I know normally a moly grease does not carry the wheel bearing (GC) NLGI approval, but are there any that figured out how to run Moly in a high speed application that got the GC-LB approval?

Few question before I give answers.
1. How high is the high-speed application? Any DN number?
2. Do you have schock loads - if yes can you qunatify them?
3. What is the main reason to search for molly grease?
I've heard Moly plates out in high speed applications. I had a guy tell me anything spinning faster than 1800 rpm would plate out and I'd roast my bearings.

Hi is right.
High DN rolling applications - especially needle bearing dont like moly.
I know that molly is hype now. Grase manufacture try to profit of it an introduce GC-LB greses with minimal % of moly but just enough to be on label.
In general greases with moly lower dan 3% moly can be GC-LB certified - and sell at premium product.
Back to my questions - What is your application ?Do you really need Moly?
