6mm Bore 20mmOD 25mmL Screw Coupling


Out of stock

Product Details:

  • Aluminum alloy as raw material: torsionally stiff with dampening and lightweight for low intertia
  • Since it is a single piece metallic flexible coupling, there does not exhibit the backlash
  • Multiple beam cuts improve parallel misalignment capabilities
  • The flexing action compensates parallel, angular misalignment and shaft end-play
  • Constant velocity and accommodate axial motion

One-piece metallic flexible coupling for step motor connect, servo applications and also the most common applications are attaching encoders to shafts and motion control for robotics.

  • Performance ratings are for guidance only. The user must determine suitability for a particular application.
  • Also, torque ratings for the couplings are based on the physical limitations/failure point of the machined beams.
  • Under normal/typical conditions the hubs are capable of holding up to the rated torque of the machined beams.
  • In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the rated torque of the machined beams.
