I don’t know the difference.

And platinum/silver over gold I’ve heard.

I had some of the gold CTs and KKs from NSK and the gold wore off. The flakes seized the bearings. I originally sold the 543s with gold NSK KKs and it happened to them, so I sent out Plat DS bearings to everyone who bought one it was that bad.


Thanks for the response.

I have a gold NSK(which I love), I just don’t know how the YYF is different. I’ve heard about the flakes too.

The YYF NSK bearings are machined by NSK, so they are exactly the same as any other NSK bearing, just available in the YoYoFactory Center Trac shape.

I have a couple platinum ones that I use regularly and haven’t noticed any issues. I have a Gold NSK concave in my Parlay that I use regularly too. It has faded, which probably means it flaked off :man_shrugging:, but it hasn’t caused any seizing at all.

YYF license the patented CT shape to NSK.

My personal experience with the gold is it wears but doesn’t flake on NSK but the fake gold bearings flake. I have not tested every run to confirm this but early ones didn’t flake.

All bearings can fail from impact and debris. It’s hard for me as a player to invest $$$ in bearings knowing that I’d the case. I’d rather be able to throw a bearing away than deal with significant maintainance to try save an investment.


Notice; I removed the primary content from this response because although I felt the information was useful. My response had little to do with directly answering the OP’s question.


Thanks Garrett.

I bought it to treat myself and my yoyo. I had the money, what the hell, right? :grinning:

I pretty much just use one yoyo anyway.

Thanks Ben.

I deleted my post because after reading your topic/question… it was quite obvious that you didn’t ask for a lecture on gold/non gold bearings. So I was just derailing your topic.

My Dad dropped dead a few days ago and I guess I just haven’t been paying attention.

I didn’t take offence. Really sorry about your Dad.
