PROBLEM TO BE SOLVED: To provide a grease sealed bearing which materializes improvement of bearing performance by improving lubricating conditions of grease and increasing seizure life. SOLUTION: The grease sealed bearing 10 is provided with an inner ring 11 on whose outer diameter surface the inner ring raceways 11a, 11b are formed, an outer ring 12 on whose inner diameter surface the outer ring raceways 12a, 12b are formed, a crown-shaped holder 15 arranged so as to be relatively freely rotatable to the inner and outer rings 11, 12, and balls 13 freely turnably held respectively in a plurality of pockets 14 provided to the crown-shaped holder 15. The bearing is lubricated by grease sealed around the ball 13. The inner ring raceways 11a, 11b and outer ring raceways 12a, 12b are arranged in the position deviated to an opening side of the pocket 14 of the crown-shaped holder 15 with respect to the center line B in the axial direction of the bearing 10.
