Beschreibung
Zusammenfassung:	A high speed rolling bearing of a long life, having a low rotation torque and a small leakage amount of a grease, is provided. The high speed rolling bearing comprises retainers disposed so as to surround respective rolling elements between an outer member and an inner member thereof, and the respective rolling elements roll against a first contact face which is a contact face thereof with the outer member as well as a second contact face which is a contact face thereof with the inner member. The retainers are made of a polyamide, and the retainers made of the polyamide retains a grease composition, composed of a thickener and a base oil composed of a synthetic hydrocarbon oil having kinematic viscosity at 40 DEG C in a range of 50 to 70 mm /s, and containing 3 to 6 mass % of hydrocarbon molecules containing 28 to 32 carbon atoms.
