COATED FABRIC BELLOWS AND WAY COVERS
Industrial coated fabric bellows are great for dust protection, laser machines, and guideways that don't see high chip loads. They offer maximum compression and flexibility in a wide range of materials for a wide range of environments. Our bellows can be made folded to cover multiple sides, flat to cover a single side, or round for protecting shafts and other cylindrical machine components.

MATERIAL OPTIONS FOR COATED FABRIC 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.
