grid and gear coupling grease skf lmcg 1 0 4A 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
