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 necessary: a electric motor brake or a springtime pressure brake is required.
These worm gear screw jacks are extremely precision and reliability, it can meet all the necessary protection, 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 are available, each in a journeying nut version and a simple version.
The screw jacks can be utilized separately or in groupings connected with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. 
They also can be powered by different motors: electric, with either AC motor or DC motor in addition to hydraulic or pneumatic motors. Each one of these motion control products can 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 use trapezoidal screws Tr, because Worm Gear Jack they’re simple, robust and inexpensive. The proportion of screw jacks that use ball screws is nevertheless constantly increasing. The reasons for this are mainly their pitch accuracy, their high efficiency (much less power consumption and less heat era) and the bigger pitches offered, which permit higher stroke speeds.
A screw jack can truly add a machine cut lifting nut. For this model screw jack, just the bronze nut move together with the screw shaft. The lifting screw does not slide. It is usually similar to the linear actuator functioning theory 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 are there 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 better as there are ball bearings between the nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
