Linear motor
Material:
Coupling components are made of high-strength
aluminium. Spring elements are made of special
spring steel
Structure:
Input side: internal metric thread
Output side: external metric thread
The connection between the input and output
side of the coupling is via two sets of backlash
free leaf-spring systems.
