MIL-PRF-81322 - Wide Temperature Range General Purpose Aircraft Grease Specification
We perform quality and conformance testing by Military Specification MIL-PRF-81322, which covers a general purpose lubricating grease used in aircraft. This grease, identified as NATO Code G-395, can withstand high speed operations over a wide temperature range. This grease is intended for use in military aircraft wheel bearings and internal brake wheel assemblies, anti-friction bearings, gearboxes, and plain bearings.
