I have replaced the bearing on my yoyo quite a few times, probably more than I should. I have seemed to notice that my bearing always slows down significantly when I apple YYJ Thin Lube. Any helpful advice of general knowledge of bearing could help. Thanks guys. ---

Lubing a bearing slows it down. Lube lightly if at all. I prefer a light lube myself. ---

The Lube creates additional friction in the Bearing, am I right? Its like Binding the Bearing without Binding the Bearing at all, in a sense. Like he said, easy does it… It works if you work it. ---

If you put a drop of lube onto a sewing needle it makes a half drop of lube on the needle which is just the right amount to put in ---

Use lighter fluid or mineral spirits to clean the lube up. A bearing will last for years if proper care it taken. I personally don’t lube, or lube just very little. ---

Could I use isopropyl alcohol to clean a bearing instead of lighter fluid or will that ruin it? ---

Isopropyl alcohol is fine. Just make sure to dry the bearing thoroughly as it contains a lot of water unless you get the 95% pure stuff. ---

So my bearing makes a loud noise when I toss my yoyo. Should I get a new one? Or what should I do. It makes this loud whistle like noise. ---

Is this after you cleaned it? Did you lightly lube it after cleaning it? If not that is why it makes noise - clean, unlubed bearings make noise as you described. Sometimes even a lightly lubed bearing will make noise. ---

Yes, this is after cleaning it. I put a very small dab of lube on there and its now quiter, but it still has a very low hum to it. I used a small sewing needle and put just a drip on the needle, than on the bearing. Than spinned it on a pencil to work it thru. I was also wondering if anyone could tell me if id benefit from a center trac bearing or konkave. What’s the difference in type x size c and the reg size c bearing? ---

For noise, CT and KK aren’t “inherently” quieter than other bearings. I do find lubed KKs can be pretty quiet most of the time. CT have a characteristic noise that comes with the territory that some people define as “the sound of modern yoyos” so not necessarily a “bad” noise. Still, you should try one! KK is my preference between the two. There’s only one size of “C” bearing that’s considered the full size for unresponsive play. It will measure 1/4" x 1/2" x 3/16" (6.35 x 12.7 x 4.7498mm). If the width is half of that, it’s a half-width bearing intended to be used in yoyos that support them for responsive play setups. Anything else is just a fancy name for the profile or materials. Not sure what “type x” would be referring to or where you’re seeing it. ---

If you go to shop, than to accessories. Than click on bearing. Than center trac bearings. Click on the choice of size. And you’ll see it say type X. I was just curious. I thank you for your information. ---

I thank you for your information. Type X on the CTs means it’s a 10 ball (X=10), also referred to as the CTX. The regular CTs are 8 ball. ---

In terms of cost:performance , CTX is my go to. For $6 more, you can get my favorite bearing, the Terrapin X Delta Ceramic. I am not a fan of flat bearings anymore now that I am skilled enough to tell the difference when I’m playing (not saying much) ---

Ironically, then you’ll reach the NEXT plateau where the profile doesn’t matter much at all because you’ll be skilled enough to not care. Haha! I’m not there yet. I also prefer profiled bearings. ---

Dang, well if you’re not there, I’ll probably still be on profiled bearings when the next great thing comes along ;D
