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 efficiently than various other machine screw actuators
No self-locking! Due to the lack of friction, a holding brake is essential: a motor brake or a springtime pressure brake is required.
These worm equipment screw jacks are extremely precision and reliability, it can meet all of the necessary safety, cost-efficiency, and durability mandates of your application. High strength bronze worm gear can be used, the payloads from 0.5T to 100T . A total of 11 sizes are available, each in a journeying nut version and a basic version.
The screw jacks can be used separately or in organizations linked with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. They also can be driven by different motors: electric, with either AC electric motor or DC motor and also hydraulic or pneumatic worm screw jack motors. All 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 they’re basic, 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 accuracy, their high efficiency (less power consumption and much less heat era) and the higher pitches offered, which permit higher stroke speeds.
A screw jack can add a machine cut lifting nut. For this model screw jack, just the bronze nut move along with the screw shaft. The lifting screw does not slide. It 
is certainly like the linear actuator functioning basic principle which converts rotational motion into linear motion. From 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 there are 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 can be more efficient as there are ball bearings between the nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
