Mobilgrease XTC
Mobilgrease XTC is a premium high-performance grease specifically developed for lubrication of high-speed gear and grid couplings. It is formulated using a high-viscosity base oil combined with a heavy-duty additive system to deliver outstanding protection against wear, friction and corrosion. The formulation is engineered to provide low oil separation and excellent high-temperature stability, both of which are critical requirements for modern coupling lubrication and long-term reliability.
One of the key advantages of Mobilgrease XTC is its excellent resistance to oil separation (low bleed). This ensures the grease remains in place during operation, reducing leakage and maintaining consistent lubrication of coupling components. As a result, it helps improve coupling reliability, reduce lubricant loss and extend maintenance intervals.
Mobilgrease XTC also provides outstanding extreme pressure and anti-wear performance. The advanced additive system helps reduce friction and wear caused by sliding tooth contact, even in conditions where couplings may be misaligned. This contributes to longer component life, reduced wear rates and lower overall maintenance costs in demanding industrial applications.
Another important benefit is its excellent thermal and oxidative stability. The grease maintains performance at elevated temperatures and resists degradation, allowing for extended relubrication intervals and consistent protection over time. In addition, it offers strong resistance to rust and corrosion, helping protect coupling components in humid or contaminated environments.
Mobilgrease XTC is specifically designed to meet or exceed AGMA CG-1, CG-2 and CG-3 specifications, making it suitable for high-torque, high-speed and high-misalignment coupling applications. It is widely used across a broad range of industries where reliable coupling performance is essential, including heavy industry, manufacturing and processing environments.
The grease is particularly effective in grid-type and gear-type flexible couplings, where its adhesive properties and high viscosity help maintain a strong lubricating film under demanding operating conditions. It performs reliably at ambient temperatures up to approximately 120°C, ensuring stable operation in high-temperature environments.
Physical characteristics include NLGI 1 consistency with lithium complex thickener and dark brown appearance. Mobilgrease XTC has a base oil viscosity of approximately 680 mm²/s at 40°C and a dropping point of approximately 279°C. The grease delivers excellent adhesion, low oil bleed, high load-carrying capability and reliable long-term protection in high-speed coupling applications.
