Summary:PROBLEM TO BE SOLVED: To provide a rolling bearing that discovers a new index capable of providing low torque of a bearing irrespective of sorts or combination of base oil and a thickening agent, and to provide a rolling bearing that satisfies the index and has low torque.SOLUTION: A rolling bearing is encapsulated with a lubricant composition that contains base oil, a thickening agent and an additive agent and has a value of 1 to 20.20.83 that is obtained by dividing yield stress with shearing force at a shearing speed of 10000 s.SELECTED DRAWING: Figure 1 【課題】基油や増ちょう剤の種類や組合せによらず、軸受の低トルク化を実現できる新たな指標を見出すとともに、その指標を満足して低トルク化を図った転がり軸受を提供する。【解決手段】基油、増ちょう剤及び添加剤を含み、降伏応力を、せん断速度１００００ｓ−１でのせん断応力で除した値が１〜２０．２０．８３である潤滑剤組成物を封入した転がり軸受。【選択図】図１
