Worm Gear electrical ball screw jack, anti-Rotation and higher pitches available
Translating(traveling screw) and rotating (traveling nut) configurations
Move loads and apply force more efficiently than various other machine screw actuators
No self-locking! Due to the lack of friction, a holding brake is essential: a motor brake or a spring pressure brake is necessary.
These worm gear screw jacks are very precision and reliability, it can meet all the necessary basic safety, cost-efficiency, and toughness mandates of your application. High power bronze worm gear can be used, the payloads from 0.5T to 100T . A total of 11 sizes can be found, each in a traveling nut version and a simple version.
The screw jacks can be utilized separately or in organizations linked with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. They also can be powered by different motors: electric, with either AC electric motor or DC motor and also hydraulic or pneumatic motors. All these motion Worm Gear Jack control items could be built-in many type jacking system arrangements or configurations.
Ball screw jacks are common where higher speeds and duty cycles are needed. Most screw jacks make use of trapezoidal screws Tr, because they are basic, robust and inexpensive. The proportion of screw jacks that use ball screws is however constantly increasing. The reason why for this are primarily their pitch accuracy, their high efficiency (less power consumption and less heat era) and the bigger pitches offered, which permit higher stroke speeds.
A screw jack can add a machine cut lifting nut. For this model screw jack, just the bronze nut move along with the screw shaft. The lifting screw does not slide. It is like the linear actuator working basic principle which converts rotational movement into linear motion. From this stage to understand, an electric linear actuator is certainly a motorized screw jack.
The screw thread of screw jack could be acme screw and ball screw. So there are few variants of the screw 
jack. Commonly, machine screw jack and ball screw jack are available in your engineer task. Weighed against acme screw, the ball screw is certainly better as there are ball bearings between the nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
