Document Type and Number:
Japanese Patent JP2002180077
Kind Code:
A
Abstract:
To provide a bearing having excellent acoustic characteristics, hardly causing fretting wear.
This lubricant composition is obtained by formulating a urea compound as a thickener with a synthetic hydrocarbon oil-containing non-ester oil as a base oil. The urea compound is represented by formula (I): R1-(NHCONH-R2)n (R1 is an aromatic hydrocarbon-containing group; R2 is at least one hydrocarbon group selected from a 6-12C alicyclic hydrocarbon group and a 6-20C aliphatic hydrocarbon group; n is 2-3). The synthetic hydrocarbon oil has ≥20 mm2/s and <80 mm2/s kinematic viscosity at 40°C and the amount of the synthetic hydrocarbon oil contained is at least ≥50 wt.% based on the whole base oil.
