This scotch yoke series covers torque values up to 850.000 Nm and it is been studied in detail to ensure high performance and long lasting quality.
Different sets of concentric springs have been designed to reduce dimensions; the spring pack can be separately assembled using screws which are easily accessible from the outside and without special tools.
With a basic and sturdy design, it takes up a minimal amount of space considering the torque it produces.
A wide range of variants will meet the different requirements of each plant and environmental use. Thanks to AFC expertise and flexibility, other solutions and certifications may be arranged and designed according to the customer specific needs.
As for every AFC actuators the part subjected to rubbing/friction are equipped with bearings and chromed surfaces.
