Living in the hot life! 1,000ºF is what this little bearing handle. That is pretty hot if you ask me. http://www.vxb.com/page/bearings/PROD/HighTemperatureBearings/Kit18121 This bearing is made of Silicon Nitride races and ball bearings. Ceramic is non magnetic, non conductive, and produces the least amount of friction. You will notice, this bearing has no cage and that allows for the ball bearings to expand in the heat. The bearing needs to be used in an application with no vibration, light load on the bearing, and no heavy impact as the bearing is brittle. The featured bearing measures 8mm x 22mm x 7mm, 608 Full Compliment Ceramic High Temperature Bearing.
Highest Temperature: 1000 (degrees Fahrenheit) = 537.78 (degrees Celsius)
