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 electric motor brake or a spring pressure brake is necessary.
These worm equipment screw jacks are very precision and reliability, it could meet all of the necessary security, cost-efficiency, and strength mandates of your 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 vacationing nut version and a simple version.
The screw jacks can be utilized separately or in groups linked with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. In addition they could be powered by different motors: electric, with either AC motor or DC motor along with hydraulic or pneumatic motors. All 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 worm screw jack 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 nevertheless constantly increasing. The reason why for this are primarily their pitch precision, their high efficiency (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. Because of this model screw jack, only the bronze nut move along with the screw shaft. The lifting screw does not slide. It is definitely like the linear actuator working theory which converts rotational motion into linear motion. From this stage to understand, a power linear actuator is usually a motorized screw jack.
The screw thread of screw jack could be acme screw and ball screw. So there are few variations of the screw jack. Commonly, 
machine screw jack and ball screw jack are available in your engineer project. Compared with acme screw, the ball screw is definitely better as there are ball bearings between your nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
