Heat-Sealed Bellows

Heat-sealed bellows are a popular choice for covering machine ways and linear rails.  This style of bellows is applied in light to medium-duty environments, where small particles, light abrasives, occasional oil, chips or liquid are present.  For added protection, a heat-sealed bellows can be turned into a Gordillo way cover, accomplished by attaching protective stainless steel plates to the top of each convolution.

Features & Benefits:

  • No stitch holes, seams or breaks
  • Cover retains shape throughout travel
  • Stiffener profile can be made to match any way or rail geometry
  • Attractive, clean, uniform appearance
  • Excellent protection for linear bearings and other precision equipment

Design Info

Heat-sealed way covers are manufactured from a single sheet of thermoplastic-coated fabric which is pleated, and then thermic welded to a PVC stiffener at every fold. Heat-sealed bellows are free from stitch holes, seams or breaks. Heat-sealed bellows are available in any flat sided (non-circular) form, e.g. rectangular, flat/strip-type, or way cover. It can be fabricated with metal plates attached to each convolution for added protection against sparks and hot chips. See Gordillo construction for more information.
