i have a hodge-podge of some sealed bearings (outer axles) and regular cheap metal shielded ones for the internal parts of the trans...i did have more than my fair share of exploded bearings though...i think its from the heat/load of me heavy truck and brushless power...i'm sure mine is on the lower end of the price range...
i was thinking about getting the best bearing boca sells, but kinda pricey...did anyone try them and was there any difference???

I am ZRP
When I need a bearing set I usually buy the Teflon Sealed set that RCBoyz sells. Besides I am normally buying other items so the one stop shopping is kind of nice.

A couple years ago a guy showed me the difference between a regular bearing and a ceramic bearing. He had me take the bearing, pinch the inner race between my thumb and index finger, then spin the outer race with your other hand. The difference is unreal. Regular bearing spun a little and stopped. The ceramic bearing was like ZZZZIIIIINNNNNNNGGGGG and just spun and spun. It's like it's near zero friction.
They do make a difference, a substantial and noticeable difference but to me I have to weigh the effectiveness vs price. I don't race at the level where the difference between a ceramic bearing and steel bearing will make a difference in my results. If I was pushing my equipment to the limit and the difference in bearings would push me over the edge into the next level, then I'd probably buy them. As it stands my lack of driving skill and general lapses of concentration is the biggest deciding factor in my results. :laugh

lol...the price is what's holding me back also...i'm looking more for reliability than a performance advantage...our club level racing doesnt require the need for extracting every last hair of speed advantage...i'm just tired of having to teardown a gearbox and change some gears out when a bearing goes kaboom...and i'd hate to drop that kind of money if the bearing will still blow up on me...

As far as reliability I have no idea...when you get some let us know. :laugh

you know me too well i think...i'll probably eventually breakdown and buy a set...not anytime soon though...

Get a set of these bearings i have used these for a long time and have had great results and reliability and the price u cant beat.

Thanks for the suggestions and links! I went with a teflon set from rcboyz. I think they'll do the job for my bashing and light racing.

dollar wise and bearing foolish !!!!
Bearings have a bearing on a lot more than the bearings Wo I had to read that a second time.
First of all, the first thing when using brushless is to change the motor bearings to ceramic balls with stainless steel races. Only then can you think about the other bearings.
By the way, use at least abec 1 rating but not passed abec 3.

so i emailed boca bearing to ask about their bearings in my truck...here's my original email:
hello, i was thinking of buying a bearing set for my tamiya
clodbuster...i was looking at kit numbers: #55-065C-YS or
#55-065C-YU...between the yellow seal and ultra seal versions...the
truck will primarily be run on grass, but we may hit an occasional
dirt patch...would the yellow seal be a better choice for this
application? also, my truck is modified from stock, and is
considerably heavier and runs dual brushless motors for more power and
rpms...i have had several bearings explode under use, and was
wondering if your bearings are warrantied or have a better resistance
to failure...the failed bearings i have are from an unknown source...
also, since i run the MIP cvds in my truck, i was wondering if two of
the bearings in the set could be changed out for two of a different
size i need to use the cvds i have...any help you can give me would be
greatly appreciated. thank you.
and the reply:
Thank you for your email. We would recommend our Yellow Sealed bearings for your application. This type of bearing would keep the dirt and dust from getting into the bearings. I understand your concern about the bearings holding up with your modifications. Sorry, there would not a warranty for this type of bearing failure. I believe you would have this issue with any bearing you are using, it sounds like there is too much load for any bearing to take over a period of time. You may need to modify the part to accommodate a larger bearing. Sorry, we can not modify the kit components as they are priced accordingly. Please let me know if there are any other questions.
looks like i'll stick with the inexpensive bearings...no sense in dropping money on the expensive stuff if the manufacturer thinks they may fail under those circumstances as weill...

You must start with the motors. Change the motor bearing to ceramic balls in stainless steel races teflon sealed. ABEC 1 to ABEC 3, then start thinking about the others.
Good Luck

That is a great idea except...if you read he's not having motor bearing failures, he's having failures further down the gearbox.

I put ceramic bearings in my clods, and did not notice a gain in HP or run time,
I had MANY of the ceramics seize up on the knuckles, and outside bearing of the axle tube from running in damp grass, or just spraying the truck down with simple green, and air hosing it off.
"A" reason some "special" RC bearings spin so free is, they apply only a super light oil.
You take most industrial- general purpose bearings have a thick oil or grease in them.
You can take the sheilds off, spray them out, and put back a Drop of light lube, and you will have a spin forever bearing..
And shielded bearings don't have a contact patch to give friction.
a SEALED bearing the rubber rubs on the innner race, giving some drag.
The only ceramic bearing I cared for was the 5x8mm one for the gear sets.
I don't believe there is enough shaft speed on the axles to warrant the ceramics.
Now on a brushless motor YES, maybe the first gear that the gearbox has that still has some high rpms.
Other than that, what ever I could get.(except for the 8x12mm that thundertech sends with their cvds, they bust up, fall apart FAST in my use)
Unless you like having $100's in bearings that might not last as long as the regular type at times.

I have always used the blue rubber shield bearings and never had any problems i noticed only a small increase in drag but good enough too do what i needed and they hold up to a beating and dirt,mud and violent crashes. my bro and i have just Bashed stuff to death.:tmb

Always great help in this forum.
Getting back to the bearings. ABEC ratings are the tolerance ratings as applied by the American BallBearing Engineering Council. Yes bearings are that important in all of our lives. Ratings for people like us generally are from 1 to 7 with 1 being the least acceptable tolerance to receive a rating. No matter the materials, if you do not at least have an ABEC 1 rating the bearing is crap. If not using ceramic balls, I understand the cost, at least use ABEC 1 all stainless steel. Oh, also get teflon shielded. Oh OH bearings care for us we do not have to care for them. I think we do not understand their importance fully nor do brushless manufacturers give us great info other than to say, we use high quality bearings or, we use abec 1 bearings, all of which adds up to zilch.:tmb
