Grease - Temperature Limits
Temperature limits for grease - a combination of oil and thickener.
Grease is a combination of mineral or synthetic oil and thickener - also called soap. Rust and oxidation inhibitors are also often added.
- Oil content ranges 70 - 97% - commonly about 80%
The temperature limit for a grease is limited by the oil and thickener used.
| Grease Thickener | Temperature Limits | |
|---|---|---|
| (oF) | (oC) | |
| Aluminum | 180 | 82 |
| Barium | 225 | 107 |
| Calcium | 170 | 77 |
| Lithium | 300 | 149 |
| Sodium | 250 | 121 |
