Looking for PM25MV Spindle Bearing replacement

[miketod09]

I was doing some maintenance on my mill this weekend and the spindle started making bearing noise and I would like to replace the bearings with a higher quality product.

Does anyone know of quality replacement bearings for the PM25MV?
P/N if you got it.

Thanks

I suggest you pull the bearings and look for the designation, then find a bearing to meet your desired level of accuracy. I should think an ABEC 5 or possibly a 3 would suffice.

I changed mine to angular contact bearings. I used 7007B and 7005B bearings. You need to make spacers to use them since the tapered rollers are thicker, but it is not difficult to do.

The ones I used were from VXB and were part numbers KIT8891 and KIT8889. I have run them up to 10,000 RPM without trouble, though I can't speak to their longevity yet.

Yes if you are going faster, I would get the angular contact. If not, the tapered rollers are just fine.

Bearing #s are 32005 and 32007

I am contemplating upgrading my PM25 spindle for higher RPM. I tracked down the bearings you used and have a question

Can you describe the spacers that are required?

I appreciate it!
