Abstract: This improved support assembly for rotating spinning rings of a spinning frame includes a spinning ring holder (20) and a mounting bracket (30) which are each molded of a thermoplastic material having shock-absorbing and vibration-dampening properties. A ball bearing (50) rotatably supports the ring holder (20) on the mounting bracket (30) and the resilient property of the thermoplastic material prevents interference fit of the ball bearing (50). The ring holder (20) extends over and around the upper portion of the ball bearing (50) and felt seals (60, 61) are provided above and below the ball bearing (50) to prevent the entry of lint and the like into the ball bearing (50).
