i have looked into these before and they truely are the technology of tomorrow... i bet you will start seeing these become increasingly popular in the next few years

on another note... i wanna start experimenting with needle bearings down at the machine shop... i just need a good project first

Too sensitive for use in a turbocharger, and they stopped putting them in car engines decades ago for a reason. Maybe in the suspension, hrm?, with a roller thrust bearing to control axial movement.

these things can support insane amounts of pressure/weight right? and how many start/stops does the average turbo/ball bearing turbo hold up for when properly maintained?

i was thinking sway bar mounts, just for fun

i bet they cost a ---- ton also and are probably not good for daily driving because they have to stay at a high speed to work rite so you would accelarate the wear if it was spinning to slow but that ---- would be awesome for all out drag

Roller bearings are maitenance nightmare. Their used on the swingarm suspensin on dirtbikes they don't last real long and if you don't clean them regularly they get flat spots and seize up. They ned a real light grease to work well. if you use regulare grease they stop working pretty quickly.

the needle bearings in the rod last pretty good though. the crank bearing lasts really long about two years. and the one on the wristpin gets change every two months or so with the piston.

On a side note, baller bearing turbos are even more sensitive to oil pressure problems than journal bearing turbos are, especially the low pressure turbine stuffs. I see where you and skitter are going about the technology's limitations so far I just wanted to point out that where the technology is now isn't all that great.

I'm wondering if a little compressed air can't be blown in the housing under operation to actuate the foils?
