In this chapter, the composition and properties of lubricating greases will be described. The definition of grease is diverse. Grease is defined by the National Lubricating Grease Institute (NLGI) [450] and the American Society for Testing and Materials in ASTM D288 [195] as ‘a solid to semi-fluid product or dispersion of a thickening agent in a liquid lubricant. ˇ epina [560] defines Other ingredients imparting special properties may also be included’. Stˇ grease as ‘lubricating greases are colloidal systems (dispersions), mostly gels, rarely sols, in which the dispersive (continuous) phase is formed of lubricating oil and the dispersed phase (thickener) is an anisotropic solid which penetrates the liquid phase so that the gel produced acquires properties characteristic of the plastic (solid) state’.

Booster and Wilcock [97]). This was also clearly found in the spherical roller bearings test from Wilstr¨om and H¨oglund [611, 612] where both grease and base oil were used and where equal friction torque was measured. Mas and Magnin [402] investigated grease before and after running in tapered roller bearings and found an increased viscosity of the grease and reduced oil content under the cages. This implies that grease bleeding occurs from grease located under the cage bar. However, they also show by means of SEM the destruction of fibres in the raceway, confirming once more Cann et al.

They are hydrophobic, repelling water and protecting metal components from rust and corrosion. Mineral oils are compatible with a wide range of grease thickener and additive systems [471, 480]. 2 27 API (American Petroleum Institute) Group Base Oil Classification [471, 507]. 01 – 80–120 80–120 >120 >120 – typically contain hydrocarbons with 25 or more carbon atoms. 154 nm, such a molecule would be approximately 3 nm long. 17 nm. 2 nm. Typical EHL films are in the order of 500 nm, which means that a maximum of about 2500 molecules would fit over the height of such a film.
