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 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 required.
These worm equipment screw jacks are extremely precision and reliability, it could meet all of the Worm Gear Jack necessary security, cost-efficiency, and toughness mandates of your application. High strength bronze worm gear can be used, the payloads from 0.5T to 100T . A total of 11 sizes can be found, each in a vacationing nut version and a basic version.

The screw jacks can be used separately or in organizations linked with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. In addition they can be driven by different motors: electrical, with either AC engine 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 nevertheless constantly increasing. The reasons for this are mainly their pitch precision, their high efficiency (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. Because of this model screw jack, just the bronze nut move along with the screw shaft. The lifting screw will not slide. It is usually like the linear actuator working principle which converts rotational motion into linear motion. From this stage to understand, an electric linear actuator is a motorized screw jack.

The screw thread of screw jack could be acme screw and ball screw. So are there few variations of the screw jack. Commonly, machine screw jack and ball screw jack are available in your engineer task. Compared with acme screw, the ball screw is definitely more efficient as there are ball bearings between the nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
