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 various other machine screw actuators
No self-locking! Due to having less friction, a keeping brake is essential: a engine brake or a springtime pressure brake is necessary.
These worm gear screw jacks are extremely precision and reliability, it can meet all the necessary protection, cost-efficiency, and strength 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 simple version.

The screw jacks can be used separately or in organizations linked with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. They also could be driven by different motors: electric, with worm screw jack either AC motor or DC motor as well as hydraulic or pneumatic motors. All 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 reason why for this are primarily their pitch accuracy, 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. Because of this model screw jack, just the bronze nut move together with the screw shaft. The lifting screw does not slide. It can be similar to the linear actuator working basic principle which converts rotational movement into linear motion. From this stage to understand, a power linear actuator is certainly a motorized screw jack.

The screw thread of screw jack can be acme screw and ball screw. So there are few variants of the screw jack. Commonly, machine screw jack and ball screw jack can be found in your engineer task. Compared with acme screw, the ball screw is definitely more efficient as there are ball bearings between the nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
