DIY Spindle - What type of bearings are best suited for a spindle.

[routercnc]

Hi Shaun,

I hope I'm understanding your intention. I'm no spindle expert, but a thrust bearing will only allow you to drill holes because it cannot take side loads. Therefore a pair of angular contact bearings sounds better. A spindle often runs at high speed, and therefore you might also want to consider the ceramic type of bearing.

Bit more detail about what you want to machine might help others with a spec for you.

Thanks

Hi Thanks for the reply, I have found a couple of roller type thrust bearings in a rummage through a box of old bearings I got from my Dad...I was going to use a couple of ball races and a thrust bearing.
I don't need anything too robust as I'm only going to be cutting depron and balsa / liteply at first, but was worried about the speed...My thoughts were like a model aircraft engine is reported at XX BHP at like 17,000 revs ( although I have never measured or seen one at this speed ) now these are just ball races and have temp and nitro working against them?? It would be good to continue the 22mm OD theme of the skate bearings but the shaft on them is only 8mm
Just noticed your Avatar - Is it your own design? Are you going to green acres fly in this weekend, thats in your neck of the woods ?
