A sealed and greased bearing has much less friction than a lubed oillite.  That's why we use them.  But an open bearing with even light oil will attract dust and dirt.

While a sealed bearing keeps the dirt out. No muss, no fuss!

 

Are you guys such good drivers that you notice the difference between a sealed bearing and an open bearing with light oil?  I mean... COME ON REALLY!?!?!

  Jarius back in the late 60's early 70's I think we used the SKF's. Never had a bearing failure. Unless you soldered them in and blew it. Rears only. My Pink Cans never let me down.

If you're looking to get an axle assembly, or a BB front wheel to spin the longest, use naptha to flush

out any lube and then add a bit more as your pseudo lube.

 

Whether that would translate to faster lap times, I doubt it.

 

As far as a greased BB, remember 99+ % of applications for a BB, don't involve trying to get an extra .01, racing against other guys,

with miniature racing cars.

I'm not a very good driver... been told that I really suck at it..... 

 

Maybe ? I shouldn't think about making the car go faster till I catch up.  :nea:How ever do you want it 

 

... but races can be won with the power off too .. ya know. :to_become_senile:

 

I wasn't addressing sealed, shielded or open cage .. only resistance due to viscosity and the installation methods of Ball Bearings that I personally use.

 

If you're looking to get ..... a BB front wheel to spin the longest,

 

More Roll and less Rock  :roflmao: Wheeeeeee....
