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.
