Mobil SHC 100 Aviation Grease, 4.4Lb Can
MOBIL
Description
Mobil Aviation Grease SHC 100 is a high-performance synthetic aviation grease formulated primarily for aircraft wheel bearing applications. It combines a polyalphaolefin (PAO) synthetic base oil with a lithium-complex thickener to provide wear, rust, corrosion and high-temperature protection over a wide operating range.
Mobil Aviation Grease SHC 100 is an NLGI Grade 2 / ISO VG 100 grease designed for high-speed, heavy-load applications such as aircraft wheel bearings, as well as landing gear bearings, slides and joints. It provides protection from approximately -65°F to 350°F (-54°C to 177°C).

Water and Environmental Resistance
Mobil Aviation Grease SHC 100 provides outstanding structural stability in the presence of water and is formulated to retain lubrication and component protection in adverse weather and wet operating environments.
Wear, Rust and Corrosion Protection
The synthetic base oil and lithium-complex thickener system provide protection against wear, rust and corrosion while maintaining grease structure under demanding aviation bearing conditions. ExxonMobil's published testing shows passing results for both copper strip corrosion and rust protection.
Packaging and Shelf Life
| BAC Package | BAC Part Number | Shelf Life |
|---|---|---|
| 4.4 lb can | SHC100-4.4LB | Up to 6 years unopened |
Storage: ExxonMobil recommends storing aviation greases indoors in a dry, cool and clean environment. Normal storage temperatures should be approximately 32°F to 104°F (0°C to 40°C). Once a container is opened, the grease should be used as soon as possible; the stated shelf-life recommendation no longer applies after opening.
