Why do YOYOFFICER you seem so prone to vibe?

[SCooters]

I’m confused. I’ve gotten two Yoyofficer yoyos, and they play fantastic until you take them apart enough. After you take them apart enough times, they suddenly start vibing like crazy without warning. Does anybody know why this is?

[Throwto100]

You say that like its a fact all yoyofficers are prone to vibe.

Yoyos can become vibe randomly, then become smooth when they are screwed together again.

Are you a yoyofficer expert who has tried hundreds of models? I’m not.

You make a very good point. I guess I can’t accuse all Yoyofficer yoyos of this, but of the models I have tried, they started vibing when I took them apart and put them back together enough, and no matter what I tried it wouldn’t go back to being smooth. I don’t know why on Earth this happens, and I’m wondering if anyone knows.

[Myk_Myk]

Did they have tight bearing posts when they were new, and now they are not so tight?

That might be it

I own four YYO-yoyos and all four of them have become less smooth after unscrewing and screwing them back together. They still play as good as they did when i got them, but it is for sure an annoyance! Next YYO i’ll buy i’ll for sure not open.

[JDSuperhero (Jay)]

How often are you guys unscrewing them? I’ve had my YYO Urban for a year and have had absolutely no issues with vibe, even after unscrewing it maybe half a dozen times because of especially stubborn knots. You’re not really supposed to unscrew yo-yos that often.

Most of mine got an increasing amount of vibe after opening them up for the first time.

[kadabrium (Draupnisfrœðingr)]

As far as I can remember iv never had yoyos contract additional vibe by apparent screwing alone.
That said, I have owned more than a dozen yyos and they do seem have an above average rate of coming stock with noticeable vibe to begin with.

If I had a yoyo that utilized a bearing and I couldn’t take it apart due to fear of it being ruined in ANY sort of way as a result of taking it apart…I’d toss it right in the trash

[JDSuperhero (Jay)]

I mean, I’ve never been afraid to take mine apart. My Urban is a little workhorse and definitely doesn’t have vibe. I’m a little surprised that so many people seem to have a problem, tbh

Do you own any inexpensive Chinese aluminum yoyos?

I don’t own any YYO yoyos, so I don’t know first hand that they have this issue. However, I notice many in their line are inexpensive Chinese machined aluminum yoyos.

One Drop addressed this issue once on here:

@da5id

I’m glad you raised this topic.

The agreed upon terminology is “Bearing Post”. “Bearing Seat” is the ledge that the inner race of bearing sits on and you definitely don’t want to sand that. That might seem too pedantic but it’s an important distinction. Also, do we really accept that it’s normal to have to sand a new product that you just bought? If it needs sanding, shouldn’t that be done before it’s sold?

Speaking of bearing posts and the now very common tight bearing posts, I feel it’s important to discuss this situation because it is one of the biggest differences between what we do at One Drop and what happens with many or most Chinese made yoyos. Nothing is free, so there are reasons why Chinese made yoyos cost less and the result of one of these reasons is tight bearing posts.

So why is that many Chinese made yoyos have tight bearing posts? Why do companies sell bearing removal tools? The reason is that the tolerance to make the post the correct size is incredible small. In manufacturing, the tighter the tolerance the higher the cost so to save money Chinese made yoyos are made with a looser tolerance on the bearing post. This tolerance is aimed at ending up with a tight bearing post because the result out of the box is a smooth yoyo. If the bearing post is too loose then it’s possible the yoyo vibes. Various yoyo manufacturers have been trained by the customers that vibey yoyos are completely unacceptable so if you are going to get the size wrong (and they get it wrong most of the time) they feel it’s much better to have a tight post and a smooth yoyo out of the box. The problem with this is that as soon as you take the yoyo apart (and especially if you try to remove the bearing) you begin damaging the bearing post with ultimately leads to the yoyo being vibey anyway. So they aren’t built to last in this sense. If you examine the bearing post on one of these yoyos you can usually see a black ring at the base of the post or sometimes even raw aluminum. If you sand the post as suggested above, you are likely to make the yoyo less smooth as well because it’s impossible to do it evenly - essentially by sanding it, you are damaging it.

It is possible to get lucky and get a Chinese made yoyo with a correctly sized bearing post, but in our sampling the percent that are tight is very high. This is supported by the fact that these companies sell bearing removal tools and that it has almost become acceptable as normal and okay to have the tight bearing (as YoYoexpert Garrett says “nothing to worry about”). We are also seeing people tout yoyos in the BST that have never been taken apart as a good thing.

Having made tens of thousands of yoyos in our shop we know exactly how difficult it is to get the post size right. Everyone who has made a modern yoyo has struggled with this. You literally have to hold NASA/Aerospace level tolerances AND then get lucky that the anodizer doesn’t mess it up. It is very difficult and very expensive to do it right. We would love to sell yoyos with press fit bearings and we could do it at a much lower cost because the tolerance is so much bigger. But we believe that the bearing needs to be serviceable without ruining your yoyo and we will continue to work hard to make this option available to you.

We have also noticed that import centering bearings on most of these yoyos have a rough surface on the inside diameter (the part that comes into contact with the bearing post), and that the inner race diameter is often undersized (making it even tighter). If you look at it under magnification you can see it. If you look at a One Drop 10Ball under magnification the surface is perfectly smooth. This rough surface also damages the bearing post because it’s essentially like sand paper. Depending on the tolerance matching, it’s possible one of these bearings in a One Drop can also damage the post.

Thank you to yoyoexpert and to all who continue to support us so we can continue to provide this alternative option.

[Diagnosed-Ghost]

I’m sorry to hear that. I have had an entirely different experience with yoyofficer. My urban, shift, and rave are as smooth as they come even after many many unscrews.

After experiencing the instant vibe after one unscrew with other companies I planned to purchase more yoyofficer… But I think I might buy a one drop instead.

[yoyodoc]

I have a question for you guys.

When you say, ‘I took my yoyo apart’… do you mean you just unscrewed the halves?

Or did you also take out the bearing?

And if you took out the bearing and you didnt take out the bearing with the ‘proper tool’; that could be your problem.

I dont know what you did or what you ‘do’. But lets just say your favorite bearing removal tool is a pair of pliers. <then that would explain plenty right there.

If you distort the yoyo halves in any way while ‘removing’ the bearing; then nothing is going to get better.

And your yoyo wont play like it did before.

[morgothaod]

Are yoyos really not supposed to be unscrewed?

If they were not to be unscrewed they’d be welded shut.

Totally agree that distorting the bearing post by using the wrong tool could cause problems, but even with a proper tool you have to rock it off the post. Also, if what David is saying is true, then just taking the yoyo apart multiple times could wear down the bearing post on one side, possibly inducing vibe.

I JUST unscrewed the halves. Never removed or tampered with the bearings that came with my four YYO’s

@jhb8426

No, no they would not. Probably some kind of press fit or some very though loctite.

[TravWells]

I have take my Vector apart or unscrewed it alot of times and never had any viberation issues.

[Cannon (WH0TH3MAN (for Glen's reference))]

It sounds like many of you would be horrified to watch me yoyo. If I get a knot I place my palm on one half of the yoyo, spin it quick, pop one half in the air and catch it, tear the string out, then throw the whole thing back together and keep going. I take my edc apart probably 3 times a day minimum.
