Fabric
Typical applications include the protection of screw down gear on rolling mills and hydraulic rams on heavy presses, plus the fabrication of cooling air ducts on traction motors for diesel-electric locomotives. They are also popular as slide covers.
Based on heavy duty elastomer proofed fabrics, these bellows are of totally vulcanised construction that provides a particularly rugged product.
Various layers are preformed prior to the vulcanising process: this avoids the weakness inherent in bellows fabricated from seperate pieces joined by stitching or other mechanical means.
