| 20 Ton Ball Screw Jacks Configurations: Upright Translating Ball Screw Jack, Inverted Translating Ball Screw Jack, Upright Rotating Ball Screw Jack, Inverted Rotating Ball Screw Jack, Double Clevis Ball Screw Jack, Upright Anti-rotation Ball Screw Jack, and Inverted Anti-rotation Ball Screw Jack. It is used only when the load to be moved (actuated) may rotate, i.e. the screw is unguided and does not prevent rotation. The anti-rotation device consists of a square steel tube which guides the movement of a square aluminium bronze guide block fitted to the end of the ball screw. The guide block also acts as a stop nut. | |||||||||

Product Description
Classic Ball Screw Jack 20 Ton-63x10-Ball Screw. Ball Screw Jack is a highly efficient jack for high speed, high frequency operations. Major components include accurate ball screw and high precision worm gear. jacton ball screw generates high efficiency and its compact drive unit produces high power. Compared to the linear power jacks machine screw type, its high efficiency allows easier high speed drive. Long and predictable ball screw life. The higher efficiency of the ball screw drive also permits a longer duty cycle. Stop collar is A Prevents the screw from being removed from the jack gearbox. Fitted as standard on ball screw versions.
Main Features
* Maximum static load capacities 20 ton (20000kg).
* High precision ball screw sizes 63x10, custom high lead 63x20.
* Two gear ratios: high ratio 8:1, slow ratio 24:1, for high and slow linear speeds (up to 3500 mm/min).
* Custom stroke length of ball screw, maximum stroke 4000 mm in compression load, 5000 mm in tension load.
* Basic designs: Translating screw, Anti-rotation screw, and Rotating screw.
* Upright or Inverted mounting. Available in tension or compression loads.
* Ball screw end fittings: top plate, clevis end, threaded end, plain end, fork head and rod end.
* Standard with single lead ball screw, custom double or high lead ball screw which offers increased travel speed. Both of them require a brake or external locking device to hold position.
* Power source: hand wheel is not recommended, must be brake motor.
* Can be applied either individually use or combined into a exactly synchronized lifting system(multiple jack systems), linked by connecting shafts, bevel gearboxes, couplings, electric motors, gear reducers, limit switches and pillow blocks etc.
* Can be used as alternatives to hydraulic and pneumatic systems.
* High accuracy, high efficiency, high performance, high duty cycle, low backlash, long service life, and uniform lifting speed.
