Coated Fabric Bellows

Maximum compression and flexibility in a wide range of materials for a wide range of environments. Industrial coated fabric bellows are great for dust protection, laser machines, and guideways that donʼt see a lot of chip loads.

Coated fabric bellows can be assembled using the heat-selaed, glued, or the stitched method. Our bellows can be made as a folded bellow to cover multiple sides, as a flat bellow to cover a single side, or round bellow for protecting shafts and other cylindrical machine components.
