Can you mix calcium sulfonate grease with lithium grease?
Lithium complex and calcium sulfonate grease both have the advantage of being compatible with each other and many other types of conventional grease lubricants. The only classes that are incompatible with a lithium complex and calcium sulfonate grease are traditional polyurea-based grease and bentonite clay grease.
What types of greases are not compatible?
Greases are manufactured from both mineral oil and synthetic oil bases. Some synthetic base oils are incompatible with mineral oils and other types of synthetics, just as in the mixing of lubricating oils. Therefore, it is important to consider the type of base oil in the grease when determining compatibility.
Can I mix calcium and lithium grease?
Lithium and calcium soaps were compatible with one another, and neither was particularly good when mixed with a clay-based grease. Compatibility of grease mixtures is typically categorized as follows: Compatible – The properties of the mixture are similar to those of the individual grease.
What grease Cannot be mixed?
But the two greases are incompatible. Lithium and polyurea greases cannot be mixed.
What is the difference between lithium and calcium grease?
Calcium sulfonate grease eliminates grease complex lithium both on the data sheet and on real applications. The main difference between these two types of grease is that greasety calcium sulfonate generally does not need additives to meet certain performance requirements such as grease lithium complex.
What is calcium sulfonate grease used for?
General applications for calcium sulfonate greases include automotive, agricultural, construction, food, industry, mining, paper manufacturing and steel mills. Specific automotive applications include chassis, ball joints, universal joints and wheel bearings.
Can you mix different greases?
Mixing of different greases can result in changes in physical and performance characteristics, leading to inferior properties of either of the original greases before mixing. Mixing incompatible greases often results in softening, but may also lead to hardening.
What is calcium sulfonate grease?
Calcium sulfonate greases are made by converting a fluid detergent that contains amorphous calcium carbonate to a grease containing calcite particles. Because of the calcite particles’ lubricating properties, performance additives containing sulfur, phosphorous or zinc may not be needed.
Is calcium sulfonate compatible with lithium complex?
Unlike lithium-complex greases, which need a significant amount of antimony-zinc or other types of additives, calcium-sulfonate thickeners have inherent extreme-pressure and anti-wear properties. Calcium-sulfonate greases are also compatible with lithium and lithium-complex greases.
What is calcium grease used for?
Calcium grease However, this lubricant is best used at lower temperatures, as high temperatures may cause changes in its structure. Today, calcium grease and calcium complex grease are mainly used in marine, industrial, automotive, and agricultural applications.
Is calcium sulfonate grease safe for plastic?
New Calcium Sulfonate Thickened Greases This product is recommended for high load applications operating under extreme conditions. Made with a PAO base oil, this grease is compatible with many plastics and elastomers used in the Automotive Industry.
Is calcium sulfonate grease compatible with polyurea?
Compatibility. That’s a big plus. In fact, the only greases that are incompatible with lithium complex and calcium sulfonate greases are conventional polyurea grease and bentonite clay grease (calcium sulfonate is also incompatible with calcium complex grease, but you wouldn’t typically put those two together).
What is calcium complex grease made of?
Calcium complex grease is made by reacting two dissimilar acids with hydrated lime to form a complex molecule. These dissimilar acids, acetic and stearic, when increased to the proper amounts, will yield a natural, high, extreme-pressure rating, usually around a 55 on the Timken O.K. Load. This is one of their advantages.
Can I use polyurea Grease with lithium or lithium complex thickeners?
Some polyurea thickeners are completely compatible with lithium and lithium complex thickeners, while other polyurea thickeners are definitely incompatible with the lithium and lithium complex thickeners. It is necessary to perform compatibility testing on combinations of these greases to determine whether the greases can be mixed in service.
Why is grease compatibility so confusing?
Grease compatibility is often confusing to grease users, even though most grease manufacturers produce compatibility charts. This is because the charts from the various manufacturers often disagree with one another on certain thickener-type combinations.
