摘要
A rotor drive shaft assembly for use in a centrifugation system. The rotor drive shaft has a bearing material configured as a sleeve and mounted on the inside wall of a spindle hub with a clearance existing between the sleeve and a housing that surrounds the lower base of the shaft. When the rotor and hub experience radial displacement at a critical speed, the sleeve makes contact with the housing in order to limit further radial displacement. Alternatively, the sleeve can be mounted on the outside of the housing with the clearance existing between the sleeve and the spindle hub, with the sleeve making contact with the spindle hub at the critical speed in order to limit further radial displacement. In another embodiment, a support tube is provided which surrounds the lower portion of the shaft with a clearance existing between the shaft and the support tube. When the shaft experiences radial displacement at the critical speed, the shaft makes contact with the support tube which limits further radial displacement.
