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 efficiently than various other machine screw actuators
No self-locking! Due to the lack of friction, a holding brake is essential: a engine brake or a spring pressure brake is necessary.
These worm equipment screw jacks are very precision and reliability, it could meet all the necessary protection, cost-efficiency, and toughness 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 vacationing nut version and a basic version.
The screw jacks can be used separately or in organizations connected with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. They also can be driven by different motors: electric, with either AC engine or DC motor as well as hydraulic or pneumatic motors. All these motion control products could be built in many type jacking program 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’re basic, robust and inexpensive. The proportion of screw jacks that use ball screws is nevertheless Worm Gear Jack constantly increasing. The reason why for this are primarily their pitch precision, their high efficiency (much less power consumption and much less heat era) and the higher pitches available, which permit higher stroke speeds.
A screw jack can add a machine cut lifting nut. Because of this model screw jack, just the bronze nut move combined with the screw shaft. The lifting screw will not slide. It is certainly similar to the linear actuator operating theory which converts rotational movement into linear motion. Out of this stage to understand, an electric linear actuator can be a motorized screw jack.
The screw thread of screw jack can be acme screw and ball screw. So are there few variations of the screw jack. Commonly, machine screw jack and ball screw jack can be found in your engineer task. Compared with acme screw, the ball screw can be more efficient as there are ball bearings between your nut and screw. The anti-friction ball bearing can increase the ball screw efficiency.
