Abstract
A robot includes a base, at least one roller bearing having an inner hub supported to the base and an outer hub rotated about the inner hub, a spacer contacting the outer hub, a spin body to which the spacer is attached, and a spin mechanism coupled to the spin body to rotate the spin body. The spacer separates the spin body from the roller bearing between the spin body and the roller bearing. A surface hardness of the spacer is greater than a surface hardness of the spin body.
