摘要

The body (1) has a roll (2) including a circular middle recess (5), an outer mantle surface (6a) and an inner mantle surface (6i). A cylinder (3) including an outer jacket (7) is arranged in the middle recess, where one of front surfaces of the cylinder is formed as spherical. A set of hollow rolls (4) is arranged between the outer jacket of the cylinder and the inner mantle surface. The outer mantle surface exhibits a parallel, shaped or sloped characteristic with respect to a rotational axis of the body. An independent claim is also included for a roller bearing including a bearing inner ring.
