Fabric Expansion Bellows

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

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

Fabric bellows: Profile 1

Profile 2

Fabric bellows: Profile 2

Profile 3

Fabric bellows: 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.

Metallic Bellows, Moulded Rubber Bellows and Hose Assemblies

We offer supplies of a full range of Metallic Bellows (round or rectangular) from simple exhaust and axial units to complex double Gimbals and Hinged applications.

Moulded Rubber Bellows from metal flanged, tied or untied to full Hand Built Rubber Bellows: and Hose Assemblies with elastomer liners up to 16 bar g or with stainless steel liners and overbraid for higher pressures and chemical resistance.
