ZrO2 Ceramic Bearings Description
ZrO2 Ceramic Bearings can be used up to 400℃. The maximum speed should be decreased as the temperature increases above ambient, particularly if the bearings are unlubricated. Bearings with a PEEK cage are rated up to 250℃ due to the lower maximum temperature of the cage material. It may be preferable to use a looser radial play at high temperatures, particularly if the inner ring temperature is likely to be greater than the outer ring temperature as this will reduce the radial play of the bearing. Our ZrO2 bearings are supplied with a looser C3 radial play as standard.

ZrO2 Ceramic Bearings Applications
ZrO2 ceramic bearings find versatile applications due to their lightweight, high hardness, and low friction coefficient. Widely employed in high-speed equipment like power tools and motors, these bearings are also crucial in medical instruments for their biocompatibility and corrosion resistance. In the food processing industry, their non-toxic, tasteless, and corrosion-resistant properties make them ideal for equipment. Additionally, ZrO2 bearings are chosen for their corrosion resistance in chemical industries and their suitability for high-temperature, high-speed environments in aerospace applications.
