Understanding Grease Compatibility

Grease compatibility refers to how different types of greases interact when mixed together. It can have a significant impact on the performance and reliability of the lubrication system.

Types Of Grease Compatibility

Greases can be categorized into three main types based on their compatibility:

  • Compatible: Properties of the mixture are similar to individual greases.
  • Incompatible: Properties of the mixture are significantly different.
  • Borderline: Properties may or may not be acceptable depending on the application.

Effects of Incompatible Grease

When incompatible greases are mixed, it can lead to various issues such as:

  • Softening or hardening of the lubricant
  • Overheating and excessive wear
  • Bearing failure
  • Bleeding or separation of thickener and liquid

Greases That Should Not be Mixed

Some greases are more incompatible than others. For instance, aluminum complex, calcium complex, clay, and polyurea-thickened greases should not be mixed due to the risk of substantial softening or hardening.

Expert Recommendations

Leading grease manufacturers like Shell, Mobil, and Texaco advise against mixing greases. The consensus is clear: avoid mixing greases to prevent performance issues and potential damage to machinery.
