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! Due to the lack of friction, a keeping brake is necessary: a motor brake or a spring pressure brake is required.
These worm gear screw jacks are extremely precision and reliability, it can meet all the necessary security, cost-efficiency, and toughness mandates of your application. High power bronze worm gear is used, the payloads from 0.5T to 100T . A 
complete of 11 sizes are available, each in a touring nut version and a basic version.
The screw jacks can be used separately or in groups Worm Gear Jack connected with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. In addition they could be driven by different motors: electrical, with either AC engine 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 make use of 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 primarily their pitch accuracy, their high efficiency (much less power consumption and less heat era) 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 along with the screw shaft. The lifting screw does not slide. It is usually like the linear actuator operating principle which converts rotational motion into linear motion. Out of 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 project. 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 raise the ball screw efficiency.
