Worm Gear electric ball screw jack, anti-Rotation and higher pitches available
Translating(traveling screw) and rotating (traveling nut) configurations
Move loads and apply force more effectively than additional machine screw actuators
No self-locking! Due to the lack of friction, a keeping brake is essential: a electric motor brake or a springtime pressure brake is necessary.
These worm equipment screw jacks are very precision and reliability, it could meet all the necessary safety, cost-efficiency, and durability mandates of the application. High strength bronze worm gear is used, the payloads from 0.5T to 100T . A complete of 11 sizes are available, each in a touring nut version and a basic version.
The screw jacks can be utilized separately or in groups linked with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. They also could be powered by different motors: electric, with either AC engine or DC motor in addition to hydraulic or pneumatic motors. Each one of these Worm Gear Jack motion control products 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 use trapezoidal screws Tr, because they are basic, robust and inexpensive. The proportion of screw jacks that use ball screws is however constantly increasing. The reasons for this are mainly their pitch accuracy, their high efficiency (less power consumption and less heat era) and the higher pitches obtainable, which permit higher stroke speeds.
A screw jack can truly add a machine cut lifting nut. Because of this model screw jack, only the bronze nut move along with the screw shaft. The lifting screw does not slide. It is 
certainly like the linear actuator operating basic principle which converts rotational movement into linear motion. Out of this stage to understand, an electric linear actuator is definitely a motorized screw jack.
The screw thread of screw jack can be acme screw and ball screw. So there are few variations 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 more efficient as there are ball bearings between your nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
