Servomech Ball Screw Jacks
Linear Actuators South Africa is the official South African partner for Servomech Italy, supplying high-performance ball screw jacks for industrial lifting, positioning, automation and machine-building applications.
Servomech ball screw jacks convert rotary input motion into controlled linear movement using a high-efficiency ball screw system. They are particularly suited to applications requiring higher efficiency, higher linear speeds, accurate positioning and demanding operating cycles.
Depending on the selected series, Servomech ball screw jacks are available for loads from 5 kN up to 800 kN, with solutions for intermittent or continuous-duty operation.
The range includes both Model A travelling-screw and Model B travelling-nut configurations. Ball screw jacks can operate under push or pull load and can also be incorporated into mechanically synchronised multi-jack lifting systems.

Servomech Ball Screw Jack Technical Information
Detailed performance data, dimensions, ball screw combinations, ordering information and configuration options are available in the official Servomech technical documentation.
Selecting the Correct Servomech Ball Screw Jack
Ball screw jack selection depends on more than load capacity alone. The required load, stroke, linear speed, duty cycle, mounting orientation, operating environment and positioning requirements all need to be considered.
For multi-jack lifting systems, the number of lifting points, mechanical arrangement, drive system, connecting shafts and synchronisation requirements should also be evaluated as part of the complete system.
As the official South African partner for Servomech Italy, Linear Actuators South Africa can assist with selecting and configuring a suitable Servomech ball screw jack system.
