摘要： A scroll thrust bearing having both-end conical rollers are rolling elements, being low in cost, high in precision, large in load capacity, and excellent in durability. A plurality of both-end conical rollers are held rotatably between a pair of bearing plates, and the relation of the scroll swirl radius (R) of both-end conical roller and the dimension (H) between opposite tracks of the both bearing plates is set in a range of 1
