To provide a sealed rolling bearing that is capable of achieving both of low torque performance and high sealing performance. A hub bearing 1 has a seal member 13 that seals a bearing space 9 and is fixed to a fixed side member 12 to be in sliding contact with a rotating side member 15. The seal member 13 has a seal lip that is in sliding contact with the rotating side member 15. Grease is applied to at least one of a sliding contact surface of the seal lip and a sliding contact surface of the rotating side member 15 with which the seal lip is in sliding contact. The grease contains a base oil and a thickener. The kinematic viscosity at 40 °C of the base oil is 6-45 mm2/s. The worked penetration of the grease measured based on JIS K 2220 is 220-320.
