Hinged Steel Lamella 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.

Material Options For Hinged Steel Lamella Bellows

Our bellows are made exclusively from high-quality plastic fabrics and foils. We select the cover material and processing according to the design ambient conditions. Decisive factors are the mechanical and thermal strain of the bellows as well as the type of swarf and aggressiveness of the agents used. Exact details of the used materials may be gathered from the table of materials above.
