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! Due to having less friction, a holding brake is essential: a motor brake or a spring pressure brake is required.
These worm equipment screw jacks are extremely precision and reliability, it could meet all of the necessary safety, cost-efficiency, and sturdiness mandates of your application. High power bronze worm gear can be used, the payloads from 0.5T to 100T . A complete of 11 sizes are available, each in a journeying nut version and a simple version.
The screw jacks can be utilized separately or in groups connected with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. They also could be driven by different motors: electrical, with either AC electric motor or DC motor and also hydraulic or pneumatic 
motors. Each one of these motion control products could 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 use trapezoidal screws Tr, because they’re 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 less heat generation) and the bigger pitches available, which permit higher stroke speeds.
A screw jack can truly add a machine cut lifting nut. For this model screw jack, only the bronze nut move combined with the screw shaft. The lifting screw does not slide. It can be like the linear actuator functioning theory which converts rotational motion into linear motion. From this stage to understand, an electric linear actuator is usually a motorized screw jack.
The screw thread of screw jack can be acme screw and ball screw. So are there few variants of the screw jack. Commonly, machine screw jack and ball screw jack can be found in your engineer project. Compared with acme screw, the ball screw is certainly better as there are ball bearings between your nut and screw. The anti-Worm Gear Jack friction ball bearing can raise the ball screw efficiency.
