MIL-PRF-23827 - Aircraft, Instrument, Gear and Actuator Screw Grease Specification

We perform quality and conformance testing by Military Specification MIL-PRF-23827, which covers a low-temperature grease used on aircraft and instruments.

This lubricating grease is identified by NATO G-354. This grease is intended for use in ball, roller and needle bearings, gears, and on sliding and rolling surfaces of equipment such as instruments, cameras, electronic gear and aircraft control systems that are subject to extreme marine and low temperature conditions not encountered in commercial aviation. It can also be used for rolling and sliding surfaces of equipment with low motivating power (low torque equipment). This lubricating grease has an extremely low volatility, which is advantageous in preventing oil fogging in aircraft optical instruments. This grease can be used on aircraft gears and actuator screws.
