Outrunner Spindle Parts?

[Tenson]

I bought a couple of angular contact bearings 708A from eBay but it will take a while to arrive from the USA, so I'll use deep groove first just to get going then 'upgarde' and see the difference. I doubt I need anything like 12000RPM... this is going on a CNC3040!

unless you have ordered the deap groove bearings allready you might as well get some cheap skate bearings, they are dimentionaly the same as the 708A
i also bought a pair of 708A but that spindle is still running fine with the skate bearings so i havent needed to fit them yet
iv pre loaded the skate bearings with belleville washers the same as i would with the 708A
