The mechanical jack (so-called screw jack) is a specific type of linear actuator designed to handle very high loads in lifting and positioning applications. ATLANTA solutions focus on maximizing speed and force, while maintaining high precision and a compact design.
The ATLANTA servoactuator is the combination of an ATLANTA low-backlash precision servo worm gearbox with an adequately sized, optimized, and manufactured ball screw. This union results in countless advantages that are not normally found in screw jacks on the market, whether they are trapezoidal screw or “classic” ball screw types.
Integrated servo worm gearbox
This design reduces inertia, improving the controllability and dynamism of the system compared to standard screw jacks. Low circumferential backlash is essential for precise positioning.
The integration of the gearbox and the non-inline design between the motor and the ball screw allow for a compact and space-saving layout.
The servo worm gearboxes are optimized to work with servo motors with input speeds up to 6000 rpm, which allow very high linear speeds (up to 666 mm/s in the standard version), while maintaining significant load capacities.
ATLANTA uses special ball screws, appropriately sized and manufactured, with static and dynamic load capacities far superior to the standard.
Furthermore, the standard axial backlash is only 0.03mm or zero (with preload), which is fundamental for positioning precision and repeatability. The resulting lead error is 23µm/300mm.
The ATLANTA solutions are suitable for continuous operation (up to 100% duty cycle), thanks to the low heat generation determining a clear advantage compared to the most widespread screw jacks on the market.
Versatility as a key competence
ATLANTA proposes solutions with a completely closed and guided cylinder for maximum protection and for use in ATEX zones or in the presence of vacuum, in addition to the classic versions with rotating screw or telescopic rod.
ATLANTA has long been employed in numerous food-grade or high-temperature applications and can also integrate additional limit switches.
We are the tailors for your challenge
ATLANTA’s know-how is expressed not only in standardized servoactuators, but above all in customized and tailor-made solutions.
When a standard ATLANTA servoactuator is not sufficient and the application requires a completely ad hoc solution, ATLANTA itself makes its engineering, process, and production resources available to realize what was previously just a challenging idea.
