High Temperature Ceramic Bearings

High-temperature applications demand bearings that can withstand extreme heat without sacrificing performance, durability or reliability.At Lily bearings, we carry inch and metric size high-temperature bearings that maintain exceptional performance at temperatures to 2372 F (degrees fahrenheit) = 1300 C (degrees Celsius).

Our high-temperature bearings are manufactured from heat-stabilized stainless steels and ceramic materials. We also improve the high-temperature performance of our bearings through features such as:

Perfluorinated polyether (PFPE) and other high-temperature lubricants

“Loose” internal clearances to accommodate larger coefficients of expansion
