Couplings for TM series Torque Transducers

 
For our TM Torque Transducers, Magtrol offers MIC Series Couplings, BK2 Couplings, BK3 Couplings and BKC Couplings.
 
MIC Series Couplings Data Sheet
Features MIC Series Couplings
  • For use with Magtrol TM 301– 309 and TMB 303 – 309 In-Line Torque Transducers, as well as HD, WB and PB Dynamometers
  • Low inertia
  • Low weight
  • High rotational speed
Design
  • The couplings consist of one (MIC-6) or two (MIC-5) disc packs, two clamping hubs and a spacer.
  • They are both torsionally stiff and flexible in order to compensate for axial and angular misalignment when connecting two shaft ends
  • The MIC-5 double-element coupling also provides compensation for radial misalignment.
