This is a term used to indicate how good the product is to prevent corrosion from taking place in an application, which is an important aspect when applications operate in wet or humid conditions. Our method of evaluating this property is typically the Emcor test, which is a dynamic bearing test performed in presence of water that shows how well the grease can protect the bearing surfaces during a defined test cycle.
This is a term used to indicate the ability of the grease to protect the application from shock loads. Shock loads are short spikes of high load that may take place in an application that risk to damage the application surfaces. Some examples here are forces created when large rocks are handled by an excavator or when a truck passes a bump on the road.
Heavy loads, and high loads, are continuous high loads that is affecting an application. These loads depend on both the size of the application and the load it is carrying.
