Dnano Bearings
 

If any one is interested in saving alot of money. Boca bearings sell 10 packs for 8.99 and they have bearings that fit Dnano's. I stumbled apon this by ordering bearings for my other scale cars so I would like to pass this ifo on. 24 dollars is a bit steep for 6 tiny bearings. You can outfit 2 cars for less than the price of one bearing set and have more to spare. Just go to their site click on search and enter the bearing size than click rc 10 pack. I hope i'm allowed to post stuff like this.

i can understand trying to save a few dollars here & there but... i think most consumers like for purchasing to be as easy as possible. give it to me in a package where i don't have to find dimensions or even THINK to get it right and its more apt to find buyers. 2nd, i think guys in the RC hobby kinda like stuff that's tried, true and pretty much guaranteed to give you the results you want cuz though money is valuable in a sense, so is TIME and EFFORT. what happens when you get ONE size wrong? what happens when the performance isn't the best? then you've wasted the money you thought you would be saving by going cheap when it would've been right the first time by going for something already known to be of high quality and to the EXACT specs required?

do your thing, enjoy the hobby... but really, going cheap isn't always the best answer and expensive doesn't mean 'bad'. besides, 'expensive' is a relative term :D

2. size(s) for dnano bearing(s)

qon is very much correct in that the average person just wants to buy a single package that has it all. dedicated racers on the other hand will eat this stuff up as they are already typically very comfortable purchasing ala cart and know what they are looking for.

bearings, like anything else coming in varrying degrees of quality and materials. you can buy $1 bearing or a $10 bearing. it all depend on personal value and desired performace from said bearing.

what would be nice to see is a good comparison of the various bearings available for the dnano in both cost, quality and general opinion.

I understand your point but Boca here in the USA is one of many companies that the pro's use. Not only do the cater to RC but everything imaginable that requires a bearing. Very high quality and very reputable. Sure OEM parts are great. I use them too. Bearings on the other hand are bearings whether they are stainless or ceramic cheap or expensive you will replace them eventually. It is next to impossible to compare a 4mm bearing to another other than when one is dirty or gritty feeling.. They are just too small. I am just trying to inform others that are maybe on a budget. Just my thoughts.

Here are some links.

Wheel bearing size is: OD 4 W 1.2 ID 1.5
Rear is: OD 6 W 2.5 ID 2

Hope this helps. I understand buying 1 pack of complete bearings, but I would be much happier recieving a tube full of them!

i understand the point very well and will be looking into this myself for both my mini-z's and dnano's. i am th type that would buy in bulk simply because i have so many rc's it's more economical to do so. anyone have a link to the precise dnano sized options?

not all bearings are the same at all and any rc guy will tell you that and any competitive racer will argue with you on that one. you can buy the cheapo's and you can but the full on ceramics and there is a huge price difference. there are plenty of the budget options for the mini-z for example and there are a couple shops that cater to the competitive racers whom offer the expensive lines.

i fully support your quest to share information. i've been waiting for someone to do this so i didn't have to invest the time to do so. i just never seem to find the time. i do not support the idea that you must buy the best or nothing at all. buy what your level of interest and skill will support.

Agreed. In the post above are the dimensions for the Dnano bearings.

those sizes do not turn up any search results.

...............

Try those sizes. I entered them in wrong. Sorry about that.

Cheapest I see is $5.95 each, which is not cheap at all. No 4 packs available for either bearing.

You need to scroll down because there are more than one type of bearing. You will see RC ten packs for 8.99

i was looking in the kyosho site the actual sizes as per kyosho are

rear bearings 2x6x2.5mm

and front bearings are 1.5x4x1.2mm

and that's why people normally don't mind paying more cuz -in the end- by trying to go 'cheap' you end up wasting money on wrong sizes, shipping, etc and costs that would likely add up to the same amount you would've spent by just getting what you KNEW was what you needed in the first place (jmho).

hey guys on the boca bearing set issue as far as price savings there are non look at what the kits costs its actually more expensive than the kyosho kits

KYOSHO RC CAR DNANO 1/43 SCALE #25-555 7 $31.95
KYOSHO RC CAR DNANO 1/43 SCALE #25-555C-YZ 7 $49.95

info obtained right from the boca site hope this helps

Buying bearings individually yes, but you are not looking in the right place. There are 10 packs for 8.99 thats 10 bearings for 8.99. So for the fronts and rears total would be less than 20 bucks for 20 bearings.

Can you post a dirtect link I loolked all over but couldn't find it ....thanks

When you enter in the bearing size it takes you to a selection page to choose which bearing you want. If you scroll down you will see RC 10 pack for 8.99. Click on it then you can add it to your cart. You will need to do this for both bearing sizes, but I will try to get the link for ya.

