Assembly with screw reducer and rear clevis mounting

Actuators with this assembly are the most economical, reliable and efficient solution in many applications where performance requirements are not the most stringent. The screw gearbox design allows the motor to be mounted perpendicularly, reducing the mounting centre distance.

Depending on your requirements, they are available in MST (trapezoidal screw) or MSK (ball screw) versions.

Depending on the application, electric actuators can be fitted with 400 V-3 AC three-phase asynchronous motors, electronically commutated EC brushless servomotors or 24-48 V DC direct current motors.

Numerous options are also available for these actuators: 2 limit switches, absolute or incremental encoder for precise servo-control and multiple position control, mechanical mounting brackets....

These actuators cover a range of displacement forces from 100 daN to 200,000 daN for speeds from 5 to 100 mm/sec and strokes from 100mm to 10,000mm.

Application example: Electric actuator for opening and closing a door in a flood protection system for a nuclear power plant.
