Looking for the best clutchbell bearings, bar none!

Acer bearings lasted about 2 gallons before dirt got them. Which is very nice.
Now I use ABEC 3 ceramic bearings from one HK store (abec35). Been using their ABEC 3 and 5 ceramic, steel and stainless bearing for couple years and never had eny issues with them. And standard steel are way under 1$ depending on size.
Ceramic for clutch are about $3.80 per piece

I use the Protechs. I change them between the heats and the mains, and run the ones I have in there the following week in the heats. They are $1 a piece, so I always start the mains with a new set. I have not had a breakdown in a heat or a main yet.
Hope this helps.

I`ve been using Avid Revolutions for years and they last at least as long as the shoes do . I just change them when I change shoes just to keep fresh ones in there . I agree , bearings are not the problem , look at the engine , flex , shimming and if your meshed square to the spur .

Cheap bearings from walawala off ebay degreased and oiled with acer sin lube works ok for me, when i de burr the shoes i add a drop of oil to re-lube the bearings, a dry bearing will be gone in no time

Try ReadyRollers.com
Ive been using these for the past year and have been very happy. The rubber shielded ones are green just like another brand known for quality. These are not your typical $1 bearings.
When talking to Jerome the owner of Ready Rollers he has told me there are many different quality bearings available from his supplier he buys the higher quality ones and some of the competition doesnt. Give them a try if nothing else the price is right.

I just bought 4 Avid Revolution bearings for my clutch on my buggy, If your ordering there item of the week or what ever as long as its under 40 dollars its shipped for 2.79 so i got four bearings and a sticker sheet for like 7 bucks with shipping, i would have paid that much for 3 crappy bearings at my hobbytown and it wouldnt have come with the best thing ever! STICKERS!!!

ACER Racing ceramic clutch bearings
Hi guys, the problem with the 5x10x4mm clutch bearings that are used in most clutches is that they are way too small to handle the high heat and stress of todays powerful engines. Thankfully some companies like XRay have responded by making larger 5x12mm bearings that can better handle this stress. Others like Losi have creatively made a 5x13mm inner bearing and a 5x10mm outer to relieve a lot of the stress on the bearings.
What ACER Racing has done in our 5x10mm clutch bearings is change the internal tolerances of the bearing race and cage, add our Ceramic Nitride Pro Series balls inside, then we use our SIN synthetic grease (not oil) to keep the bearing really cool. You cannot use oil in a 5x10mm clutch bearing as it can't cool down the clucth bearing well enough. All our other ceramic bearings are lightly oiled but clutch bearings must be greased.
Try our 5x10mm ceramic clutch bearings, they are backed by world and national championships and are the best money can buy for all you hardcore racers. They are $7.99 each with FREE airmail worldwide (no minimums!)
We also make the 5x12mm and 5x13mm clutch bearings for XRAY and Losi racers.

Also, the Boca Yellow Seal ceramics come recommended and I have a couple to try because I was confused about the sudden problem with my Acers. And I hear that the special clutch bearings from TKO are highly recommended as well and a 10 pack gets you in under $3 a bearing if I remember correctly.
Boca Yellow Seal Ceramic, Acer Ceramic special clutch use, TKO clutch bearings, or Avid based on my experience and what I've paid attention to over the last year here
Also, remember some of them have oil in them and need to be blown out and greased if you want them to last. It says so right on the Avid web site.
Check out that engine too if all of your problems are recent.

Almost had my full head of hair pulled out when bearings after bearings kept failing within 1 tank. Culprit - worn engine's pilot shaft where the bearings sit causing too much play even with brand new bearings. I might have ran my 3 reputable engines for far too long as all caused the same bearings smashing problem when play was noticed. The problem goes away after the worn shaft was sawn off and a new pilot shaft with attached flywheel nut(those meant for engine without pilot shaft) was used.

can you confirm the ACER SIN lube is different to the SIN grease, i have had a quick look on the Acer site and cannot find this grease ? i have to admit i use SIN lube for my clutch bearings and re lube them when de-burring the shoes they last ok like this with cheap bearings and boy does the clutch spin well
