Pipe center DIY

Hi Ken. Maybe you misunderstand the reason for using double angular contact bearings in this project - and in car wheels which they are made for?
Angular contact bearings ARE thrust bearings, as well as radial bearings. By using a match-ground pair inside a single outer track ring, they have no backlash and can take the thrust a car can impose going around a corner really fast.... or a work piece being clamped against them.
No need for a separate thrust bearing.
I used the bullnose/pipe center today and it woks like a charm. Thanks again cascao!
 
this is how car wheel bearing I've used look like.

they have two internal race in one asembly witch give right amount of preload. and good seals in a cheap package.
as mentioned before, the loads they suposed to deal when in a car is much bigger than in a pipe center....

for who didn't like the idea of using car bearing, this same kind of unit is sold by bearing manufactures in their industrial catalog.

Ok, I think I understand. Maybe I'm just paranoid and over build things.
