Specification Brand : Gearwell 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 Color : #755 Department : Unisex Adult ExternallyAssignedProductIdentifier : 8055476884526 IncludedComponents : No ItemName : Gearwell 400mm Rolled Ball Screw SFU1204 Anti Backlash Linear Motion Metal Ball Screw Nut Without Side End Supports for CNC Machines and 3D Printers ItemPackageDimensions_Height : 4 centimeters ItemPackageDimensions_Length : 40 centimeters ItemPackageDimensions_Width : 8 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : ball-screws Manufacturer : Gearwell Material : Metal ModelName : Gearwellp54ia3smog ModelNumber : Gearwellp54ia3smog MountingType : Side Mount NumberOfBoxes : 1 NumberOfItems : 1 NumberOfPieces : 1 PartNumber : Gearwellp54ia3smog ProductDescription : Features: Long service life time due to low friction, low operation noise.