The link doesn't connect to the bearing just the seach function. You'll find it. After you search for the size it's the second one down.

hey i still cant find it can you post the part numbers so i can search for them that way thanks

Thanks for sharing bro! I got the front bearings fine in the search...can you double check my part numbers?

Front bearings with OD: 4 W: 1.2 ID: 1.5
part #99MR681-XC-X10

Rear bearings i couldn't find the 10 pack? When i input OD: 6 W: 2.5 ID: 1.5

Two items appeared: Part# MR601-X and SMR601-X

There was no RC 10 pack option? Can you confirm the rear bearings please?

I have a few sets of Kyosho bearings so maybe I'm going to test these back to back?

Thanks again!

-Ray

Could the Rear bearing dimensions be this?

OD: 6 W: 2.5 ID: 3

There seems to be 2 types of bearings for the Dnanos...the expensive ones that another poster listed were for Ceramic and the bearings the Original Poster mentions is the "econo" bearings.

I wonder which is more comparable to Kyosho ball bearings?

-Ray

Ray the sizes that I listed are correct the rear is 6x2.5x2 . They might be out of stock in those. I would say that the Kyosho bearings are economy bearings definetly not ceramic.

No matter what happens get the ceramic ones. My car just rolls off the table with the pinion gear out if the table is even slightly tilted. Other three cars with regular bearings don't do that. Only my Corvette with ceramic bearings will. I am a believer in ceramic bearings. they are worth the price.

Thanks :)

-Ray

Ray they have the bearings in stock. You entered the wrong size 1.5 when it should be 2

Ceramic bearings in a Dnano is a waste of money. Even if your a hardcore racer the difference is pretty much nothing and if you just running your car on your private track why even bother at all. Any car will roll with no motor in it. Thats not a justifier to spend all that $$$, but this is just my opinion I mean no foul.

i'm a hardcore racer... the ceramic makes a huge difference in dnano. i just think you're on a low budget and can't afford the best option parts for your car. there's nothing wrong with that, if your pockets aint deep, u gotta go cheap.... but don't expect others to follow your lead when quite honestly, if you're willing to spend the money on what 'hardcore racers' have tested and proved, then you don't have to go thru headaches to search for 'bargains' that ultimately won't give you top performance.

i'm not speculating... i've been racing, tuning, testing dnano for ~18 months now almost daily. its a small car, but all the little parts make a huge difference collectively - take my word for it. ;)

re: all kyosho bearings are NOT ceramic, XP rear bearings are ceramic, front are steel.

You have the right to your opinion, but I would say half the people that own Dnano's run them at home by themselves. Yes you have access to everything because your a shop owner and your testing everything you can get your hands on and you want to sell products. As far as my budget is concerened I can afford to buy anything I want, but why spend the money for nothing just to say I have this on my car. This is just my opinion. This is mainly in part why Dnano's are not popular in the US. Kyosho produces a product that is very limited and yet very expensive for what it is. The funny thing is you spend top dollar on those ceramic bearings and they are sealed so you cannot even clean them properly. Go figure...

ummm... i think YOU were the one that made a reference to 'hardcore racers' so, i just gave you a hardcore racer's opinion. if you're just running it at home, and don't care about performance, use the Kyosho (or ABEC35) bearings... they come in an easy to buy set and you don't waste money hoping you got the right thing.

if you feel that's what installing ceramic does for you, you're right, that's your opinion but the FACT is that ceramic is a better material for the application than steel. if you're going to give advice or recommendations to the guys enjoying this forum, just know what you're talking about. that's all anyone expects... JMHO.

would you say an iphone is too expensive? its JUST a phone, right? if you don't understand what went into the technology or why its ground breaking, then that's your shortcoming, not others who do appreciate it. why be negative about it?

isn't that the point of a 'sealed' anything? not having to clean it? :D

I'm not here to start a flame war, but to suggest an alternitave that in my mind is a better deal considering my 25 years experience in RC and tens of thousands of dollars later. Like I stated this is my opinion.

If this is what you believe then I'm ok with it.

wow lets not get too carried away guys :P

This is after all just RC cars...not even real racing lol.

But seriously, even real racing isn't about dumping every $ possible to be considered "hardcore racers"...

as far as i know, Subaru and Suzuki are out of WRC, Porsche and Audi are out of ALMS, Honda out of F1, and I believe i read a while back that Motorcycle racing isn't doing too well either (getting costly for these manufacturers)...

