Specification Brand : iFCOW BulletPoint1 : Long service life time due to low friction, low operation noise. BulletPoint2 : No stick-slip effect, heats up less, reduced drive power required. BulletPoint3 : Low frictional loss, high transmission efficiency. BulletPoint4 : There 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. BulletPoint5 : Ballscrew used the ball movement, so the starting torsion is very small, doesn't appear a sliding motion creeping phenomenon, can ensure accurate positioning.
