Mobilgrease 33
Mobilgrease 33 is a high-performance lithium-complex grease developed for general-purpose aircraft lubrication. It is formulated with a 100% polyalphaolefin synthetic base oil and advanced additives to provide outstanding lubrication performance over a wide temperature range and operating conditions. The grease has a consistency between NLGI grades 1 and 2 and is designed for reliable operation in demanding aviation environments.
One of the key advantages of Mobilgrease 33 is its excellent thermal and oxidation stability. The synthetic polyalphaolefin base oil resists degradation at high temperatures while maintaining performance at very low temperatures. This helps extend grease life and protect lubricated components across a wide operating range.
Mobilgrease 33 also provides outstanding wear protection and load-carrying capability. The advanced additive system helps protect bearings, gears and actuators under high loads and shock conditions. The grease maintains a strong lubricating film, helping extend component life and improve reliability.
Another important benefit is its resistance to water washout and corrosion. The lithium-complex thickener provides excellent structural stability and helps maintain grease performance in wet environments. The formulation also provides strong rust and corrosion protection for critical aircraft components.
Mobilgrease 33 is intended for highly loaded anti-friction bearings, gears, actuators, instruments and general airframe lubrication. It is suitable for use across operating temperatures from approximately −73°C to 121°C and meets key aviation specifications including MIL-PRF-23827, Boeing BMS 3-33C and Airbus AIMS09-06-002.
Physical characteristics include NLGI 1.5 consistency with dropping point of approximately 255°C and blue-green appearance. Mobilgrease 33 offers low temperature torque performance, excellent oxidation stability and strong protection against wear, corrosion and water washout.
