Applications
Application Considerations: Because Mobilgrease XTC is highly viscous and has adhesive agents to address coupling demands, use of hand- operated grease guns at low ambient temperatures without auxiliary heat is discouraged.
Mobilgrease XTC fully meets AGMA Type CG-3 requirements for high-torque, high-misalignment spindle couplings and AGMA Type CG-2 requirements for high-speed flexible gear and grid couplings. Mobilgrease XTC also meets less demanding AGMA Type CG-1 requirements. Mobilgrease XTC maintains its excellent performance characteristics in ambient temperatures up to 120º C. It is not recommended for temperatures below -30º C. Mobilgrease XTC is used widely in industrial applications requiring the use of:
Grid-type flexible couplings
Gear-type flexible couplings
