摘要: The present invention relates to a hydraulic fluid composition containing a base oil (A), an antioxidant (B) including an amine-based antioxidant (B1) and a phenol-based antioxidant (B2), and a succinimide-based compound (C), wherein the hydraulic fluid composition satisfies the following requirement (I); and is to be used for hydraulic equipment which is equipped with at least one of a wet type brake and a wet type clutch and which is selected from a construction machinery, a general industrial machinery, and a power generator, and in which a working pressure is 30 MPa or more. The hydraulic fluid composition is not only excellent in wear resistance and an effect for suppressing the sludge formation but also excellent in a braking performance or a clutch performance, even when used under a high-pressure condition.
Requirement (I): A static friction coefficient (μs) after 1,000 cycles, as measured in conformity with the SAE No. 2 test described in JCMAS P 047:2004, is 0.100 to 0.162.-

摘要: Provided is a vacuum pump oil which contains a mineral oil (A) having a temperature gradient Δ|η*| of complex viscosity between two points of t(° C.) and t−10(° C.) (where −15≤t≤−10), as measured using a rotary rheometer at an angular velocity of 6.3 rad/s, of 10 Pa·s/° C. or less, and one or more compounds selected from a phenol-based compound (B) and an amine-based compound (C), and which has a viscosity index of less than 160. The vacuum pump oil has a good ultimate vacuum degree and is excellent in water separability, oxidation stability and shear stability, and is therefore applicable to various applications.
