Here are a couple of quotes from Exxon regarding their Moly EP type greases (emphasis added):

RONEX EXTRA DUTY MOLY 2 is recommended for high load applications at slow-to-moderate speeds, including applications in the paper, construction, and mining industries, as well as off-highway vehicles operating at 35 mph or less. RONEX MP, with its much lower base oil viscosity of 767 SUS, is designed to meet a wider range of high-speed industrial and automotive bearing applications, including wheel bearings in on-highway use.

Beacon EP 2 Moly is suitable for plain bearings and gears. It also can be used in rolling contact bearings, but is not generally recommended for high-precision rolling contact bearings because of the possibility of molybdenum disulfide building up in the clearances.
