Worm Gear electric ball screw jack, anti-Rotation and worm screw jack higher pitches available
Translating(traveling screw) and rotating (traveling nut) configurations
Move loads and apply force more effectively than additional machine screw actuators
No self-locking! Due to the lack of friction, a keeping brake is essential: a motor brake or a springtime pressure brake is required.
These worm gear screw jacks are very precision and reliability, it can meet all the necessary safety, cost-efficiency, and durability 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 utilized separately or in groupings connected with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. They also can be powered 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 program 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’re simple, robust and inexpensive. The proportion of screw jacks that make use of ball screws is nevertheless constantly increasing. The reasons for this are mainly their pitch precision, their high efficiency (much less power consumption and less heat era) and the bigger pitches offered, which permit higher stroke speeds.
A screw jack can truly add a machine cut lifting nut. For this model screw jack, only the bronze nut move combined with the screw shaft. The lifting screw will not slide. It is certainly like the linear actuator operating theory which converts rotational motion into linear motion. From this stage to understand, a power 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. Compared with acme screw, the ball screw can be more efficient as there are ball bearings between your nut and screw. The anti-friction 
ball bearing can boost the ball screw efficiency.
