Product Description: Mobilgrease 28 is a high-performance, synthetic aviation grease designed for a wide temperature range. It combines a polyalphaolefin (PAO) synthetic base fluid with an organo-clay thickener, offering excellent low-temperature pumpability and high-temperature stability. It is effective in reducing friction and wear in rolling element bearings and heavily loaded sliding mechanisms.

Features and Benefits: Mobilgrease 28 is formulated to resist high temperature stresses while maintaining low torque at low temperatures. It uses proprietary synthetic base oils for low volatility and thermal/oxidative resistance. The grease meets key military and commercial aviation specifications, providing advantages such as wide operating temperature range, superb bearing protection, extended bearing life, and high resistance to water washout.

Applications: Suitable for lubricating plain and rolling bearings, splines, screws, worm gears, and other mechanisms requiring high friction reduction. It is recommended for use in aircraft landing wheel assemblies, control systems, and helicopter rotor bearings. It is also applicable in industrial settings for bearings exposed to extreme temperatures and water washout.

Specifications and Approvals: Mobilgrease 28 meets U.S. Military Specification MIL-PRF-81322 and DOD-G-24508A, and NATO Code Number G-395. It is approved for various military and industrial applications.

Typical Properties: The grease has a dropping point of 315ºC, low temperature torque at -54ºC, and high resistance to evaporation and corrosion. It maintains stability under high temperature and pressure conditions.

Health and Safety: Mobilgrease 28 is not expected to produce adverse health effects when used properly. Safety information is available in the Material Safety Data Sheet (MSDS).
