<p>A stabilizing bearing designed to selectively operate to provide lateral support to a small diameter drive shaft (18) used in a small ultracentrifuge. The stabilizing bearing (40, 42) is preferably operated by the use of a solenoid (38) to move the bearing (40) into place to provide lateral support to the thin drive shaft (18) when it might otherwise flex at low speeds, causing vibration and possible detrimental effects to the desired centrifugal separation of the fluid sample in the rotor. The activation of the stabilizing bearing is automatic in response to a specified speed parameter of the drive shaft.</p> |
