These bellows are essential for the longevity of CNC equipment. They expand and compress along the axis of travel. The internal stiffeners ensure the bellow maintains its square shape and does not collapse onto the rail. The outer fabric is resistant to abrasion and chemical coolants.

Often used to cover the opening below the spindle on large milling machines, this cover hangs like a flexible steel wall. It can roll up into a canister at the top or fold away. The metal links are strong enough to deflect heavy, hot chips that would melt fabric covers.
