Torsion bars for industry

A torsion bar is an active component used to supplement or in some cases replace coil springs used in suspension units.

The workmanship with the different spring steels used and the precision machining allow us to offer a great variety of types of torsion bars :

  • Straight bars
  • Bent bars
  • With or Without levers ( mounting with splinning or hot crimping).

Another application of torsion bars is the transmission of torque with limited distortion.
