High Temperature Replacement for C95400
High Temperature Replacement for C95400
(OP)
We are currently investigating a replacement bushing material for C95400 aluma bronze. Our application operating temperatures are now reaching 1300° which is far above the maximum operating temperature of the C95400.
For the application, the bushing is pressed into a cast iron housing. A 303 stainless shaft travels through the bushing, there is very little load on the shaft and the shaft only rotates 90° back an forth about 5 times a minute.
We were considering using Nitronic 60 for its high temperature service properties as well as its anti galling properties.
Any other ideas are appreciated.

I would try to use a CI bushing from ASB with a high temperature lubricant from ZYP. Do not use graphite or moly as your temperature is too high.

What is your operating environment?
Is the 1300F the max or is it a continuous temperature?

The assembly sits in the exhaust of a diesel engine. So you would have plenty of carbon soot, moisture, CO... expelled from the engine.
