To provide a conical roller bearing having an excellent bearing life under a rotation condition that a change of a rotational speed is large.SOLUTION: A conical roller bearing 11 comprises: an inner ring 12 having a tapered raceway surface 12a at an external peripheral face; an outer ring 13 having a tapered raceway surface 13a at an internal peripheral face; a plurality of conical rollers 14 rolling between the raceway surface 12a of the inner ring 12 and the raceway surface 13a of the outer ring 13; and grease 16 charged around the conical roller bearings 14. In the bearing, the inner ring 12 has a flange part, and slide-contacts with the conical rollers 14 at the flange part. The conical roller bearing 11 can be used under a rotation condition that a width of a rotational speed of the conical roller bearing in a use state is equal to 2000 minor wider, and the grease 16 uses mineral oil as base oil as a main component, and has a composition including a complex lithium soap as a thickener.SELECTED DRAWING: Figure 1

    【課題】回転速度の変化が大きい回転条件下での使用において、優れた軸受寿命を有する円すいころ軸受を提供する。【解決手段】円すいころ軸受11は、外周面にテーパ状の軌道面12aを有する内輪12と、内周面にテーパ状の軌道面13aを有する外輪13と、内輪12の軌道面12aと外輪13の軌道面13aとの間を転動する複数の円すいころ14と、円すいころ14の周囲に充填されたグリース16とを備え、内輪12は鍔部を有し、該鍔部において円すいころ14とすべり接触する軸受であって、円すいころ軸受11は、該円すいころ軸受の使用状態における回転速度の幅が2000min−1以上の回転条件で使用可能であり、グリース16が、基油として鉱油を主成分とし、増ちょう剤として複合リチウム石けんを含む組成物である。【選択図】図1
