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 effectively than various other machine screw actuators
No self-locking! Because of the 
lack of friction, a keeping brake is essential: a motor brake or a springtime Worm Gear Jack pressure brake is required.
These worm equipment screw jacks are extremely precision and reliability, it can meet all the necessary security, cost-efficiency, and sturdiness mandates of the application. High strength bronze worm gear is used, the payloads from 0.5T to 100T . A total of 11 sizes can be found, each in a traveling nut version and a basic version.
The screw jacks can be used separately or in groupings connected with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. In addition they can be driven by different motors: electric, with either AC electric motor or DC motor and also hydraulic or pneumatic motors. Each one of these motion control products can be built-in many type jacking system arrangements or configurations.
Ball screw jacks are normal 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 precision, their high efficiency (less power consumption and much 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, just the bronze nut move combined with the screw shaft. The lifting screw will not slide. It is definitely like the linear actuator operating principle which converts rotational motion into linear motion. From this stage to understand, an electric linear actuator is a motorized screw jack.
The screw thread of screw jack can 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. Compared with acme screw, the ball screw is usually better as there are ball bearings between your nut and screw. The anti-friction ball bearing can raise the ball screw efficiency.
