Hinged Steel Lamella Bellows

Hinged Steel Belt Bellow Cover Render

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.
