According to this month's machinedesign article, steel bearing microwelds itself onto the race as it rotates causing heat build-up. That also cause increase friction.

Ceramic also spins much longer.

Uh, what do you think heat dissipation means?

Head dissipation means to remove heat from an object...lower friction of ceramic prevents much of that heat from occurring in the first place.

I will get to the point of having to replace all my berrings hopefuly not till the end of the season but when I do I would like to get good quality and low maintiance berrings. I know Stock (Economy) berrings can be verry restrictive so you have to pull the shields and de grease them I know (as been talked about) ceramics is the best way to go but what is my 2nd best? there are so many choices I don't know what im getting. the berrings would go into a Associated TC3.

There you go Jack.

Thank you, inspector. You guys do know something about heat in Hawaii there sitting on one of the hottest geological features of our planet.
