Is polyurea and lithium grease compatible?
Is polyurea and lithium grease compatible?
Lithium and polyurea greases cannot be mixed. “They can cause each one to lose their oil and dry out,” said Hamilton. The product loses the ability to lubricate.
Is polyurea grease good for wheel bearings?
Polyurea greases are a preferred choice for filled-for-life applications in bearings and are important in steel plants and electric motors.
What is polyurea grease used for?
Polyurea grease is a non-soap thickened grease that is becoming widely accepted as the best option for long life applications such as electric motor bearings, automotive and off highway constant velocity joints and seal for life applications.
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.
Can you mix polyurea Grease with lithium grease?
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.
Which is better for lubrication lithium or polyurea?
Hardening of the grease can result in even worse problems, since the grease can no longer flow into the bearing cavity, leaving the bearing starved for lubrication. However, polyurea thickeners do offer some advantages over lithium thickeners. For instance, polyurea greases are often the preferred choice for sealed-for-life applications.
Which is better Graco grease or lithium complex?
Lithium complex is the thickener that is most compatible with other thickeners. There are only a few other thickeners that are not compatible with lithium complex, when using one of the Graco greases.
Are there any advantages or disadvantages to using polyurea grease?
Are there any advantages or disadvantages to using a polyurea grease over a lithium-complex grease if all the other factors are equal?” When comparing a polyurea grease to a lithium-complex grease, the biggest drawback is that polyurea thickeners are quite incompatible. This incompatibility can cause hardening or softening of the grease.
