AEROSHELL GREASE 22

"AeroShell Grease 22" is especially recommended for use wherever severe operating conditions are encountered as in high bearing loads, high speeds, wide operating temperature range, and particularly where long grease retention and high resistance to water washout are required. The wide range of applications include aircraft wheel bearings, engine accessories, control systems, actuators, screw-jacks, servo mechanisms and electric motors, helicopters rotor bearings, instruments, airframe lubrication, hinge pins, static joints, landing gears. May be used as analogue of Russian greases CIATIM-201, CIATIM-203, CIATIM-221, VNII NP-207, ERA (VNII NP-286Ì) and NK-50.

Conform to the specifications: MIL-PRF-81322F, DOD-G-24508A, DEF STAN 91-52 and others.
