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 effectively than additional machine screw actuators
No self-locking! Due to having less friction, a keeping brake is necessary: a electric motor brake or a springtime pressure brake is necessary.
These worm gear screw jacks are very precision and reliability, it could meet all of the necessary worm screw jack security, cost-efficiency, and toughness mandates of your application. High power bronze worm gear can be used, the payloads from 0.5T to 100T . A total of 11 sizes are available, each in a touring nut version and a simple version.
The screw jacks can be used separately or in organizations linked with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. They also 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 items could 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 make use of 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 reason why for this are mainly their pitch accuracy, their high efficiency (much less power consumption and less heat era) and the higher pitches available, 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 
will not slide. It can be similar to the linear actuator functioning principle which converts rotational movement into linear motion. Out of this point to understand, a power linear actuator is usually a motorized screw jack.
The screw thread of screw jack can be acme screw and ball screw. So are there few variants 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 the nut and screw. The anti-friction ball bearing can increase the ball screw efficiency.
