Mobil Aviation Grease SHC 100 (Case of 4 - 4.4 lb Cans)
Mobil Aviation Grease SHC 100 is a supreme performance NLGI Grade 2 synthetic grease approved as a wheel bearing grease by all major aircraft wheel manufacturers. Combining the unique features of a polyalphaolefin (PAO) synthetic base fluid with a high-quality lithium complex soap thickener, Mobil Aviation Grease SHC 100 exhibits excellent resistance to water, and shows outstanding bearing protection in a wide range of temperatures. Mobil Aviation Grease SHC 100 has been proven to maintain top performance in preventing wear, rust and corrosion under severe conditions. The wax-free synthetic base oil provides low-temperature mobility and pumpability, as well as low starting and running torque values. Mobil Aviation Grease SHC 100 is a top choice for high-speed heavy load applications such as wheel bearings, plus slower speed high-load applications including landing gear bearings, slides and joints.
A key factor in the development of Mobil Aviation Grease SHC 100 was the close contact between ExxonMobil product engineers and key OEMs to ensure that the lubricant would provide exceptional performance in aircraft wheel bearings. This work has helped to confirm the results from ExxonMobil laboratory tests showing the exceptional performance of Mobil Aviation Grease SHC 100 including long grease life, enhanced bearing protection and bearing life in aircraft wheels, and wide temperature range of application.
To combat high thermal exposure of the oil, ExxonMobil product formulators chose synthetic hydrocarbon base oils for Mobil Aviation Grease SHC 100 because of their exceptional thermal/oxidative resistance potential. A state-of-the-art lithium complex thickener technology was developed and used specific additives to enhance performance.
Mobil Aviation Grease SHC 100 offers the following features and benefits:
|Features||Advantages and Potential Benefits|
|High viscosity index (VI) base stock with no wax content||Wide application temperature ranges, with excellent protection at high temperatures and low torque, easy start-up at low temperatures.|
|Outstanding high temperature and low temperature performance||Thicker fluid films protecting against wear of equipment parts operating at high temperature|
|Excellent protection against wear, rust, and corrosion||Reduced downtime and maintenance costs because of reduced replacement of equipment parts|
|Excellent structural stability and oxidation resistance||Long intervals between re-lubrication and improved bearing life|
|Outstanding structural stability in the presence of water||Excellent grease retention on parts in hostile wet environments|
|Low volatility||Little loss of lubricating oil|
Mobil Aviation Grease SHC 100 is recommended for aviation applications which need a lubricant that can perform normal functions, yet go far beyond in terms of high and low temperatures and long-life performance. It is a NLGI Grade 2/ISO VG 100 grease having the cold-temperature pumping resistance of most mineral-oil NLGI Grade 0 greases. It provides outstanding protection at operating temperatures from –54 ºC (-65 ºF) to 177 ºC (350 ºF).
Mobil Aviation grease SHC 100 is recommended for 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.
Mobil Aviation Grease SHC 100 is approved as a wheel bearing grease by all major aircraft wheel manufacturers.
