  • Publication number: 20090069203
    Abstract: A heat reversible gel-like lubricating composition having such properties that, in a service bulk temperature region, the composition is in a semi-solid gel form as with grease, but in a local high-temperature region such as a sliding contact site, the composition is homogeneously melted, is free from grease, i.e., the precipitation of foreign materials, exhibits excellent low frictional characteristics unrealizable by grease, and exhibits significant energy saving properties. The heat reversible gel-like lubricating composition includes a mineral oil and/or synthetic liquid lubricating base oil and a bisamide and/or a monoamide and has heat reversible gel properties. Preferably, the heat reversible gel-like lubricating composition contains a triamide and further contains, based on 100 parts by weight of the liquid lubricating base oil, 0.01 to 500 parts by weight in total of a bisamide and a monoamide and 0.05 to 10 parts by weight of a friction regulator.
