Pumpability is a very strong characteristic for this type of grease. Lithium grease has excellent resistance to water and breakdown, or softening, by working. Can be used with occasional temperatures up to 300☏. Has very good water tolerance.Ī multi-purpose type grease with a buttery texture and dropping point above 350☏. Higher temperatures may alter the grease structure. Calcium grease must be used in a lower temperature environment, since they are limited to approximately 150☏. Manufactured by using hydrated lime and a fatty material. Used today largely because they are moderately priced. Has good water resistance, low temperature pumpability and extremely high temperature applications where a non-melting grease is required, the clay structure can aid in setting up a self-forming oil seal where bearing seals are impossible to maintain such as in wheel bearings on high temperature kiln cars.Īmong one of the first types of grease manufactured. This type of product is often called a No-Melt grease. Not very compatible with other greases, since the electrical charge may be destroyed and soften the grease beyond performance limits.
Dexture axel bearings Activator#
Frequently used in lubricating food machinery.īentonite clay is treated with a polar activator that will give an electrical charge to the clay particles, thus aligning them to hold the lubricating oil in suspension in a non-soap thickened, grease structure. Has good high temperature characteristics, with a dropping point approximately 500☏, excellent water tolerance, good shear stability, and responds very well to additive treatments that enhance performance capabilities, such as oxidation and rust inhibition.
