Product Description
MIC Miniature Couplings provide the ideal complement to Magtrol’s TM / TMB / TMHS / TS In-Line Torque Transducers, when they are mounted in a drive train. They can also be used with any Magtrol Hysteresis (HD), Eddy-Current (WB) or Powder Brake (PB) Dynamometer and Hysteresis Brake (HB).
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.
On demand, MIC Series Couplings are available in an electrically isolated version, suitable for temperature up to 100 °C (125 °C max. temperature, short term).

a) The specified maximum speed may require specific balancing. By default, Magtrol delivers couplings without balancing.
b) Axial and angular misalignments and torsional spring rate refer to single-element coupling (MIC-6-xxxx).
c) Radial misalignments refer to double element coupling (MIC-5-xxxx).
d) At maximum bore
e) Value available on request.
f) The standard versions are manufactured with integer values; the standard tolerance is H7. All diameters and tolerances are possible. Please contact our sales department.
g) CAUTION: for small diameters, the torque can be reduced < 40 %. For more information, please contact our sales department.
Applications
In a drive train installation, double-element miniature couplings are the ideal complement, although single-element couplings can be used for low speed applications in a suspended installation of the toque sensor.
The higher the speed of the application, the more care is required in selecting the coupling and assembling (alignment and balancing) the drive train configuration. Your Magtrol sales representative can assist you in choosing the right coupling for your transducer.
Coupling Selection
In order to ensure a sufficient safety margin, Magtrol recommends that couplings be sized according to the maximum torque supported by the torque transducer. It is strongly recommended to protect all rotating machine parts according to Safety Machine Norms for avoiding injuries. For further information, please contact our sales network who will be able to provide you with personal advice.
