1Long service life time due to low friction, low operation noise 2No stickslip effect, heats up less, reduced drive power required 3Low frictional loss, high transmission efficiency 4There are a lot of balls rolling movement between the screw shaft and ballscrew nut, they are able to get a higher efficiency of movement. Helpful in saving 5Ballscrew used the ball movement, so the starting torsion is very small, doesn't appear a sliding motion creeping phenomenon, can ensure accurate positioning
