Mechanisms

Mainly based on the APA concept, the CEDRAT Group has developed different mechanisms in order to fulfill its customers' requests for several degrees of freedom kinematics. These mechanisms take advantages of the APA concept offering a reliable, robust, precise and compact solution to the users.
These Standard mechanisms are currently available in order to meet various needs in terms of kinematics and force:
