To provide a rolling bearing capable of suppressing reduction in a supply amount of a lubrication material to a bearing space, without increasing a dimension in a width direction.SOLUTION: A rolling bearing comprises an annular seal member 17. The annular seal member 17 is arranged between an outer ring and an inner ring so as to close a bearing space sandwiched between the outer ring and the inner ring. A mark 19M is displayed on the surface of the seal member 17 by laser marking. In the bearing space, a lubrication material is enclosed. A volume of a lubrication material enclosed in the bearing space is 20% or more of a total bearing space volume of the bearing space, and is less than a static space volume of the bearing space.SELECTED DRAWING: Figure 2

    【課題】幅方向寸法を大きくすることなく、軸受空間への潤滑材の供給量の減少を抑制可能な転がり軸受を提供する。【解決手段】転がり軸受は、環状のシール部材17を備える。環状のシール部材17は外輪と内輪とに挟まれた軸受空間を閉じるように外輪と内輪との間に配置される。シール部材17の表面にはレーザマーキング加工によりマーク19Mが表示されている。軸受空間には潤滑材が封入されている。軸受空間に封入される潤滑材の体積は、軸受空間の軸受全空間容積の20%以上であり、軸受空間の静止空間容積以下である。【選択図】図2
