How to Use the Damper

  1. The damper generates torque in both the clockwise and counter-clockwise directions. (A one-way clutch is built in inside the damper.)
  2. Please make sure that the shaft attached to a damper has a bearing, as the damper itself is not fitted with one.
  3. It can be used as a free-stop for a load that is smaller than the rated torque.
    4. fig
  4. Please refer to the recommended dimensions below when creating a shaft for attachment to the damper. Using a shaft outside of the recommended dimensions may cause the shaft to slip out.
  5. To insert a shaft into the damper, insert the shaft while spinning it in the opposite direction of the damperʼs direction of torque generation. (Do not force the shaft in from a regular direction. This may damage the built-in oneway clutch.)
