Steel Clad Bellows

Bellows Catalog » Download Quote Request »

Hennig has developed lamella bellows to meet particularly tough requirements.

This type fills the gap between telescopic steel covers and conventional bellows. The lamella bellows are based on our heat sealed or stitched designs. Each fold has its own guide frame which is secured to the cover material. Lamellas made from stainless steel protect the bellows against red hot, sharp-edged swarf, or mechanical strain.

FIXED STEEL CLAD BELLOWS

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.

HINGED STEEL CLAD BELLOWS

Vertically mounted bellows with no overhang. Hinged bellows are the perfect solution for protection of the Z-axis from hot / sharp chips, weld splatter, and any other debris from the machining environment. Each steel plate is flexibly attached to the PVC frame allowing the plates to lie flat on the bottom of the machine enclosure.
