Ceramic Balls vs. Steel Balls
Ceramic balls offer advantages such as being lightweight, lower friction resistance, high temperature resistance, higher rigidity, higher hardness, smoother surface, and higher corrosion resistance. Ceramic balls include materials such as:
Ceramic balls also require less lubrication than steel balls
Ceramic balls and bearings are used in bicycles, tools, check valves, automotive parts, gauges and many other machine components.
Ceramic balls are being used more frequently in competitive cycling. Silicon Nitride balls for bikes are much less heavy than the steel ball counterpart and have an excellent smooth surface for better rolling and spinning.
