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 required.
These worm equipment screw jacks are very precision and reliability, it can meet all the necessary 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 vacationing nut version and a simple version.

The screw jacks can be used separately or in groupings connected with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. They also could be worm screw jack powered by different motors: electrical, with either AC electric motor or DC motor and also 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 are simple, robust and inexpensive. The proportion of screw jacks that use ball screws is however constantly increasing. The reasons 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 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 usually similar to the linear actuator working basic principle which converts rotational motion into linear motion. Out of this point to understand, an electric 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 are available in your engineer task. Weighed against acme screw, the ball screw is certainly better as there are ball bearings between your nut and screw. The anti-friction ball bearing can raise the ball screw efficiency.
