Page 7: Function
Lateral loads and bending moments exerted on the round material damage its function and destroy the internal clamping component. • Load the round material only in the direction of movement. The use of a self-aligning rod coupler (è 3 Further information) prevents lateral forces. Festo — DNCKE-...-S / KEC-...-S — 2020-10e... -
