[origin: CN104294431A] The invention provides a false twister spindle and a false twister. The false twister spindle comprises a mandrel, a bearing surrounding the mandrel, and a transmission part located on the mandrel, wherein the transmission part and a bearing are spaced in the axial direction of the mandrel. The bearing comprises an outer bearing ring, a first set of rolling elements and a second set of rolling elements, wherein the first set of rolling elements and the second set of rolling elements are located between the outer bearing ring and the mandrel and spaced in the axial direction of the mandrel, the first set of rolling elements are close to the transmission part, the second set of rolling elements are away from the transmission part, a damping ring surrounding the mandrel is installed on the inner circumferential face between the outer bearing ring and the second set of rolling elements, the damping ring is provided with an annular groove with an opening facing the mandrel, and the second set of rolling elements are located between the annular groove and the mandrel. The damping ring is simple in design and can simultaneously achieve the axial damping function and the radial damping function of the mandrel.
