To provide a sealed rolling bearing capable of achieving both low torque and high sealability.SOLUTION: A hub bearing 1 comprises a seal member 13 that seals a bearing space 9, is fixed to a fixing side member 12, and is in sliding contact with a rotary side member 15. The seal member 13 has a seal lip that is in sliding contact with the rotary side member 15. Grease is applied to at least one of the sliding contact surface of the seal lip and the sliding contact surface of the rotary side member 15 with which the seal lip is in sliding contact. The grease contains a base oil with a kinematic viscosity of 6 mm2/s to 45 mm2/s at 40°C and a thickener, and has a worked penetration of 220 to 320 measured in compliance with JIS K 2220.SELECTED DRAWING: Figure 1

    【課題】低トルク性と高いシール性とを両立できる密封型転がり軸受を提供する。【解決手段】ハブベアリング1は、軸受空間9を密封し、固定側部材12に固定され、回転側部材15に摺接するシール部材13を備え、シール部材13は回転側部材15に摺接するシールリップを有し、シールリップの摺接面、および該シールリップが摺接する回転側部材15の摺接面の少なくとも一方の面にグリースが塗布されており、グリースは、40℃における動粘度が6mm2/s~45mm2/sの基油と増ちょう剤を含み、JIS K 2220に準拠して測定される混和ちょう度が220~320である。【選択図】図1
