Default V-ONE RRR WC Edition Bearing Reference

For what it's worth, attached is a bearing refererence for the V-ONE RRR WC Edition. For readability, change the font to Courier New.

On thing to note about the Boca Bearing Kit #25-420C-YU for the V-ONE RRR, is that it only includes one 5x8x2.5 bearing for the clutch (none for the throttle arm) and one extra 5x10x4 bearing for the Clutch Bell, Rear.

37 shore are for?
40 and 42...

any advised??

..Nope....it all depends how good the bite is.......thats what determines the compound of tire to use...low traction softer....high traction harder.....bottom line is if you can get your car to rotate with a harder tire the faster you will be..setup, tires, body all help...

Default Boca Bearing Ultra Seals - "Maintenance free and lubed for life..."

This is what Boca Bearings had this to say about the Ultra Seals:
Quote:
Thanks for getting in touch. While you may be able to extend the life of an ultra seal bearing by opening it and cleaning it, you will void our warranty. Lubed for life means it is lubed until the bearing starts to feel gritty, when this occurs it is either time to replace the bearing or open/clean it. but from that point forward the bearing would not be covered by us in case of failure. The biggest issue is that you can very easily damage the seals or shields. The Ultra seals are not water tight, there is no bearing that is water tight sealed, even the most heavy duty seals are just water resistant. So opening and cleaning is really your judegement call when you feel as though your bearings are getting towards the end of their natural life. Hope that helps, let me know if you have anyother questions.
Well, that answers that question!

rmdhawaii, it occurs to me that you really want to try these bearings. whether they do provide the performance bang for the buck is of personal opinion. in truth, many upgrades we do to our cars do not improve our lap times at all, but they sure make us feel better about our cars, and i am certainly guilty of that. but this is a hobby and you should have fun with it. so if you can afford it maybe you should try a set and you can decide for yourself.

The wheel bearings especially outside ones tends to go bad easily. Bearings in the drive-train usually last a long time.

Please note that I have very strict standards when it comes to bearings. A lot of bearings I replaced might be consider good by others. I will replace them if they feel the slightest grittiness and not complete smooth.

I have to say that the Boca Ceramics are meant to last at least 16 races.

If they fail before that, then sometimes they will replace them at no cost.

Ceramics are the way forward, micro bearings in RC cars just dont handle it like above. Ceramics are lighter, freer running, last longer, and resist corrosion.

Its a no brainer. Why replace crappy bearings all the time when one set of 130 ceramics can last the season? (roughly)

What a stupid idea.


Get the titanium hinge pins, balls, and suspension pivot balls.

Ive replaced most of the metals with titanium, and the difference is amazing, the car is SO light you can feel the difference.

Also get the titanium Bevel shafts, and titanium 2 speed shoe holder.

16 races? where did you get that from? 1 day races or 3 day events?

I had full ceramic bearings on all my electric cars and they did not last much longer than the regualr bearings.

Maybe I should test the Boca bearings.....send me a set over, Robert and I'll give you my opinion

Like Robert, I also clean my bearings very regularly - after two days of running at the weekend, all bearings are flushed and re-lubed. Buying ceramics and then not maintaining them is certainly a waste of money. You can only get the best out of the bearings by looking after them.

Cheers, MArk.

ITs all about the seals man. Ive a feeling you tested the ACER ones.

Utter rubbish I found them. Some of the seal was binding while other portions left huge gaps.

Boca are the best in my opinion. Stay away from Acer
