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 Worm Gear Jack effectively than other machine screw actuators
No self-locking! Because 
of having less friction, a holding brake is necessary: a engine brake or a spring pressure brake is required.
These worm gear screw jacks are extremely precision and reliability, it can meet all of the necessary protection, cost-efficiency, and sturdiness mandates of your application. High power bronze worm gear is used, the payloads from 0.5T to 100T . A total of 11 sizes can be found, each in a journeying nut version and a basic version.
The screw jacks can be utilized separately or in groups linked with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. In addition they can be powered by different motors: electric, with either AC electric motor or DC motor as well as 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 use trapezoidal screws Tr, because they’re basic, robust and inexpensive. The proportion of screw jacks that use ball screws is however constantly increasing. The reasons for this are mainly their pitch precision, their high efficiency (less power consumption and less heat era) and the higher pitches obtainable, 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 together with the screw shaft. The lifting screw does not slide. It is usually like the linear actuator functioning principle which converts rotational movement into linear motion. Out of this point to understand, an electric linear actuator is certainly 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 certainly more efficient as there are ball bearings between your nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
