Abstract: This disclosure relates to lubricants with certain amounts of calcium and zinc that tend to perform well in the low-speed FZG scuffing tests of CEC L-07 (FZG A/8.3/90) and further include certain amounts of low molecular weight diol and/or triol compounds to achieve good gear wear performance in FZG wear tests. The lubricants herein are suitable for use as industrial gear oils for transmission fluids (i.e., manual, automatic, or dual-clutch transmissions), gear fluids, axle fluids, differential fluids, and/or lubricating fluids for other gear-type applications configured for heavy-duty applications.

Abstract: Provided are a lubricant composition for shock absorbers, a lubricant additive, and a method of adjusting frictional property of a lubricant composition for shock absorbers, each capable of satisfying both the steering stability and ride comfort. The lubricant composition for shock absorbers contains a base oil and pentaerythritol esters and having frictional property represented by the following formula (1): RI>1.75×Fave−0.05  (1) supposing that a ratio ({Fsa−Fave}/Fave) of a difference, at the time of minute amplitude, between a peak frictional force Fsa in transition from a stationary state to a sliding state and an average frictional force Fave to the average frictional force Fave at the time of minute amplitude is responsiveness RI.

Abstract: There is provided a grease composition for improving the chemical stability of the grease composition and increasing the fatigue life of a member in which the grease composition is used. The problems can be solved by a grease composition including a poly-α-olefin; a urea-based thickener; molybdenum dithiophosphate; and barium sulfonate, wherein a difference between an SP value of the urea-based thickener and an SP value of the poly-α-olefin is 3.5 or less.
