Grid and gear coupling grease SKF LMCG 1/0.4

A polyethylene thickened and mineral oil based grease SKF LMCG 1/0.4 which also uses a lithium complex thickening technology. The grease is formulated to withstand high centrifugal forces and high-torque applications for grid and gear (flexible) couplings even where severe shock loadings, misalignment and vibration occur.

Leakage is prevented at high speeds and the grease is stable in consistency. The special additive formulations make the grease suitable for applications subjected to high loads, high torque, wet environments, a wide range of speed regimes and wide range of temperatures.

• Excellent resistance to oil separation
• High acceleration and high operating speeds
• Excellent high-torque lubrication
• High corrosion protection
• Exceeds AGMA Type CG-1 and AGMA Type CG-2 requirements
• High coupling wear protection
• Excellent oxidation stability
• Due to low oil bleeding tendency, suitable for use in centralized lubrication systems'
