anything with that dimension at one end and with 1/4" or 6mm on the other end.

Weird :/ Mine is different. It's made of plastic, exactly like the one on this kit:

Though I have to admit it was quite hard to fit the pipe that came with the spindle. The coupler I have has the same size as the one on the spindle.
