Air Index Cylinder MDF Series

A rotary shaft type pneumatic indexing intermittent device that can be used as if it were an air cylinder.

Its internal cam structure ensures secure and accurate positioning.

This device's compact design also saves drive unit space.

Technical Information

Highlights

Index Like an Air Cylinder

Easy control via pneumatic control with solenoid valve.

One-way Endless Rotation

Indexing operation via cam meshing rotates endlessly in the same direction.

No Need to Specify Rotational Direction

Double-shaft type enables any direction of rotation.

Zero Cumulative Errors

No cumulative errors due to cam indexing.

No Shaft Return

Its rotating shaft has a built-in one-way clutch to prevent shaft return.

No Overruns

No overruns occur at the indexing completion position due to its reliable indexing stop structure.

Maintenance-free

Its grease-filled body does not require lubrication for its rated life.
