(Note) Contact CKD for chain drives and gear drives.
■ Operating conditions
1. Index 2. oscillator
Movement angleޓ Ψ (°) QTPQQHKPFGZGU
Moving time t1 (sec.)
Cycle time t0 (sec.) cycle time=moving time+dwelling time
(Note) Index time is movement time + settling time.
The settling time differs according to the working condition, but generally is between 0.05 and 0.2s.

Eccentric load caused by gravity from vertical
installation, external load caused by caulking work.
When using a spline, when unit cannot be fixed directly onto the device
(Fig.4), when there is a mechanism such as a chuck on the table.
When actuator is mounted on X-Y table or vertical
mechanism, etc., and mounted actuator moves.
