PURPOSE:To enable to transmit a thrust load to an external ring by forming a ring-shaped groove between a small diameter half ring and a large diameter half ring fitted in each other, and positioning a ring-shaped projection provided on the external surface of inner ring in the said ring-shaped groove to divide balls into 2 rows. CONSTITUTION:A small diameter half ring 2a and a large diameter half ring 2b comprising an external ring 2 is incorporated by fitting a ring-shaped projection 2a1 and a ring-shaped concave groove 2b1 positioned opposite to face each other to be engaged together. A ring-shaped projection 1a provided in the middle of exterior of inner ring 1 projects in a ring-shaped groove G formed by side walls 2a2 and 2b2 facing each other in the external ring 2, and divides many steel balls 3 contained in the ring-shaped groove G into 2 rows right and left. Circular guide faces 1a1 conforming to the ball 3 is formed on the both sides of the ring-shaped projection 1a and also a circular guide face 2a3 is formed on the inside of side wall 2a2 of small diameter half ring 2a. |
