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 other machine screw actuators
No self-locking! Due to having less friction, a holding brake is necessary: a electric motor brake or a spring pressure brake is required.
These worm equipment screw jacks are very precision and reliability, it could meet all the necessary safety, cost-efficiency, and durability mandates of your application. High power bronze worm gear can be used, the payloads from 0.5T to 100T . A complete of 11 sizes are available, each in a journeying nut version and a simple version.
The screw jacks can be used separately or in groupings linked with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. In addition they can be powered by different motors: electrical, with either AC motor or DC motor along with hydraulic or pneumatic motors. Each one of these motion control products could be built-in many type jacking system 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’re simple, robust and inexpensive. The proportion of screw jacks that use ball screws is nevertheless constantly increasing. The reasons for this are primarily their pitch precision, their 
high efficiency (less power consumption and much less heat generation) and the bigger 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 along with the screw shaft. The lifting screw does not slide. It is definitely like the linear actuator functioning principle which converts rotational motion into linear motion. Out of 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 are there few variations of the screw jack. Commonly, machine screw jack and ball screw jack can be found in your engineer project. Compared with acme screw, the ball screw can be better as there are ball bearings worm screw jack between the nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
