The Xtreme 6000 ZrO2 Series of Full Ceramic Radial Bearings from CeramicSpeed are designed to provide levels of performance in extreme environments beyond the capabilities of steel and even hybrid bearings. The complementing components of these bearings were carefully selected to provide the highest levels of performance in high temperatures, and adverse environments such as: Submerged in water, high pressure steam, chemicals, and caustic fluids.

The outer and inner races of these bearings are meticulously crafted from zirconium dioxide (ZrO2). Zirconium dioxide is exceptionally tough and has heat expansion properties closely matching those of steel for easy integration into new or existing applications.

Silicon nitride (Si3N4) was selected for the bearing balls as it can achieve the highest possible smoothness and roundness.  The standard bearing cages are PTFE. Optional PEEK (Polyether ether ketone a thermoplastic polymer), cages with a high melting point can be specified as well as PTFE or PEEK shields. The combination of zirconium dioxide races and silicon nitride balls create a bearing with a very low coefficient of friction that are able to operate with very little or no lubrication.

Xtreme 600 ZrO2 bearings in comparison to steel are lighter, nonconductive and nonmagnetic, with a much lower coefficient of friction than steel or hybrid bearings, and Silicon nitride (Si3N4) balls will not spall.   Applications include medical, pharmaceutical, aerospace, maritime, industrial, food, dairy and beverage.
