You can prevent a ball screw from falling by using some adhesive on the ball screw connection. This can help to ensure that the ball stays on.
Ball screw actuators are used in industrial equipment where precision motion is required. The ball screw assembly rotates the part using the actuator as a pivot.
There are several uses for a balll screw jack. Ball screw jack assemblies use small balls to roll between the nut and the lifting ball screw. It creates less friction and increases use life.

I say i am a ball on fire in table tennis :d
A ball screws measurements are determined by many things. For instance, a 1, 3, 4 foot ball screw has the nominal diameter of 3/8’s, the nominal root diameter of .300 inches, and is .125 lead/reverse. A ball screw is a mechanical device used in the translation of rotating motion to a linear motion. This is done by a ball screw, with very little friction. A ball screw can reduce friction and operate with preload. This is effective in the elimination of the backlash between rotation and linear motion.

It doesn't look like used ball screw jacks are plentiful at the moment. Here are some suppliers that sell new ones: http://www.thomasnet.com/products/jacks-ball-screw-41400409-1.html If you looking to buy a used ball screw jack, then I suggest you vist www.directindustry.com. This should help you solve your answer.
If a ball screw assembly comes loose, it can be extremely dangerous as a threaded shaft provides a spiral raceway for ball bearings which act as a precision screw. When loosened, the two objects which are being held together by the ball screw assembly could dangerously fly open and injur anyone within a short distance.
The choice of ball color is made according to the table color and its surroundings. For example, a white ball is easier to see on a green or blue table than it is on a grey table.
There are many websites where you can purchase ball screw nuts. A few of these sites include www.homedepot.com, www.lowes.com, and even www.amazon.com.
No the ball must touch your side of the table before you can hit it
