Grainger has been out of Polyrex EM for quite some time and I’m down to my last couple of tubes. They keep recommending various lithium based greases as alternatives. I was under the impression hat mixing lithium base with polyurea base was a no-no.

Is my concern valid, or not an issue? And can anyone suggest a couple of acceptable substitutes that I can ask about at the supply house?

I might be able to send you a couple of tubes or more. I'm pretty sure my local supply house has them.

No you shouldn't MIX grease but that doesn't mean you can't repack the bearings.

true but i mean for 5-40hp
motors that are just getting regular maintenance. just a shot or two of grease. I wouldnt mess with pulling out and repacking the bearings unless it was an emergency

Home depot has it, auto parts stores, United refrigeration, it's out there, just gotta forget about grainger, they're too expensive anyway.

And no, DO NOT mix greases with different bases...it can cause separation, and lack of lubrication.

Maybe in Colorado but here nobody can even order it except one supply house who happens to carry it on the shelf.
But yeah I agree with the point forget about Grainger there's more fish in the sea or um.... grease on the shelves.

Yep someone has it somewhere. When capacitors got scarce at the supply house I went to the appliance store and they had them.

Send or call mobile and ask them what is an alternative or who is a vendor close to you who might have it in stock. but I find it can be ordered and bought many places on the internet.

What bothers me about this whole scenario, and which is why I asked, is because I already knew that. And yet, I keep getting recommendations from Grainger, not only online, but by sales personnel to use this or that other grease, and invariably it's a lithium-based grease that they want me to buy in place of a different-based one. I don't get why their system (apparently) doesn't at least try to match the type. I mean, they're already categorized by type to begin with, when you're looking them up.

I get that counter guys and salespersons aren't mechanics, and also that Grainger is not a specialty shop like for bearings and/or lubricants, but isn't that kind of a bad thing? I doubt I'm the only person who orders grease from them, how many people would just order whatever they say and pump it in and not care about possible problems.

Many people don't understand grease and most just don't care.

Lubriplate mag 1 is compatible. As is any other polymer grease

Yup....all about the base material.

Grease is basically oil suspended in soap (generic exanation).

Different base materials can cause that oil to separate, and drop out, leaving no lubricant.

We're in the open forums, so I always recommend no mixing bases......
