Synthetic Aviation Grease
Product Descript ion
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.
The clay thickener gives Mobilgrease 28 a high dropping point
value of around 300oC, which provides excellent stability at high temperatures.
Mobilgrease 28 resists water washing, provides superior load-carrying ability,
reduces frictional drag, and prevents excessive wear. Tests show that
Mobilgrease 28 lubricates effectively rolling element bearings under conditions
of high speeds and temperatures. Mobilgrease 28 has also shown excellent ability
to lubricate heavily loaded sliding mechanisms, such as wing flap screw
jacks.
For more than 30 years, Mobilgrease 28 has been the multi-purpose
grease of choice for military and related aviation applications, worldwide.
