ExxonMobil® Mobilgrease 28 Synthetic Aircraft Grease, Red Color, 13.4 oz Tube

This grease has a consistency between NLGI No. 1 and No. 2, providing excellent low-temperature pumpability and very low starting and running torque. The wax-free synthetic base fluid, along with its high viscosity index, helps reduce operating temperatures in rolling element bearings. The clay thickener gives Mobilgrease 28 a high dropping point value of around 300ºC, ensuring stability at high temperatures. It resists water washout, provides superior load-carrying ability, reduces frictional drag, and prevents excessive wear. Mobilgrease 28 lubricates effectively under high speeds and temperatures, making it suitable for heavily loaded sliding mechanisms, such as wing flap screw jacks. It is designed for the lubrication of plain and rolling bearings, splines, screws, worm gears, and other mechanisms requiring high friction reduction and low wear. The recommended operating temperature range is -54ºC to 177ºC (-65ºF to 350ºF) with appropriate relubrication intervals. Mobilgrease 28 is also recommended for industrial lubrication, including sealed or repackable ball and roller bearings in extreme conditions.
