Yes, four square balls .

Just listened to the video and I have heard people talk about the settling of grease in bearings (clough42 channel where he showed a very nice spindle with PDB made in the US that had a small amount of chatter). So my own view is that it can be a cause but this sounds too loud.

My bet would be the bearings are skipping around as the noise is quite loud. Are the bearings a press or good fit on the spindle shaft and housing? Wonder if they are machined out of spec?

Do you have tools to measure the fits ?

If the bearings spin nicely in your hand try loctiting them place if you are looking to try and repair it yourself.

I've been looking for the difinitive "How to dissassemble, re-grease and reassemble your 2.2Kw water cooled spindle without breaking it" thread but haven't found it. I'm sure a list of key pointers to what you must and must not do and what tools you must have before you begin would be much appreciated by many readers contemplating a check of their bearings. Is this something the pro users do regularly?

It's a pita because you must fabricate your tools, and even they easily breaks (only 2.5mm pins...). You must heat at least 3 minutes in full power with your heater before trying unscrew this "#&@% full of holes". I enlarged them to 5mm,. But after this first victory, there's another flange. End of the story for me.





The 6002 bearing must have the large side pointed to the top. It's not a radial bearing.

Hi Jonathan,

I have just put together WorkBee 1000 x 1000 mm CNC machine. I am totally intimidated by the electronics. I purchased this machine from a firm in China and the directions for electronics are either nonexistent or (for me) undecipherable. Can you put me in touch with anyone who can walk me through this electronic challenge?
I have a Huanyang GDZ-80-1.5 11V 1.5Kw 5A 400Hz spindle, an HY01D511B , an LRS-350-24, a UNO cardstepper card.
Thank you for your time.
