So as the title suggests... I'm looking for high quality ball bearings for brushed motors. They will be high reving motors and for on road. I need about 20 bearings so I don't really want to waste money on cheap chinese junk... but needs to be economical for rebuilding 10 motors. So not sure if that will price fancy brand name ceramics out of reach.?

I have no idea where I should look. Local Industrial bearing supplier? Specific hobby "grade" from the typical brand name RC vendors?

Any ideas?

Cheers

Try Stormer:

Revtech Motor Ball Bearings For 1/8" Shaft Brushed/Brushless Motors

Ceramics would be great, but in the long run standard bearings do great, and before ceramics, thats all we had.

But stormer has great bushed motor selections and parts!

$3.75 for ceramics... fair bit cheaper that $5 each. Anyone know any cheaper suppliers? Ali baba? lol

1/8x3/8x5/32 Ceramic Ball Metal Shielded Bearing R2ZZC

However, EMQ (low noise) vs standard. Worth it? Or just regular cleaning of standard makes a bigger difference?

1/8x3/8x5/32 Metal Shielded Bearing R2-ZZ-C3 EMQ

vs

1/8x3/8x5/32 Metal Shielded Bearing R2-ZZ

But standard vs ceramic... is it really worth the extra money? Do they last any longer? require more cleaning? At $5 ea they don't exactly seem disposable :S

standard bearings are fine once you spray them out with brake clean and add2 drops of high quality oil.
I always use Trinity Royal Oil. I don't know if they still sell it, but if they do, a small bottle is a 10 year supply. Other R/C grade oils should work as well.

Judging by some of the first time solder jobs I've seen on forums, I'd have to say brushless motors were marketed for children and non-technically skilled users who don't want to get their hands dirty

imho brushless is boring *dons flame suit*

jokes aside - re: RC / hobby grade oil... wouldn't an ATF or full synthetic gear oil be just as adequate if not better? I've never understood RC marketed stuff which are just re-labelled/re-packaged items easily available from other industries. i.e. engineering / automotive / common hardware

My method of cleaning BB is probably overkill but works very well. Quick wash with toothbrush in kero, then 15 minutes soak in clean kero and ultra sonic bath, flushed and dried + re-oiled.

I'm probably not going to bother with my current motor bearings as they were second hand and have clearly been abused + never cleaned and oiled.

Try synthetic fishing reel oil

Why? What need is there for the extra corrosion protection?

Regular automotive oils already have additives for extra corrosion protection... not to mention better shear strength, better wetting, higher heat resistance and less likely to break down over time.

Or maybe I should go with canola or maybe extra virgin?

Boca Bearings (www.bocabearings.com) is another bearing manufacturer that offers r/c specific bearings. You can search their website for specific sized bearings.

I recently picked up a complete set of steel shield bearings for my TC3 for less than $30 (24 bearings of various sizes)) through amazon.com

They also sell rubber seal and ceramic bearings.

Edit:
They also sell metal lubricants.
