GREASE COMPOSITION FOR ENGINE BEARING

摘要

Disclosed is a grease composition for an engine bearing. The grease composition is a hybrid type grease composition which includes: a mixture of an ester-based base oil and a fluorine-based base oil as a base oil; and a mixture of a urea-based thickener and a fluorine-based thickener as a thickener. Accordingly, maximized effects in durability and heat resistance as the grease for an engine bearing may be obtained by optimally blending the base oils, the thickeners and the like.

1. A grease composition for an engine bearing, comprising:
an ester-based base oil; a urea-based thickener; and an additive, wherein the grease composition comprises the ester-based base oil in an amount of about 50 to 70 wt %; a fluorine-based base oil in an amount of about 18 to 30 wt %; the urea-based thickener in an amount of about 8 to 15 wt % of; a fluorine-based thickener in an amount of about 1 to 10 wt %; and the additive in an amount of about 1 to 10 wt %, based on the total weight of the grease composition.
