Patent ID: 7866891

Claim:
A two-split outer ring having a raceway surface for receiving rollers on an inner peripheral surface, the outer ring being split into two split parts in a circumferential direction and formed in a cylindrical shape by assembling the split parts with each other, wherein the split parts are formed by splitting a cylinder material, which constitutes the two-split outer ring, along a splitting line that is meandering or inflected with a predetermined vibration width with respect to an axial direction, and front end portions of splitting surfaces formed at both ends in the circumferential direction are formed such that the split parts form circular arcs having a central angle greater than 180 degrees as viewed from an axial direction, and wherein in the inner peripheral surfaces of the split parts, a minimum gap of the opposing inner peripheral surfaces extending from both ends of a certain circular arc portion having a central angle of 180 degrees as viewed from the axial direction to the respective front ends is equal to or greater than the inner diameter of the split parts.
