This is an important thing we must know before purchase. There are two points we need to check:

• Volts

There are two options, usually: 220 volts and 380 volts. So you should know which one you will go with. The answer should be on your actual spindle nameplate. If you get a spindle with the wrong volts, it won’t work with your machine at all.

• Diameter

It is 100mm for the 3KW water cooled spindle. Kindly check if your actual one is the same 100mm from the nameplate. If you get a wrong dimension (not a 100mm spindle), it will not fit for your spindle holders, and the result is you can’t mount it on your machine.
