TOOLFLEX® metal bellow-type couplings

The TOOLFLEX is a metal bellows coupling that is backlash-free, torsionally stiff and flexible – as an all-metal coupling with a stainless steel bellows. Depending on the size and type, aluminium or steel is used as the material for the coupling hubs - in each case to match the selected type of shaft connection.

The metal bellow optimally compensates for axial, radial and angular displacements with conformal torque transmission and low restoring forces.

At the same time TOOLFLEX has a high torsional stiffness and a low mass moment of inertia. It is free from wear and maintenance and extremely easy to assemble.

Applications of our TOOLFLEX metal bellow-type coupling®

The TOOLFLEX metal bellow-type couplings are used wherever accurate positioning and backlash-free torque transmission are required.

Typical applications are as follows:

  • Servo gearboxes
  • Highly dynamic axes of packaging machines and machine tools
  • Automation technology
  • Medical technology
  • Packaging machinery
  • Machine tools

Various hub types, such as clamping hubs, as well as two bellows lengths are available for the different applications and mounting situations of the TOOLFLEX: Type S with 4 layers and type M with 6 layers.

Technical benefits

As a precision coupling, TOOLFLEX® combines maximum accuracy with
flexibility and durability. It is ideal for dynamic applications and connections with narrow installation spaces.
