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 efficiently than various other machine screw actuators
No self-locking! Because of having less friction, a holding brake is essential: a motor brake or a spring pressure brake is required.
These worm equipment screw jacks are very precision and reliability, it could meet all the necessary protection, cost-efficiency, and strength mandates of the application. High power bronze worm gear is used, the payloads from 0.5T to 100T . A complete of 11 sizes can be found, each in a journeying nut version and a simple version.

The screw jacks can be used separately or in Worm Gear Jack 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 engine or DC motor in addition to hydraulic or pneumatic motors. Each one of these motion control products 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 however constantly increasing. The reasons for this are mainly 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 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. Compared with acme screw, the ball screw is definitely better as there are ball bearings between your nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
