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 Worm Gear Jack efficiently than other machine screw actuators
No self-locking! Due to the lack of friction, a holding brake is essential: a motor brake or a spring pressure brake is necessary.
These worm gear screw jacks are extremely precision and reliability, it could meet all of the necessary protection, cost-efficiency, and sturdiness mandates of your 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 organizations linked with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. In addition they could be driven by different motors: electrical, with either AC electric motor or DC motor and also hydraulic or pneumatic motors. All these motion control items 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 make use of trapezoidal screws Tr, because they are simple, robust and inexpensive. The proportion of screw jacks that make use of ball screws is however constantly increasing. The reason why for this are mainly their pitch precision, their high efficiency (much less power consumption and less heat era) and the higher pitches available, 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 together with the screw shaft. The lifting screw will not slide. It is certainly similar to the linear actuator operating theory which converts rotational motion into linear motion. From this point to understand, a power 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. 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.
