摘要:
A grease composition is produced by mixing a thickener comprising a fluoro resin and a second thickener component (a metallic soap, a complex metallic soap, an N-substituted terephthalamic acid metal salt, organic bentonite or a calcium sulfonate complex) into a base oil. This grease composition is excellent in heat resistance, load carring capacity, water resistance, rust protection, lubricating life and the like. A rolling apparatus filled with the above grease composition has excellent lubricating ability and is long-lived under high-temperature conditions. Moreover, a grease composition is produced by mixing a thickener comprising a fluoro resin and carbon black as a second thickener component into a base oil. This grease composition is excellent in heat resistance, water resistance, rust protection, lubricating life, electric conductivity and the like. A rolling apparatus filled with the above grease composition has excellent electric conductivity and is long-lived under high-temperature conditions.
