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 other machine screw actuators
No self-locking! Because of the lack of friction, a keeping brake is essential: a electric motor brake or a springtime pressure brake is necessary.
These worm equipment screw jacks are very precision and reliability, it can meet all of the necessary basic safety, cost-efficiency, and strength 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 journeying nut worm screw jack version and a basic version.

The screw jacks can be used separately or in organizations connected with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. In addition they could be powered by different motors: electric, with either AC electric motor or DC motor along with hydraulic or pneumatic motors. Each one of these motion control products could 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 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 however constantly increasing. The reasons for this are primarily their pitch precision, their high efficiency (less power consumption and much 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, only the bronze nut move combined with the screw shaft. The lifting screw will not slide. It can be like the linear actuator operating basic principle which converts rotational movement into linear motion. From this stage to understand, an electric linear actuator is usually a motorized screw jack.

The screw thread of screw jack could 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 definitely more efficient as there are ball bearings between your nut and screw. The anti-friction ball bearing can raise the ball screw efficiency.