So racing isn't necessarily just about having deep pockets...as long as the cars are setup similarly, there can still be very competitive racing :D

I believe it would be just as fun to run box stock dnanos in a "stock" class...would you guys agree? Its about fun, lets not forget that :)

Thanks Tsal for doing the work for us and finding out the size of bearings we need :) I personally like doing the tests myself and find that part fun...I'll be ordering the bearings and comparing Kyosho, Boca economy, boca ceramic :)

-Ray

forums are all about discussion and debate so to me, this is normal banter between guys with differing opinions, interested in the same hobby. i'm cool ;)

by 'hardcore racers' i assumed this meant people who race often - which i do. i don't think one needs deep pockets at all, i just think what's expensive to one person may not be to another.

i think most 'RCers' like to tinker and try different things and again, if you feel like some of the items that have proven 'best' by 'hardcore racers' isn't for you, just don't get them BUT... because they are 'expensive' doesn't make them 'bad' or 'not worth it'. it IS all about fun... post your results on your findings, Ray... we're all interested and appreciate your sharing and that includes TSal for researching and offering an alternative. :D

there are countless threads on the warrant of cheap or expensive ball bearings. this is well documented throughout all scales of rc. if you want the best, you pay for it.

a quick search on mini-zracer gives you this.

and yes, even at this scale the difference in quality bearings is real.

I'm trying to order the bearings today but i'm so confused.

I know the front econo 10 pack is 4 x 1.2 x 1.5

the rear econo is 6 x 2.5 x 2

but when I'm looking at the ceramic bearings to purchase, i look at the bearings itemized in the kit and the dimensions are different? The $50 ceramic Dnano kits say the fronts are 4 x 1.2 x 1.5 which is the same as your info

However, the ceramic kit states the rear dimensions are 6 x 2.5 x 3?

I'll just purchase and hope that extra 1mm doesn't make a difference for the rear Inner Diameter (hopefully it doesn't have too much play with the diff shaft).

I'll keep you guys updated...but i don't really know how to test it with empirical data? Any suggestions? I can go by feeling but that isn't accurate...testing lap times are possible too but i'm not consistent enough and my track is too small (best lap time with the track upstairs is 2.87 seconds...lol).

I'm going to purchase and keep you guys updated if I remember to :P

-Ray

dnano bearings sizes are very specific... if the rear bearings are too wide they'll 'stick out' and rub with the wheel hub. i'm guess you're just into testing and aren't necessarily doing this for performance? it was seem strange to spend 50USD when the XP-Ceramic bearings FULL SET is ~30USD

Just like Qon says bearing sizes are very specific. I'm sure you can find different brands like XP or others to test that are cheaper in price. Good luck keep us posted.

Well, I purchased and I'll let you guys know when I get them in...I was really confused since the size you (Tsal) mentioned and the ceramic set Boca listed were different dimensions for the rear but I ordered anyways :P The dimension of the rear that was different was the ID (2mm vs. 3mm) so it'll fit fine except there may be a little free play where the diff shaft meets the bearings?

Well, I was just hasty since you (Tsal) posted this and I'm sure XP is something Qon can test (if he hasn't already) and comment on the difference between XP and Kyosho. Qon, is the XP ceramic vs. Kyosho bearings night and day difference?

Yea, I wasn't really interested in getting new bearings since my kyohso are good enough...but I'm curious if a bearing company that specializes in bearings are any better (only one way to find out). Kyosho and XP I'm assuming don't manufacture/specialize in bearings solely, so my curiosity is tempting me to try these out to see if a company specializing in bearings are any better.

So i ordered the econo 10 pack for front and rear, a set of ceramic bearings for the Dnano, and 2 sets for my mini z. I'll keep you guys updated but i have no idea how to test (if you got suggestions, let me know) the bearings.

On a side note...i have (between my fiancee and I) 6 sets of PN racing mini z bearings and they are very inconsistent (some are good, some are not, some have a lot of slop, some don't). So maybe Boca bearings will be more consistent? If not I know the Reflex bearings are good and I'll try those next.

there's rarely a night & day difference between available optional parts (well... the kyosho/xp diff and atomic diff...but thats a long story). the car and its performance are a sum of its parts. if you have one car with all the shoddy option parts and you have the same car with all the best available, its quite likely you can see a performance difference but just ONE of the parts? no... probably not.

like i've mentioned, i have all the sample option parts from lightweight wheel shafts to racing wheels - 95% aftermarket optional parts on my mazda and no other car in our club is close to the performance of that thing. if kyosho's parts were more easily accessible and more affordable, i'd probably be partial to their stuff but exceptional aftermarket options pulled me away from 'brand loyalty'.
