    Angry Chinese spindle 2.2 kW funny noise

    Hi there,
    I just installed a new spindle, 2.2 kW water cooled, Chinese.
    Before using it I made it run at low speed for 2 hours and then increased the speed gradually.
    I have a funny noise between 8000 and 24000 RPM which comes and goes with and without load on the spindle.
    I have recorded it .

    There are no vibrations on the spindle and I have no idea if this could be a bearing issue.

    What do you think? Is it faulty?

    Sounds like an outer race spinning. Not good.

    It also sounds like fluid bubbling. Does that sound change at different speeds?
