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! Because of the lack of friction, a holding brake is essential: a electric motor brake or a spring pressure brake is necessary.
These worm equipment screw jacks are very precision and reliability, it could meet all the necessary protection, cost-efficiency, and durability mandates of your application. High strength bronze worm gear is used, the payloads from 0.5T to 100T . A complete of 11 sizes are available, each in a traveling nut version and a simple version.

The screw jacks can be utilized separately or in groups connected with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. In addition they can be powered 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 program arrangements or configurations.
Ball screw jacks are normal where higher Worm Gear Jack speeds and duty cycles are needed. Most screw jacks make use of trapezoidal screws Tr, because they’re basic, robust and inexpensive. The proportion of screw jacks that make use of ball screws is nevertheless constantly increasing. The reasons for this are mainly their pitch accuracy, their high efficiency (much less power consumption and much less heat era) and the bigger pitches available, which permit higher stroke speeds.

A screw jack can add a machine cut lifting nut. For this model screw jack, just the bronze nut move along with the screw shaft. The lifting screw will not slide. It is usually similar to the linear actuator functioning basic principle which converts rotational movement into linear motion. Out of this stage to understand, a power linear actuator is usually a motorized screw jack.

The screw thread of screw jack could 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 project. Compared with acme screw, the ball screw can be more efficient as there are ball bearings between the nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
