Modern advancements in lubricating grease technology Modern advancements in lubricating grease technology Lugt, Piet M. 2016-05-01 00:00:00 Grease is one of the major bearing components and the performance of a grease lubricated bearing is strongly determined by the performance of the grease. This paper describes how grease knowledge is linked to improved rolling bearing performance.

Impact of Water on the Rheology of Lubricating Greases ....

ABSTRACTThe operational life of bearings is often determined by the performance of the lubricating grease. The consistency of the grease prevents it from leaking out of the bearing and provides good sealing properties. The possible ingress of water into the bearing will have a considerable impact not only on this consistency but also on the lubricating ability of the grease.

Impact of Water on EHL Film Thickness of Lubricating ....

In an earlier paper, the authors [] studied the impact of water on the rheology of lubricating greases.The model greases represented the most commonly used thickener–oil systems that are used in rolling bearings.

Impact of Water on EHL Film Thickness of Lubricating ....

Although grease can absorb large quantities of water, separation occurs due to pressure and shear, leading to free water. This does not have an impact on the film thickness under fully flooded conditions. However, water does have an effect on the film thickness under starved conditions where the differences are related to the change in oil bleed.

Lubricants | Special Issue : Lubricating Greases 20...

This Special Issue came as the natural consequence of the great success of the previous Special Issue “Lubricating Greases”. Although lubricating greases are widely used in many specific applications, their market only constitutes a very low percent of the total amount of lubricants processed in the world.

Influence of Soap Concentration and Oil Viscosity on the ....

The effects that both soap concentration and base oil viscosity exert on the rheology of lubricating greases and its relationship with grease microstructure are discussed in this work. With this aim, different lubricating grease formulations were manufactured by modifying the concentration of lithium 12-hydroxystearate and the viscosity of the base oil, according to an RSM statistical design.

Petroleum Lubricating Oil and Grease Manufacturing ....

Lubricating oil, sometimes simply called lubricant/lube, is a class of oils used to reduce the friction, heat, and wear between mechanical components that are in contact with each other. Lubricating oil is used in motorized vehicles, where it is known specifically as motor oil and transmission fluid.
