Chrome Yoyo Bearings
It has long been the industry standard for Yoyo enthusiasts the world over. These bearings have chrome steel races, balls, retainers and shields.
Stainless Steel Yoyo Bearings
In an attempt to improve the performance of these bearings, are specially designed for competitive yoyo enthusiasts. Competitive players sought out high ABEC bearings made of high-grade materials such as stainless steel. The higher the ABEC rating, the lower the friction and smoother and faster roll. ABEC ratings are given in odd numbers only 1,3,5,7 and 9.
Ceramic ball yoyo bearings
Today, ceramic bearings are the hottest thing in yoyo technology. They are lighter, smoother, stiffer, harder, and corrosion resistant. These characteristics allow for a wide range of performance enhancements in bearings. Ceramic dissipates heat quickly, reducing friction and wear while maintaining a precise smooth surface. Today’s leading-edge ceramics are made with Silicon Nitride (Si3N4) and have characteristics similar to the heat-absorbing, highly resilient tiles on the Space Shuttle. Yoyo Ceramic Bearings are specially designed for competitive Yoyo enthusiasts.
