PURPOSE:To obtain the title grease having durability at a high temperatures, having a suitably low degree of oil separation under no shear and showing a behavior of churning under shear. CONSTITUTION:The grease is prepared by adding about 5-20wt.% urea-type thickener to a base oil prepared by mixing a synthetic hydrocarbon oil with an ester-type synthetic oil in a weight ratio of (0.65-0.75):(0.35-0.25) and adding an antioxidant, a rust preventive, an extreme-pressure additive, an oiliness agent, etc., to the resulting mixture. This grease shows a behavior of churning under shear. |
