MIL-G-25013 - Aircraft Ball and Roller Bearing Grease (NATO Code G-372)
We perform grease quality testing according to military specification MIL-G-25013, which covers an aircraft lubricating grease used in anti-friction bearings. This grade of grease is used in anti-friction bearings where operation of low torque equipment will require lubrication for extended periods at low and high temperatures. This grease is identified by NATO symbol G-372.
