Lubricating greases work under extreme operating and stress conditions that can severely affect their structure, behavior and performance. Anticipating this is crucial for the proper selection of grease.

Rheology is the science that studies how fluids move in different circumstances and the rheometer is the tool.

Studying rheology we analyze the effort-deformation relationship of greases and fluids.

The flow and deformation behaviors depend mainly on three factors:

🔸 Internal structure of materials
🔸 External forces acting on materials
🔸 Temperature

We study the rheological curves of lubricating greases by varying these three factors and we are able to predict what the behavior of the grease will be in the real application and, therefore, select the optimal grease for each service.
