Hello,

This is a new plant. We extracted the lube requirements from the technical manuals provided and other information found on equipment name plates. 
Practically all lube recommended come from three manufacturers: Esso, Mobil and Shell.
Is there someone who could point me to an equivalent chart/list of products (greases) among these three suppliers, please? Thank you.

Batman, post your physical location because brand names sometime differ depending on geography.  In the interim, see if any of the following are helpful.

Batman the application of the greases should be the starting point to spec a replacement, has it to work with barrier friction or dynamic friction or a combination of both? have you a requirement to use ones outside the OEM recommended 3? 
When asked for an equivalent to a grease used by a customer, I always ask what the application is, we then try and offer a better product as in most cases the bare minimum requirement is specced by OEM.

We sell Kluber and they have a good guide for grease selection according to the application.
Use the guide on the first Link and between pages 5 and 8 to identify the running characteristics of the machine then the second document has the list of the specific products.

Thank you John & Mark for your posts.

I'm afraid I can't deviate from the recommended lubes because of warranty reasons.

cheers

No problem batman, if you cannot deviate from those brands what exactly are you looking to achieve? Maybe I read incorrectly I thought you wanted an alternative?

Hello Mark,

Please excuse my late reply...missed this completely and you deserve a reply.

Well, Kluber does not appear on the recommended lubricants list. These are mainly esso/mobil/shell so I can't consider Kluber products for the time being.


What I'm trying to achieve is to get the equivalent products of these three brands for each recommended product.

Let's say we have 3 pieces of equipment with the following lube recommendations:

 essomobilshell
1xx?
2x?x
3?xx

If I manage to get the missing equivalent ones (?), this makes it easier to select one brand for all the three. We would like to outsource the lubrication services and would like to reduce the number of different lubricant brands to be used.
 

Thank you.

Batman, for case #1 I would contact a vendor of Shell products and ask them to recommend an equivalent to Esso/Mobil. For case 2 contact your Mobil vendor and ask them for an equivalent Esso/Shell product. Similarly for case 3. They are supposed to be experts -- let them do the work. Ask for the "recommended" equivalents, and get it in writing in case there is a problem with their recommendation down the road.

You don't need to explain to them exactly what you are doing, but let them know you are "evaluating" your lubrication options. Let competition work in your favor, and perhaps a single vendor comes to the fore in terms of price and/or service.

What I see by your 3 x 3 matrix is two brands that are closely related, Esso and Mobil.  Between the two of them all three of your machine are covered.  I would be taking machine 3 that has a Mobil product and then go back to the OEM for approval to use an equivalent Esso product.

Batman-did you get this issue resolved?

IMHO this is an exercise that doesn't need to be undertaken if you are dealing with "normal" industrial equipment such as motors, pumps, fans etc. If you go with a good grease from one of the major suppliers such as Mobil/Texaco/Kluber etc. any machine failure under the warranty would be almost impossible to attribute to the "wrong" grease. OEMs list a few oils and greases in their maintenance manuals that work but it is not an exclusive list. Check the actual specs. There really isn't that much difference in the grease that is out there. Decide on 1 grease for motors, maybe 2 or 3 for other equipment and you will be good. Off the top of my head I would speculate that 95% of grease related failures are application failures (over greasing/under greasing, too little, too much) and maybe another couple percent is mixing of the different types of grease. Make an effort to start with a good grease, applied in the right quantity at the right frequency and you will be golden.
