Materials

 

Typical porous material is carbon graphite, carbon, or silicon carbide, familiar materials with proven track records. Due to construction methods, a porous material bearing in a metal holder, will operate up to about 300 degrees Fahrenheit.  Input pressure to the porous material is typically 60-100 psi, but can be higher, based on the specific need (e.g., for carrying higher loads).  These materials have high heat capability, since they are typically sintered when manufactured; they can typically resist oxidation to at least 600 C without melting (like babbitt).

 

The bearing below on the right is a monolithic porous media bearing (carbon graphite), and as seen, there is not a metal holder in this case.  In situations where such a bearing can be used, the temperature range can be higher, although loading must be taken into account.

 

 

 

 

 

The porous material for Bently Bearings can also be made in ceramic matrix composites.  Custom materials can be made to accommodate higher temperatures, and more extreme conditions.  

 

Call us to discuss your specific application, and Bently Bearings will provide the correct material option for your need.

Our CMC materials are similar to those used

for race car braking applications, and can be 

used for high temperature applications.
