Can anyone advise me on what lubricant specifications are? We have a customer who is considering to change the grease used in the axis reducer on their Fanuc robots, is there a specification that I can reference?
Any help would be much appreciated!

What is the robot model, and which axis do they wish to change the grease for?

Maybe I am defeating the purpose of the forum but You should really call Fanuc for that question if you really want to keep the warranty on that robot.
It also depends on the temperature of the room, what axis, etc. Like Fabian said, I would surely check with Fanuc. Especially because it is your customer. If you recommend something from advice on here, at the end of the day you are on the hook. Not anyone here. At least with Fanuc, you can get it in writing from the manufacturer.
The standard grease is Nabtesco VigoGrease RE0.
If you are not concerned with warranty issues, I would contact the gear reducer manufacture, Nabtesco, as they would probably have a better insight than Fanuc. However, they will probably recommend their own house brand, which is what Fanuc supplies.
Why is your customer wanting to change?
Note: some wrist axes and smaller robots use different reducers. As others have asked, what robot and what joint?
Different models use different grease.
What model do you have?
All, thanks for the replies and concerns, I still don't have the information on models yet, but think the climate is controlled. Very aware of warranties and other issues. Will post models if I can get feedback today. Thanks again.
Yep ! Take care to follow the Fanuc recommendation for grease !
We have try replace it few years ago (based on astm spec) (some saving for somebody somewhere in the plant) and we blown a bunch of reducer (for $$$KKK) !!!
Some greases are in the top specification and other in the bottom (both still met ASTM) and that affect lubrification in a zero backlash reducer !
