RACO-ELECTRIC CYLINDER MODULAR SYSTEM – HEAVY DUTY …

1 RACO-ELECTRIC CYLINDER . MODULAR SYSTEM HEAVY DUTY SERIES (TYPE 1). SIZE 4,5,6,7,8. HIGH-PERFORMANCE. ELECTRIC CYLINDERS: ROBUST, RELIABLE AND FLEXIBLE. RETRO-FITTING. The RACO actuator SYSTEM is of MODULAR design, and thus enables the combination of the most important integral elements of the electric CYLINDER such as the spindle-nut SYSTEM , the gearbox, the electric motor and the sensors. This versatility opens up a wide range of applications for the RACO electric CYLINDER type 1. components such as limit switches, Depending on the application in que- rotary impulse encoders, position stion, the suitable thrust-retraction transmitter, distance measurement unit of the electric CYLINDER can be systems and force measurement equipped with a DC motor, AC motor, systems.
