Widely used in medium & small bearings. Suitable for low operating temps. Wide operating temps. From low to high. Mainly for light loads. Water included as a structural stabilizer. Unsuit-able for high temps. Emulsification phenomenon occurs with water. Used with relatively high temps. Suitable for vibration because of its good viscosity. Suitable for large sized bearings. Suitable for high temp. and heavy loads. Good for high temps and heavy loads. Poor water resistance. Suitable for high temps. Good for high temps.
