ROLLING BEARING AND GREASE COMPOSITION USED THEREIN |
| 摘要 |
A rolling bearing including a plurality of rolling elements rollably provided between an inner ring and an outer ring and having enclosed therein a grease composition obtained by adding three kinds of antirust agents which are a carboxylic acid-based antirust agent, a carboxylate-based antirust agent and an amine-based antirust agent, to a base oil which contains at least one kind of a mineral oil and a synthetic oil and has a kinematic viscosity of 200 to 400 mm2/s at 40° C., the grease composition having a penetration of 300 to 400 and a yield stress of 150 Pa or less at 40° C. |

1. A grease composition for a rolling bearing, the grease composition obtained by adding three kinds of antirust agents which are a carboxylic acid-based antirust agent, a carboxylate-based antirust agent and an amine-based antirust agent to a base oil which contains at least one kind of a mineral oil and a synthetic oil and has a kinematic viscosity of 200 to 400 mm2/s at 40° C., the grease composition having a penetration of 300 to 400 and a yield stress of 150 Pa or less at 40° C. |
