Aflex Bellows Assemblies
Aflex – Australia’s only paperless ISO9001:2015 accredited bellows manufacturer
Aflex (Formerly Axial Dynamics) manufactures a wide range of bellows assemblies or expansion joints, at our manufacturing facility in Sydney, NSW. All our bellows are manufactured in Australia, and we are proud to be Australia’s premier metal bellows manufacturer. We’ve listed some of our main assembly types below, however you may also want to check out our gallery page, updated daily, with our manufactured items.
