Acer all the way. Regarless of what other say, Acer uses the highest quality ceramic balls available (some are confused on the quality rating system). They do get better with time. The seals require little to no maintenance and they are plastic so if you get into an accident, the sheild will not bend into the cage and ruin the bearing as metal cages will do. They also keep dirt and stuff out of the bearing about 100% better than any other seal. I have never had to pull a carpet fiber from my Acer Ceramics.

I feel many that have tried Acer ceramic bearings make a big mistake. When new the Acer Ceramics will not seem as free as they should so many clean them and relube them before they have been run....big mistake in my experience. These bearings need to be broken in and I recommend breaking them in as they came from the factory. After 10-20 runs, these bearings are incredible and get better with every run. 1 set will last you forever!!
The highest quality rating I've found is Grade#3 (the lower the Grade, the better/smoother the bearings) which comes from Boca; Acer doesn't use the 'highest' quality ceramics, I think theirs are Grade#5 (which isn't shabby AT ALL).
I'm using Acers right now, and love 'em but have to admit, I did clean them out and put some Trinity Royal oil in them. My Yoke spins for about 9secs though. If you're counting that out loud, that's pretty long. Boca's are 196.00 dollars for a set, WHOA!
I don't know what other manufacturers are using for their ceramics, but some ceramic bearings can go as 'low' as Grade#25...

what grade the Yokomo set is would you? I recently got a set but haven't put them in yet.

Ps: 9 seconds is that all.

Sorry but you've got that backwards. Higher ABEC # =tighter tolerances(Higher quality and longer life). A lower ABEC #, is, of course, the opposite.
Generally, the higher ABEC numbered bearings are worth it. I have had a set of ABEC 7s in my hockey skates for around 4 years now and they still spin like new. Granted, there is very little side load on the bearing compared to RC use, but, 4 years of constant skating would've killed any lower grade bearing.

I've never heard of an ABEC 25 bearing. I googled it and never found anything on it either. Diff balls are often grade 25, are you thinking of those?

Look harder... anything worth finding takes work.
Are YOU sure? Reading up on Acer's site when I ordered my bearings, they mentioned the same thing I said, the lower the Grade, the more round and smoother the bearings are. Boca's site says the same thing or am I misreading something... the ABEC Grade rating is the rating on the balls within the ball-bearing assembly; I didn't make it clear earlier, but yes grade 25 are often diff balls but Boca sells 1/16 (thrust balls) and 3/32 (diff balls) for my Yoke @ Grade#3...
For interested ones, look on Acer's site under Differential balls; Grade #25 is the lower grade that alot of other manufacturers sell

Quick google search found this.....

ABEC 1 – good durability, good beginner bearing, slow spin
ABEC 3 – faster spin and a great intermediate bearing choice
ABEC 5 – great top speed and increased durability
ABEC 7 – fastest spin, top precision, very tight bearing tolerances

Post Correction...

I'm getting the two mixed up, yes the ABEC rating is talking about the bearing tolerances, the higher the rating the closer it is to being 'dimensionally' perfect ...

...and the higher the rating the smoother, faster, and better the bearing. ABEC 3 bearings are regarded as crap by most skaters,skateboarders and even yoyoers. it's the complete opposite with diff balls which aren't rated by ABEC.

Now you've got me confusd? on the site it say's contrary to popular belief the lower the abec # the smoother and rounder and faster the bearing is? I'm going back and reread it for the fourth time.Okay I reread it,it does say the lower the # of the balls the better the bearing,so I take it you need a bearing with a low ball # and high abec # Hmmm! Correct?
