Grease Residual

U uniquethMember
Gentlemen,

Could anyone clarify about the greases which will leave residuals at their usage for me? I've learnt that the greases without dropping or melting point (non-soap or synthetic grease) will leave the residuals to that part/bearing; while the soap-based greases which have their dropping or melting point like Calcium, Lithium, Complex soap, even Polyurea and Calcium Salfonate should leave no residuals to the part/bearings. Is it always true for this concept? If not please kindly help me clarify the idea, because there're not many sources of this information I can find.

Now I'm facing the Polyurea residuals problem which is used at 200C and it forms itself to be residual like hardened soil. I've attached the picture for you gus to see how it looks. If the Polyurea can form this soil-like residuals then what I've known was all wrong and I need some advice for this knowledge.

Is there anyone can advise me? I'll be really appreciated for your help.

I'm not exactly sure what your asking, but I think your problem may be overworking your grease. Either your temps are to high for the grease your using or your not greasing often enough.

When the lubricating oils of the grease are used up, what remains is the thickening agent. That can look like what your describing or leave a "chalky" feel.

Thank you for your answering JMorgan.

I also agreed with your idea for not re-greasing oftenly. And the based oil was all used up, leaving the thickening residues like you've seen. So, the way to sort it out is to re-greasing more oftenly so that the new grease will be replaced the used grease to come out.

The thing I tried to explain I guessed it was my personal misunderstanding.

I'm appreciated your answer, and all answers you've done. I've got so many knowledges from you.

Uniqueth,

Have you considered the base oil viscosity of the grease you are using and calculated the required viscosity?

Personally, I haven't found an iron clad method for grease base oil requirements, but the literature is out there for oil viscosity, I use that as a starting pint and then typically use a higher viscosity base oil in the selected grease.

That has helped solve some issues with problem machines here.

All polyurea greases are not the same its depend how much % of polyurea has been used for making that grease. Try Elba Polysyn 2 its very good and can solve your problem its www.elba-lubes.com

1 Question

1. Do you work for an Omega distributor??

THe image yuou have shopwn is a typical under greasing with a polyurea grease being applied at high temperature, one of the advantages with polyurea thickner is that lightly heat gelled polyurea thickner can be picked up again by the new grease, to prevent "drying" the grease out, increase the anmount of grease being appied by shortening the duration between application, eg: if applying every 4 days apply every 2 days, adjust this on the amount of "drying" out observed on the used grease, if you want to apply and forget then a polyfluoroether may be more useful.

Thank you rttech!

I don't work for OMEGA, OMEGA products left me so many questions thats why my questions were regarded to OMEGA's products.

Thanks for your recommendation about the re-greasing duration. I have the same idea with you, but the thing is the price for PFPE always scares my buyers and decision makers once I raise to them. So, frequent re-grasing should be the best answer.
