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 additional machine screw actuators
No self-locking! Due to the lack of friction, a holding brake is necessary: a electric motor brake or a spring pressure brake is necessary.
These worm gear screw jacks are extremely precision and reliability, it could meet all the necessary worm screw jack security, cost-efficiency, and durability mandates of the application. High power 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 basic version.

The screw jacks can be used separately or in groups linked with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. They also can be powered by different motors: electric, with either AC engine or DC motor in addition to 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 cycles are needed. Most screw jacks make use of trapezoidal screws Tr, because they are basic, 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 accuracy, their high efficiency (much less power consumption and less heat generation) and the bigger pitches available, 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 along with the screw shaft. The lifting screw does not slide. It is similar to the linear actuator operating theory which converts rotational motion into linear motion. From this point to understand, an electric linear actuator is usually 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 usually better as there are ball bearings between the nut and screw. The anti-friction ball bearing can increase the ball screw efficiency.
