Specification Brand : Wisoqu 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 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 , can ensure accurate positioning Color : #754 ExternallyAssignedProductIdentifier : 7635667147992 IncludedComponents : No ItemName : Ball Screw 300mm, Ball Screw 300mm Ball Screw Backlashfree Without Lateral End Supports, Screw Pitch 4mm, Screw Diameter 12 Mm, 300mm Ball Screw ItemPackageDimensions_Height : 5 centimeters ItemPackageDimensions_Length : 33 centimeters ItemPackageDimensions_Width : 6 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : ball-screws Manufacturer : Wisoqu Material : Metal ModelName : Wisoquk20wnfbe6i ModelNumber : Wisoquk20wnfbe6i NumberOfItems : 1 PartNumber : Wisoquk20wnfbe6i ProductDescription : 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 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.
