Lithium hydroxide with 12-hydroxy-stearic acid (or hydrogenated castor oil) they form the family of lithium greases very commonly used for general lubrication and bearing lubrication. 

These pumps normally use sleeve bearings lubricated with oil, grease, or even the pumped liquid (except for abrasives). 

In general, the lubricant for open or partly enclosed gears is used on a total loss basis - it is neither recirculated nor recovered. Rates of application must be minimal, both for economy and because the accumulation of used lubricant creates problems. A distinguishing feature of this category is that separate provision must be made for lubricating the bearings - by grease cups, oil bottles or mechanical lubricators. 

The hydraulic fluid continuously lubricates the components of a hydraulic system, which must, of course, be suitable for this purpose. Many ball and roller bearings are grease-packed for life, or need attention at lengthy...

Turbomolecular pumps and frequency converters are nearly maintenance-free. In the case of oil-lubricated pumps it is necessary to replace the bearing lubricant at certain intervals (between 1500 and 2500 hours in operation, depending on the type). This is not required in the case of grease-lubricated pumps (lifetime lubrication). If it should become necessary to clean the pump s turbine unit, then this can easily be done by the customer, observing the procedures described in the operating instructions.

Abstract Grease lubrication is a complex mixture of science and engineering, requires an interdisciplinary approach, and is applied to the majority of bearings worldwide. Grease can be more than a lubricant it is often expected to perform as a seal, corrosion inhibitor, shock absorber and a noise suppressant. It is a viscoelastic plastic solid, therefore, a liquid or solid, dependent upon the applied physical conditions of stress and/or temperature, with a yield value, ao- It has a coarse structure of filaments within a matrix. The suitability of flow properties of a grease for an application is best determined using a controlled stress rheometer for the frequency response of parameters such as yield, a, complex shear modulus, G phase angle, 5, and the complex viscosity, rj. ... 

Booser and Wilcock [10] viewed the function of grease in ball bearing lubrication as a controlled release of oil to the zone of contact of the balls with the races and the cage. Following this line of thought, A. E. 

Various lubricating greases are formed from the fluids by the incorporation of soaps. Greases for both low (—75 0) and high (200 C) temperature are available. Typical low-temperature uses are in small exposed motors and on the free ball bearings in transits which have to operate under arctic conditions. At temperatures above 1S0 C the alicone greases have been found to have about ten times the life of a petroleum grease in a motor.

B. Because of their spherical shape, Cgg molecules are used as nanoscale ball bearings in grease and lubricants. We can estimate the size of these ball bearings by examining C—C bond distances. Carbon-carbon bond distances...
