Problems solved by technology

However, this method has a problem of increased heat generation due to higher viscosity, resulting in increased stirring resistance
[0010] When the oil film is thinned, microscopic protrusions on the surface come into contact, and peeling from the surface tends to occur, resulting in shortened life

Embodiment

[0086] Preparation of test grease:

[0087] Grease compositions of Examples and Comparative Examples were prepared using the thickeners, base oils, and additives shown in the table below. Specifically, diphenylmethane diisocyanate was reacted with a predetermined amine in a base oil, heated and cooled, and kneaded by a three-roll mill to obtain grease compositions of Examples and Comparative Examples.

[0088] The thickener amount was adjusted so that the working penetration (test method JIS K2220 7.) of the grease composition was 300.

[0089] The grease composition prepared above was evaluated by the following test method. The results are shown in the table below.
