NS-3913-G1

Specifications NSN 9150-00-506-8497 Bell Helicopter 204-040-755-005 NS-3913-G1 Gear and Coupling Grease (NSN 9150-00-506-8497) NS-3913-G1 is an extreme pressure fortified grease designed for couplings and gears. High film strength components provide long lasting protection. EP and anti-wear additives along with rust inhibitors provide excellent performance for applications ranging from aerospace such as helicopter drive shaft couplings and bearings to industrial applications such as steel mill gear couplings. NS-3913-G1 is the only lubricant approved by Bell Helicopter Textron for use on their Crown Gear Driveshaft couplings. Characteristics: Superior lubricity - low friction, less wear High film strength EP and anti-wear additives Wide operating temperature range of -40°F to +300°F Typical properties Penetration, ASTM D217, worked, 60 DS Penetration, ASTM D217, worked, 100,000 DS Dropping point, ASTM D2265, °F(°C), min.
