RTI Electric Actuators

Reliable and accurate linear movement!

The electric actuator is a component used in several industrial applications, and , due to the energy saving, often replaces the use of pneumatic and hydraulic actuators . Today many process controls, from automotive to food, from packaging to the industry of the sheets processing,  are solved  with RTI electric actuators.
Today, the actuators range  is very wide and includes solution involving recirculating ball screw and trapezoidal screw from diameter  12 to 63mm and  strokes up to 1000mm.  The product can be supplied in standard execution or on special  design, according customer specifications.
The experience reached during these years has enabled us to select valid partner for the supply of control electrical components : all actuators can be supplied without motors or complete with control systems.
The whole design, production and assembly are carried out in our Turin plant, ensuring quality, accuracy and reliability, which are the main features of made in Italy products.
