A new generation of screw jacks

Freeing up resources thanks to efficiency and energy savings ensures a rapid return on technological investments also by containing management costs. The adoption of green solutions is good for the environment, but also for the financial statements of companies.

The Servomech Group moves in this direction, which since its establishment in 1989 has been characterized by its ability to be ahead of its time, soon becoming a point of reference in the design and construction of mechanical linear actuators with acme and ball screw, ball screw jacks, acme screw jacks, bevel gearboxes, ball screws and nuts.

On this front, the company has conducted numerous successful interventions in recent years, thus leaving a tangible sign of its know-how in important application cases, thanks to a totally internal management of production, design and controls inside its production facility in Bologna, for a Made in Italy with high technological value.

An innovative patended design for ball screw jacks

A confirmation of the ability to innovate that distinguishes Servomech are the greater performance in terms of efficiency, load capacity, durability and rigidity of Servomech MA BS Model A Series ball screw jacks with travelling screw, thanks to an innovative patented design that after a decade still proves to be innovative, establishing itself on the market for uniqueness and competitiveness.

Available in 8 different sizes – load capacity from 5 to 350 kN, ball screw diameter from 16 to 120 mm, input speed up to 3000 rpm, oil lubricated gearbox, continuous duty cycle – ball screw jacks MA BS Model A Series are the result of a path that, for decades, has been nourished by research and experimentation and which has a competitive factor as well as a guarantee in the totally internal production made by Servomech.

The native integration of the gearbox components and the ball screw nut, designed and produced inside the Servomech factory, ensure, together with the advanced design, a significant weight reduction, eliminating unnecessary material to the advantage of costs. The result is not only superior performance and greater positioning accuracy, but also greater rigidity with compact dimensions. Thus exceeding in performance the application limits of the more traditional acme screw jacks.

Considering an advanced industrial context, where more and more frequently the need for high speeds and continuous operations, as well as load and positioning control, the designers evaluate with great interest solutions with higher performances, easier to control (position, load and speed), and able to guarantee a competitive advantage in terms of quality and quantity of the work performed.

A new concept in lifting systems

Based on this evolution, Servomech promotes a new concept in lifting systems, with an innovative approach, focused on the application of its high-performance ball screw jacks, with brushless motors and related drives and controls. Customers and designers are free to choose the brand of motors and drives they prefer.

Next generation lifting systems with Servomech high performance screw jacks, with ball screw, brushless motors and drives

The next generation of lifting systems proposed by Servomech allows to reach high linear speeds, high dynamic operations with relevant acceleration and deceleration, high positioning accuracy, exact position repeatability and operations with a continuous duty cycle. The synchronism between the various lifting points is carried out in the electrical axis, with the control in position or in both position and torque. The use of ball screw jacks equipped with servomotors, absolute multiturn encoders and drives capable of managing the motion capability of the motors and the control of the required current, allow for reaching high speed, precision and repeatability performance.

The traditional lifting systems are in low linear speed applications, with intermittent operating cycles, preferably with the use of acme screw jacks. Through different configurations depending on the needs and dimensions and through the mechanical connections with connecting shafts, mechanical couplings and motion transmission reducers, the screw jack with motor transmits the movement to the other lifting points through a mechanical synchronism. This solution has some limits, mostly related to linear and rotation speed, inertia masses involved and the lost power in the various transmission components, vibrations, noise and play that can be created between the mechanical connections, and the uncertain accuracy of the positioning of the various lifting points.

The new generation of lifting systems proposed by Servomech therefore broadens the application horizons of lifting systems in general with a modern and advanced approach. Lifting systems can now be used for continuous operations, for process functions, with also heavy load working cycles, with highly dynamic conditions, high speed, high accuracy and control.


Established in 1989, Servomech Spa always followed the entire production cycle internally within its factory in Anzola dell’Emilia, Bologna – ITALY. Specialized in the production of linear actuators, acme and ball screw drive, ball screw jacks, acme screw jacks, bevel gearboxes, ball screws and nuts.
