Fixed Steel Lamella Bellows for CNC Machine Tools
Fixed bellows fill the gap between telescopic steel covers and conventional bellows. Stainless Steel cladding protects the bellows against red-hot debris, sharp-edged swarf, or mechanical strain. Each fold has its own guide frame which is attached to the cover material.
