Grease for hub bearing and hub bearing |
| abstract |
A hub bearing, of carbon steel for machine use, which has a long life because of improved resistance to peeling starting from the surface and a grease enclosed in the hub bearing which contains a base oil and a thickener, and in the base oil, the number of naphthenic carbons found by an n-d-M ring analyzing method accounts for 32 to 37% of a whole number of carbon atoms in the base oil. The base oil is a mineral oil or a mixed oil of a mineral oil and a synthetic hydrocarbon oil. The thickener contains 1 to 40 mass % of a urea compound of formula (1): n nwhere R 2 indicates an aromatic hydrocarbon group having 6 to 15 carbon atoms, and R 1 and R 3 indicate at least one hydrocarbon group selected from an alicyclic hydrocarbon group and an aromatic hydrocarbon group. |
