Outrunner Spindle Parts?

[blackburn mark]

So, do I need angular contact bearings for the spindle? It isn't too much work to make the extra support part. I think I'll still make it short though, perhaps them I only need the two bearings at the end. The original design used deep groove so I think I'll do the same. I can't find any angular contact types with such a small ID as 8mm.

larger spindle is the easiest to make/ it has a 10mm shaft so just buy a 10mm(C10) ER collet shaft and one or two double row angular contact bearings (3200 5200 bearing ebay) they are already pre-loaded... very simple to impliment

the 8mm shaft is a little more complex as there is no equivalent double row A/C bearings so you need to buy two magneto bearings (small A/C bearing) and pre-load them
i have used standard skate bearings on my 8mm shafted spindle and pre-loaded them with belleville washers, not ideal but iv had no problems so far and if the bearings die they are easy to replace and super cheap

let us know how you get on :)
