Coupling joints

coupling joints

Double joints and coupling joints made of metal are heavy, often expensive and require extensive maintenance. The more economical alternative: igubal® series double joints and coupling joints.
They are made of polymers that bring about weight savings of up to 80% and cost savings of up to 40%. But not only that. The double joints and coupling joints made of plastic are easier to install and facilitate economic operations. They do not require any lubrication and are maintenance-free. 
The igubal® range of double joints and coupling joints is constantly growing. And thanks to a modular system with spherical balls made of various materials and housings of different shapes, you are sure to find your ideal solution.

Application examples for igubal coupling joints

igubal coupling joint in turbochargers

Turbocharger
Depending on the material, igubal coupling joints can be used at high temperatures and are therefore ideally suited for use in turbochargers. They are also characterised by their dirt-insensitive and corrosion-free use.

Double joint gearbox application

Gearbox
Metallic applications are replaced by igubal coupling joints in gearboxes, as the high-performance polymers reduce noise and dampen vibrations.

Controlled intake manifolds

Controlled intake manifolds
In contrast to coupling joints made of heavy metal, igubal polymer coupling joints show a low coefficient of wear and withstand frequent loads, in addition to the weight advantage.
