EXXONMOBIL® MOBIL MOBILGREASE™ Aviation Synthetic Greases

EXXONMOBIL® MOBIL MOBILGREASE™ Synthetic Greases commonly used in aviation applications include MOBILGREASE™ 28 and 33 presented below. Other EXXONMOBIL®  products such as MOBIL MOBILTEMP SHC™ 100 Synthetic Antiwear Grease  (separately presented) are also used for aviation high speed, heavy load applications such as wheel bearings, as well as for slower speed, high load applications such as landing gear bearings, slides, and joints. 

MOBILGREASE™ 28

MOBILGREASE™ 28 is a supreme performance, wide-temperature, antiwear grease designed to combine the unique features of a polyalphaolefin (PAO) synthetic base fluid with an organo-clay (non-soap) thickener. Its consistency is between an NLGI No. 1 and No. 2 grease. It offers outstanding performance over a wide temperature range. The wax-free nature of the synthetic base fluid, together with its high viscosity index compared to mineral oils, provide excellent low temperature pumpability, very low starting and running torque, and can help reduce operating temperatures in the load zone of rolling element bearings. Designed to meet a specific combination of needs of aviation greases, namely the need to resist high temperature stresses, while providing excellent starting and low torque at low-temperature. This is achieved through MOBILGREASE™ 28 synthetic hydrocarbon base oils because of their low volatility, exceptional thermal/oxidative resistance, and superb low-temperature capability.

MOBILGREASE™ 28 meets the requirements of key military and commercial aviation specifications mentioned below, providing the following advantages and benefits.

- High viscosity index (VI) synthetic base stock with no wax content

- Allows wide operating temperature range - outstanding high and low temperature performance

- Provides thicker fluid films protecting against wear of equipment parts operating at high temperature

- Causes low resistance during start-up at very low temperatures

- Excellent protection against wear and corrosion

- Superb bearing protection and helps extend bearing life and reduce bearing replacement costs

- Extreme-pressure protection characteristics

- Avoids excessive wear, even under shock load

- High thermal/oxidative stability

- Long relubrication intervals

- High resistance to water washout

- Maintains excellent grease performance in adverse weather and other water-exposure conditions

Applications:

MOBILGREASE™ 28 is designed for the lubrication of plain and rolling bearings at low to high speeds, and splines, screws, worm gears, and other mechanisms where high friction reduction, low wear, and low lubricant friction losses are required. The recommended operating temperature range is -54ºC to 177ºC (-65ºF to 350ºF) with appropriate relubrication intervals. Also  recommended for use in: 

- landing wheel assemblies, control systems and actuators, screw jacks, servo devices, sealed-bearing motors, oscillating bearings, and helicopter rotor bearings on military and civil aircraft. Subject to equipment manufacturer approvals, it can also be used on naval shipboard auxiliary machinery and where superseded specifications MIL-G-81322 (WP), MIL-G-7711A, MIL-G-3545B, and MIL-G-25760A are recommended.

- industrial lubrication, including sealed or repackable ball and roller bearings wherever extreme temperature conditions, high speeds, or water washing resistance are factors. Typical industrial applications include conveyor bearings, small alternator bearings operating at temperatures near 177ºC (350ºF), high-speed miniature ball bearings, and bearing applications where oscillatory motion, and vibration create problems.

Qualifications, Specifications and Approvals

 MOBILGREASE™ 28 is qualified by the U.S. Military under Specification MIL-PRF-81322, General-Purpose, Aircraft, and Specification DOD-G-24508A (Navy) for shipboard auxiliary machinery. It is a U.S. Military Symbol WTR and NATO Code Number G-395 grease.
