FMR-70S-403, Torque: 4Nm, Weight: 830g, Damping direction: Both

Frequently bought together:


The FMR-70S-403 MRF damper by Bansbach uses magneto-rheological fluid which can go from a free moving liquid to semi-solid state in an instant. This gives you full control of damping torque with excellent response time.


  • Torque Electrically controlled by using MR fluid (magnetic-rheological fluid)
  • Eexcellent response due to fast electric operation
  • Flexible mounting in any direction
  • No pre-conditioning required.
  • Small differences between the static friction and dynamic friction allows for smooth actuation.
  • Sealing structure produces a long service life.
  • Seamless & stepless torque control.
  • Low susceptibility of temperature affect.
  • Low susceptibility of rotational speed affect.


  • Rated Torque: 4Nm
