Lubricants | Special Issue : Lubricating Greas

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. This may be one of the reasons why, up to now, not much attention has been paid to innovation and research on ...

Grease Additives - Lubriz

The incorporation of polymers can build base oil viscosity, and can provide enhanced film strength, tack, water resistance and reduced oil separation to the finished grease. Lubrizol offers a wide range of liquid, solid and functionalized polymers to help you formulate greases based on your specific requirements.

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 .

Liu et al. [ 9 ] proposed a two-phase hydrodynamic film model for the thin films formed by water in oil emulsions, in line contacts, by taking into account the size of the dispersed water droplets. In an earlier paper, the authors [ 1 ] studied the impact of water on the rheology of lubricating greases.

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.

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.
