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! Because of having less friction, a keeping brake is necessary: a Worm Gear Jack engine brake or a springtime pressure brake is required.
These worm equipment screw jacks are very precision and reliability, it could meet all of the necessary security, cost-efficiency, and durability 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 traveling nut version and a simple version.
The screw jacks can be utilized separately or in groupings connected with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. In addition they could be driven by different motors: electric, with either AC motor or DC motor in addition to hydraulic or pneumatic motors. Each one of these motion control products can 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 use trapezoidal screws Tr, because they are simple, robust and inexpensive. The proportion of screw jacks that make use of ball screws is however constantly increasing. The reasons for this are primarily their pitch accuracy, their high efficiency (much less power consumption and less heat era) and the higher pitches offered, 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 combined with the screw shaft. The lifting screw will not slide. It is like the linear actuator functioning basic principle 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 can be found in your engineer project. Compared with acme screw, the ball screw is more efficient as there are ball bearings between the nut and screw. The anti-friction ball bearing can raise the ball screw efficiency.
