💡 Why choose hybrid ceramic bearings over full steel for high-speed use?
They cut friction and heat in fast-spinning applications.

• Ceramic balls are lighter and run smoother than steel

• Lower heat buildup = longer life at higher RPMs

• Open style allows for custom oil or air-lube setups

• Great for CNC spindles, brushless motors, and hobby racing
