💡 Why are hybrid ceramic mini bearings so popular in high-speed setups?
Ceramic balls reduce friction and heat buildup, giving smoother performance and longer life.
Higher RPM capability
Lower rolling resistance
Better wear and temperature stability

Perfect pick when you want a tiny bearing that runs fast, cool, and clean.
