💡 What’s the advantage of ceramic ball bearings over steel?
Ceramic ball bearings are lighter, harder, and smoother than steel, resulting in lower friction, less heat, and longer lifespan - ideal for high-speed and precision environments like electric motors, drones, and medical devices.
I bought these for the bottom bracket on my bicycle to replace some standard bearings which became rusted and contaminated in less than a year. Hopefully, these ceramic bearings with stainless steel cages and races will resist corrosion and can be periodically cleaned to remove dirt. They cost far less than similar bearings sold by bicycle component makers. I was initially sent the wrong bearings, but I called the company and was sent the correct bearings pretty promptly at no extra charge.
