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 effectively than other machine screw actuators
No self-locking! Due to the lack of friction, a keeping brake is necessary: a engine brake or a springtime pressure brake is necessary.
These worm equipment screw jacks are extremely precision and reliability, it can meet all of the Worm Gear Jack necessary basic safety, cost-efficiency, and durability mandates of your application. High strength bronze worm gear can be used, the payloads from 0.5T to 100T . A complete of 11 sizes can be found, each in a traveling nut version and a basic version.

The screw jacks can be utilized separately or in groupings linked with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. They also can be driven by different motors: electrical, with either AC electric motor or DC motor as well as hydraulic or pneumatic motors. All these motion control items can 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 are simple, robust and inexpensive. The proportion of screw jacks that use ball screws is nevertheless constantly increasing. The reason why for this are primarily their pitch accuracy, their high efficiency (less power consumption and less heat generation) and the higher pitches obtainable, 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 along with the screw shaft. The lifting screw will not slide. It is similar to the linear actuator working theory which converts rotational movement into linear motion. Out of this point to understand, an electric 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 are available in your engineer project. Weighed against acme screw, the ball screw is more efficient as there are ball bearings between your nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
