Sewn Folded Bellows

Sewn folded bellows are made from a single sheet of thermoplastic-coated or elastomer-coated fabric, sewn to a PVC stiffener at each fold. They are available in any flat-sided form, and the stiffener profile can be fabricated to match virtually any guideway geometry.

For applications involving heavier coolant exposure, heat-sealed construction is recommended, as the stitching design offers less water resistance.

For enhanced protection against sparks and chips, lamellas (stainless steel shields) can be added to the top of each convolution, converting a sewn folded bellows into a lamella-style bellows.
