Lubricants qualified under U.S. Military specification MIL-L-2105D (formerly MIL-L-2015C), MIL-PRF-2105E and SAE J2360 satisfy the requirements of the API GL-5 service designation. API Category GL-6 (inactive [3]) designates the type of service characteristic of gears designed with a very high pinion offset. Such designs typically require (gear ...
Many military specifications and standards were canceled. In their place, the DOD directed the use of performance specifications and non-government standards. "Performance specifications" describe the desired performance of the weapon, rather than describing how those goals would be reached (that is, directing which technology or which ...
Cosmoline could be found on military equipment in the Spanish–American War, World War I, World War II, and the Korean and Vietnam Wars. [4] [5] Cosmoline conforms to MIL-SPEC (MIL-C-11796C, Class 3) for Preservative and Sealing Compounds. [6] Chemically, cosmoline is a homogeneous mixture of oily and waxy long-chain, non-polar hydrocarbons.
It is based on MIL-STD-1464A which was released in 1981 [1] and most recently revised on February 22, 2021. [2] Usage.
Failure to use the correct specification oil has been known to cause PCV (positive crankcase ventilation), VVT (variable valve timing) system, gasket and sealing system, and other internal combustion component premature clogging and other failures. Some of the additives in those specs are designed to aid in keeping systems lubricated and clean.
Dry lubricants or solid lubricants are materials that, despite being in the solid phase, are able to reduce friction between two surfaces sliding against each other without the need for a liquid oil medium. [1] The two main dry lubricants are graphite and molybdenum disulfide. They offer lubrication at temperatures higher than liquid and oil ...
