|When you think of lithium two things may come to mind: (1) batteries and (2) a song by a famous grunge band. Newsflash—lithium has many industrial uses including serving as a form of lubrication.|
Whenever metal-on-metal (and even metal-on-plastic) friction is an issue, this type of grease is choice #1. Its application is diverse, evident by the term "multi-purpose" that often precedes its name. Use it on joints, bearings, and suspension systems. They also have specific applications such as on missile systems and Unmanned Aerial Vehicles (ROYCO 757®). It doesn't matter; the products on this page are well suited for aircraft components subjected to high stress.
They also act—like all good lubes—as corrosion and oxidation inhibitors. That means they reduce friction while lasting a long time. An additional benefit: they are heat-and water-resistant. That's good considering the everyday operations associated with flight.
In spray can or tube or other, lube the right parts with the right lithium grease. You've landed on the right page.
