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! Because of having less friction, a keeping brake is essential: a electric motor brake or a spring pressure brake is necessary.
These worm gear screw jacks are very precision and reliability, it can meet all of the necessary basic 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 complete of 11 sizes can be found, each in a journeying nut version and a simple version.
The screw jacks can be utilized separately or in organizations connected with drive Worm Gear Jack shafts, joints, couplings, bevel gearboxes and other mechanical components. In addition they can be powered by different motors: electric, with either AC engine or DC motor and also 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 they are simple, robust and inexpensive. The proportion of screw jacks that make use of 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 generation) and the bigger pitches obtainable, which permit higher stroke speeds.
A screw 
jack can 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 does not slide. It is definitely like the linear actuator working basic principle which converts rotational movement into linear motion. From this point to understand, an electric linear actuator is definitely a motorized screw jack.
The screw thread of screw jack could be acme screw and ball screw. So are there few variations of the screw jack. Commonly, machine screw jack and ball screw jack are available in your engineer task. Compared with 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 increase the ball screw efficiency.
