Product Description
hybrid ceramic ball bearing 689 689-2rs with ZrO2/Si3N4 balls
Ceramic bearings have the normal steel balls replaced by white ceramic balls. The ceramic balls
are made of solid silicon nitride. Ceramic silicon nitride balls are called ceramic but have nothing
in common with household dish ceramics. They are called ceramic because it's easier calling them
ceramic then silicon nitride. The ceramic silicon nitride ball is by far, smoother, harder, lighter and
stronger than one made off steel.
