Mobilgrease 33 (NLGI-1.5) [13.4-oz./379.88-g. Tube] 121963

MSDS

PDS

Mobilgrease 33 is a high-performance lithium-complex grease designed for general-purpose aircraft use. Its consistency is between the NLGI grades 1 and 2. Mobilgrease 33 utilizes a 100% polyalphaolefin base oil and premium additives which ensure outstanding lubrication performance over a wide temperature range and operating conditions.

Features

• The lithium complex thickener system provides excellent structural stability and resistance to water wash-out. Polyalphaolefin base oil is used in Mobilgrease 33 because of its exceptional thermal/oxidative resistance potential, low volatility, and superb low-temperature capability, without the potential vulnerability of an ester base oil to degradation from reaction with water. The synthetic polyalphaolefin base oil offers excellent low-temperature mobility/pumpability and very low starting and running torque values. In addition, the state-of-the art additive system in Mobilgrease 33 provides superior rust and wear protection and load-carrying capacity compared to aviation greases that meet the minimum requirements of the MIL-PRF-23827 specification. Mobilgrease 33, with its unique features, provides the following advantages and potential benefits:
• High viscosity index polyalphaolefin basestock - Very wide operating temperature range - outstanding high and low temperature performance. Excellent lubricant film protection at high temperatures.
• Good storage stability - Grease structure integrity maintained - low oil separation.
• Exceptional resistance to thermal and oxidative degradation - Long grease and lubricated part service life.
• Low volatility - Little vulnerability to significant base oil loss by evaporation in service.
• Resistance to degradation by water (hydrolysis) - No risk of corrosion induced by acidic base oil degradation products.
• Excellent protection against wear, corrosion, and rusting - Excellent bearing and component protection.
• Extreme-pressure characteristics - Prevention of excessive wear, even under shock load.
• High resistance to water washout - Excellent grease performance in adverse weather and other water-exposure conditions.
