摘要： A grease for a bearing of a fan comprises a base oil selected from a various kinds of silicone oils having a viscosity of 30 to 500 mm2/s at 40 degree-C. and a viscosity of 30,000 mm2/s or less at −30 degree-C., and a diurea compound, as a thickening agent, at the compounding ratio of 2 to 30%-wt. The urea compound has a general formula of: R1—NHCONH—R2—NHCONH—R3 wherein R2 indicates a tolylene group, a diphenylmethan group or a dimethylbiphenylene group, and R1 and R3 respectively indicate a straight chain saturated alkyl group having the number of carbon atoms of 6 to 18, and an alicyclic group, and wherein the ratio of the straight chain saturated alkyl group to the alicyclic group is within a range of 5 to 95 mol-% to 95 to 5%-mol. The grease maintains its properties suitable for use in a fan, and effectively restrict or prevent generation of hoot sound, while providing satisfactory durability and cost-effctiveness.

摘要： According to the present invention, PAO oil and ester oil are mixed in a ratio by weight of from 50:50 to 90:10 to provide a base oil having a viscosity of not more than 70 mm2/S at 40° C., to which base oil is then added 5-25% by weight of diurea, which is an alicyclic compound, serving as a thickener, and ZnDTC, which is an additive. The grease thus prepared is filled in a bearing 2. This bearing 2 is fitted in the inner portion of a pulley body 1 having a pulley peripheral surface is to be contacted by a belt driven by the engine of an automobile. Thereby, brittle peeling occurring in the raceway surfaces and ball surfaces, and abnormal noise under cold ambient can be reliably prevented.

摘要： Disclosed is a grease sealed bearing for automobile that has the high temperature resistance as well as shear stability, and prevents the noise at low temperature as well as the brittle flaking under high speed rotation and high load. The grease comprises a base oil containing a synthesized hydrocarbon oil and one or more ester oils at a weight ratio of 0.1 to 0.49:0.9 to 0.51; 5 to 30% by weight of a urea based thickener, and 0.1 to 10% by weight of dithiozinc phosphate based on the whole grease. The grease sealed bearing for automobile is obtained by sealing a bearing used in a device driven by an automobile engine with the grease.
