The life of a yo-yo is measured in bearings. A long time ago, ball bearings were a secret weapon only found on top-end yo-yos, but nowadays over 99% of yo-yos made are outfitted with a ball bearing of some sort. And it's gotten to the point where ball bearings are designed and produced specifically for use with yo-yos.

Different shapes and sizes were developed to complement the different styles of play out there, but no style has seen greater advances than string tricks (1A). The most popular development in 1A bearings was the advent of the concave bearing, made popular by Dif-e-Yo's Konkave bearings. Nowadays it's not hard to find a yo-yo that comes with one of these high-end bearings standard.

They're assembled under the watchful eye of master craftsman, in a completely dust-free clean room to ensure no foreign particles make it into the bearings.

*Over time, the gold plating will slowly wear off. This part is machined to high precision, so caution is needed to prevent a bearing lock from freezing it up. The bearing plays best right out of the box, bearing lube is not necessary (and the bearing is so precisely machined, there's no place for oil to enter the bearing.
