Electric worm gear ball screw jacks of high precision
1. Ball Screw Jack Picture & Function:
Theball screw jackscan be employed for lifting, pulling, moving, aligning any kind of load with a perfect synchronism, which is difficult to obtain by means of other handling devices.The ball screw jacks are suitable for high services as well as for a very rapid, quick and precise positioning.
Ball Screw Jacksuse a ball screw and nut made from hardened alloy steel with bearing balls carrying the load between nut & screw. This rolling action reduces the friction between nut and screw, permitting smooth and efficient load movement that requires approximately 1/3 less torque than a machine screw jack with the same load.
2. Ball Screw Jack’s Advantages:
The ball screw jacks are preferred for:
• Long travel lengths
• Long, predictable life
• High duty cycles
• Oscillating motion

4. How to Choose aScrew Jack?Some questions you need answer pls.
Q1: The capacity isto load? KG (it means how many Kg or Tons the screw jack need to lift or drop?)
The stroke is ? mm (it means the screw shaft length, such as 500mm)
The lifting speed is ? mm/second (it means how much time you want to use to finish the stroke? Such as I want to use 20 seconds to finishthe500mm strokethen can come out the speed is 25mm/s )

Q2:Which the screw topyou need?Answer: I need (A B C D E F).
Q3:Manual type(Hand wheeldriven) or electric motor driven type?Answer: I need type.
Q4:Screw movement (screw travelling up and down when working) or Nut movement (the nuttravelling up and down when working)? Upright orInverted? Answer: I need (A B E F)
Q5:Screw jacks linkage
Do you need two or above two sets screw jacks to linkage, if yes pls seethe belowscrew jacks linkage scheme, if no pls ignore this.
Answer: 1. No need 2. Need,sets (2 /3 /4 /8 or othersets) screw jacks to linkage, ( I /T / L / H / U) )type ( Or you can mark it out on the below screw jacks linkage scheme picture).
For example, a 4-sets linkage H type ( without screw in this picture) as followIing:
