Abstract:
PROBLEM TO BE SOLVED: To provide a heat-resistant, high speed, and high-loaded rolling bearing, which is used for accessory units or electrically-powered components, having non abnormal flaking phenomena, sufficiently long life, and superior durability under high temperature, high speed, and high loading operating conditions. SOLUTION: Grease composition, in which diurea compound showed in the following chemical expression 5 is combined as a thickener and a passive agent such as sodium nitrite is also added at 0.1 to 5 wt.% in base oil mixed alkyl diphenyl ether oil and aromatic ether oil with 20 to 150 mm 2 /s of dynamic viscosity at 40°C in a range from 50:50 to 80:20 (weight ratio) and is filled in the heat-resistant, high speed, and high-loaded rolling bearing. (where, R 2 shows an aromatic hydrocarbon group having 6 to 15C, R 1 and R 3 show an aromatic hydrocarbon group having 6 to 12C, or an cycloalkane family hydrocarbon group having 6 to 20C, a rate of aromatic hydrocarbon of R 1 and R 3 occupied in a full amount are 1/2 or more in a mole ratio, and R 1 and R 3 may be the same or different.

Abstract:
In a process for manufacturing a calcium complex grease in which there is incorporated an ethylene-vinyl esterorganic acid terpolymer as an improving agent, a method is provided for improving grease formulation, obtaining improved yield and making use of previously unsuitable oils by introducing the terpolymer to the charge of the lubricating vehicle and thickening agent components prior to saponification.
Abstract:
PROBLEM TO BE SOLVED: To provide a grease composition capable of obtaining a sufficiently satisfiable long life even under a high temperature on sealing the same in a roll bearing and a bearing sealed with the composition. SOLUTION: This grease composition comprises a perfluoropolyether as a base oil, and at least 10 mass% melamine cyanurate as a thickening agent based on the total composition, and the bearing sealed with the composition is also provided.
