This paper deals with development by way of trial for a new pivot bearing having three degrees of freedom. The idea of this pivot bearing is based on a continuous velocity joint (CVJ). At first, I achieved the 3 degrees of freedom using ball bearings. But it was big size compared with a bearing with 2 degrees of freedom. By improving internal structure, it was achieved that the 3 degrees of freedom by size the same as a 2 degree of freedom bearing.
