Well check this thread out. Old slot car trick with the oil-lite/sintered bronze bushing, boil it or all 50 of them in Mobil-One. Much better lubricant and a thicker body than what they will be supplied with in my own experience.
Direction; no doubt balls out; flat face of the cage to-wards the flywheel/engine. I use Mugen B0330 Super joint grease and have never lost a thrust bearing. I have seen a whole bunch of stuff work really well and it all seams to be based on its ability to adhere some sort of film at high RPM.
Whatever it is your using can be applied into a syringe for much easier application. I use syringe's from www.westsystem.com #807 three pack and there cheap. You can order or get them at any boat place.
Keeping this bearing lubed and maintained seems to be the most important things.
Next up when should it and the outer clutch bell bearing lock-up?

As I did mention you can get them at every hardware store as washers for M5 bolts, these rings are 5x10 ast the most 1/8 thrust bearings are.

Indeed the right bronze is better and I am still waiting for ceramic rings.

so with wheel bearing greese, does it stay in there?

or is it still advisable to re-greese before each race meet

At bare minimum I would recommend cleaning/greasing it at the start of each race day and before the main when your going thru everything else. If its apart for whatever reason while your there grease it.

I have used Ronny Grease (I think that's how it's spelled) but since it isn't sold anymore I'm not sure what to use when I run out. That stuff is awesome for all sorts of things..........

When the clutch engages it will create an axial force on the end of your crankshaft. Becaus the slip while engaging there is a rpm difference between the crankshaft and the clutchbell and that needs a some kind of bearing.
A normal bearing can not stand the axial forces.....

Thrust bearing is the proper bearing to be use for lateral axis movement, in this case, lateral movement of clutch bell. During clutch engage, the centax clutch will expand and push out the clutch bell outward. The trust bearing will keep the clutch bell intact.

In off road cars, they use regular bearing because there are no lateral axis movement in clutch bell.

Wanna bet ?

In electric / gas cars, the wheel bearings position in steering knuckles and rear uprights, .... those bearings are holding the wheel axle from lateral movement : The steering knuckle / rear upright is holding the outer ring while the inner ring is holding the wheel axle. Consider tire side impact, Side cornering Grip, those bearings are holding the wheel axle from side collapsing.

I use normal bearing 5x10 as thrust bearing in my NT1. Only NT1 clutchbell can accept normal bearing. No problemo with axial movement.

Then you do use 2 bearings as axial. Yes, they can stand some axial forces but if it will create play it will affect the clutchgap.

By the way the bearing will be pushed to the end tip which holds the hole bearing. Now I think about that you only did fill up the space and only the outer ring of your bearing is picking up the forces.

Arrow GREASE?

I have never put grease on my thrust bearings and have never had a problem since i have done it this way. When i put them in i always have the open side facing the front or out. I have molybdenum grease by tamiya would that be ok to use. Also wouldn't that brass bushing create friction?
