The IT series intermittent drives and the OT series oscillating drives are mechanical square axis devices. A mechanical barrel cam and followers transform the inlet shaft uniform rotation into intermittent rotation (as regards IT series), or an intermittent oscillation (as regards OT series), at the outlet. Also for the IT series, the number of standard indexing can range from 2 up to 32; over 32, up to 540 on request (it is also available the continuous type). Standard oscillating angle of the OT series can be up to 90°. As a rule for all the production, Autorotor applies the most suitable motion law for specific customer's need, following exact mathematical functions.
