Product Key Facts
Product Description
High speed and low speed backstop with sprag lift off and roller ramps design. Available either with or without radial support bearings and a reaction torque arm.

High speed shafts and low speed shafts of machinery driven by electric motors and requiring freewheeling, indexing or backstop functions.


  • High material stiffness, low material density
  • Excellent fatigue strength
  • Intrinsic low unbalance

Tailor-made solutions

  • Adaptable bending and torsional stiffness of the shaft
  • System solution integration: composite shafting with integrated torsional flexible couplings
  • Reliable electrical isolation of the drive train


  • Complete engineering and project development
  • Combination with flexible couplings is available
  • In-house testing 1:1 up to 5.000 kNm nominal torque
