Fabric expansion bellows are an extremely flexible and cost-effective solution for low quantity applications.

There are many applications in industry which benefit greatly from the need to use KMK fabric expansion bellows:

  • Conducting air and other gases
  • Protecting screws and rams
  • Vibration and noise elimination in ducting
  • Accommodating axial and lateral movement

KMK fabric expansion bellows are manufactured from a choice of specially woven fabrics that have been impregnated with selected elastomers to promote strength and resilience.

We have three basic types of fabric bellows;

  • formed
  • sewn
  • shaped

In three distinct profiles.

Profile 1

Profile 2

Profile 3

Formed Fabric Bellows

This type of bellows is produced using metal forming tools which results in a seamless, gas tight bellows ideal for conducting air or other gases.

Sewn Fabric Bellows

Where there are requirements for very small inside dimensions or large convolutions then sewing is the ideal manufacturing method.

Shaped Fabric Bellows

For very large bellows, where forming or sewing are not practicable, these can be shaped by hand using an appropriate wire reinforced material.

Design Features

Each type can incorporate additional design features:

  • Extension Control Tapes
  • Pressure Support Rings
  • Breather Vents
  • Centralising Discs

Split Bellows can be produced when an application cannot be dismantled, to wrap around and be fixed by means of a zip, Velcro or press studs.
