ceramic ballraces

[Merciless]

just thought i'd say "THERE WORTH THE MONEY"

;DVery free car ;D

These are expensive. You could just lube your bearings with a different oil.

[Chris Kerswell]

What makes them sooo good then?

[AzNDRAGster]

You don't have to use lube/grease, and they'll still be smooth. Its the same thing as using carbide diff balls.

[Stu_Dale]

They wont rust either arfter a race in the rain which can be a problem, (espesialy in britan). true they are expensive but as with every thing in this world you get what you pay for.

well i like them. paid about £55 pounds for the proper yokomo ones.PM me for the shop info if you want it.

VERY VERY free is why there so good !!

[MattWinyard]

So you can run them with no oil?

The only problem with ceramic balls is that if you get a bit of grit in them, ceramics dont like grit... they chew up....

I advise a blast with motor spray after every meeting ... or if you get time, every run!

Yeah, you still need frequent maintnece.

[Stu_Dale]

Im not speaking from experience but i thout the ceramic bearings were harder than normal ones so shuld be able to take more punishment.
Could be wrong tho.

[AzNDRAGster]

Yeah, since their harder the grit scratches up the bearings inside the bearing and it makes them less smooth.

[AzNDRAGster]

And if you ever have to relplace one it'd be more expensive than a normal bearing.

Since when was racing EASY.You still have to maintain your car no matter what stuff you put in it.

I was mearly say the ceramic ballraces are the best i've ever used and they are very very free.

I you want ballraces you never clean i sudgest rubber sealed with a thick grease filling so as not to allow rubbish in them.

Otherwise race the best ballraces you can get and clean them regulary ;) ;)

Hi friends. Greetings from Malta.

There seem to be different schools of thought about bearings.

LINE 1. Buy the most expensive (ceramic). They must be best.

LINE 2. Buy the cheapest and change regularly.

Different guys have different opinions on this.

I recently discussed this with a top line UK driver's dad. He told me he always ran his son's cars with the cheapest bearings. Just washed them out, sprayed with WD40 and fitted. He changed them regularly but admitted that a year's supply was still cheaper than a set of ceramics.

This guy's cars are always ballistic. So which is the right way to go?

Can we have some more expert opinions please.

Here's another one. Do you run the diff crown wheels on TC3s and Yoke SDs lubricated or dry.

Regards

Joe from sunny Malta.

[Chris Kerswell]

Run average bearings then you get the best of both worlds!

I run the crown wheels dry but the grease that spins out of the diff lubricates the whole inside of the gearbox!

[burgie]

I run the crown wheel dry most of the time, as I find that when it is greased, this appears to give a certain amount of "mechanical" braking effect, especially off power.

As for the ceramic bearings, they are bound to have less resistance than oiled bearings, by their nature, but as for grit scratching them, I wouldn't like to say if this would or wouldn't damage them, as the amount of grit that will get to them, and potentially damage them, on a properly maintained car, should be minimal. And the sort of people who will buy ceramic bearings will maintain their cars properly.

Yeah, I know, so much grease spins off the diff.

[atlas copco]

Well if the crown wheel and pinion required some sort of grease it would have come in the kit .if you grease them you would cause drag and as you know some people spend hours washing out bearings to get a drag free drive train so i say NO to any kind of lube

[AzNDRAGster]

I wouldn't put grease there anyway. . . . . Bearings have lube on them from the factory.

[BC Rog]

I agree, the diff gears grease themselves!!

If you want free bearings without running the risk of them failing prematurely try this;

get an old pan and some sawing machine oil.

heat the oil in the pan to something like 60-70 degs.

Remove the rubber seals and drop the bearings in for a few minutes.

Leave them to cool in the pan for a while then take them out and let them air dry on some kitchen towel.

Refit the seals (ouside of bearing only if you fell like the last 1%) then clean the excess oil off the outside. I use some motor cleaner soaked into a kitchen cloth .... don't spray cleaner at the bearings.

There you go, smooth, free and reliable bearings.
