Features 1、Long service life time due to low friction, low operation noise 2、No stick‑slip effect, heats up less, reduced drive power required 3、Low frictional loss, high transmission efficiency 4、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 5、Ballscrew used the ball movement, so the starting torsion is very small, doesn't appear a sliding motion creeping phenomenon, can ensure accurate positioning Specification Features: Long service life time due to low friction, low operation noise. No stick-slip effect, heats up less, reduced drive power required. Low frictional loss, high transmission efficiency. 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. Ballscrew used the ball movement, so the starting torsion is very small, doesn't appear a sliding motion creeping phenomenon, can ensure accurate positioning. Specifications: Total Length: 1000mm / 39.374inch Screw diameter: 16mm / 0.63inch Screw pitch: 5mm / 0.2inch Max Speed : 16000RPM Weight: Approx. 1504g Package Included: 1 x Rolled Ballscrew (1000mm) Note: Please allow 1-5cm error due to manual measurement.
