Abstract
An improved device for supporting a spindle of an open-end spinning apparatus is provided with a ring shaped resiliently yieldable member rigidly disposed in a space between a bearing supporting the spindle and an inside cylindrical wall of a bushing member, and an additional ring shaped member rigidly disposed in the above-mentioned space separately from the resiliently yieldable member. To prevent accumulation of heat in the spindle, a plurality of grooves are formed on the peripheral surface of the bearing and/or inside surface of the resiliently yieldable member, and/or the additional member, respectively.
