Which bearings (available here at YoYoExpert) are most susceptible to rust?
I want to purchase a few bearings that are most likely to rust, but I don’t know which ones will rust the most. If you have experience with all the bearings available here, your help is appreciated. :slight_smile:

The ordinary YoYoJam Size C bearings. Not the “Speed” bearings.

Out of curiosity, what are you planning on doing with rusted bearings?

For me, the only ones that rust in general are the regular YYJ bearings.

And…yeah, I’m kinda courious too.

I plan on doing a science project on the different amounts of oxidization with bearings in different environments. Thanks guys!

Ive had my first ever stock YYJ rust so badly it doesnt fit on the bearing seat anymore. :confused:
