摘要： A grease composition is produced by mixing a thickener of a calcium sulfonate complex and a second thickener component (polyurea, a metallic soap, a complex metallic soap or an N-substituted terephthalamic acid metal salt) into a base oil. This grease composition is excellent in heat resistance, load carrying capacity, water resistance and lubricating life. Moreover, a grease composition is produced by mixing a thickener of an N-substituted terephthalamic acid metal salt and a second thickener component (polyurea, a metallic soap or a complex metallic soap) into a base oil. This grease composition is excellent in heat resistance, oxidation stability and lubricating life. Furthermore, a grease composition is produced by mixing a thickener of 10 to 90% by mass of polyurea and 90 to 10% by mass of a complex metallic soap into an ester oil having a kinematic viscosity at 40null C. of 20 to 180 mm2/s. This grease composition generates only a few dusts even at a high temperature and has excellent high-temperature performance. Still further, a grease composition is produced by mixing a thickener of 10 to 90% by mass of polyurea and 90 to 10% by mass of a complex metallic soap into a base oil having a kinematic viscosity at 40null C. of 50 to 500 mm2/s. This grease composition has excellent performance under a high-speed and high-temperature environment and provides a rolling apparatus with excellent seizuring life.
