Rotary actuators

The FH series AC servo actuators' flat shape and hollow-shaft construction makes possible downsizing of machinery/equipment and structural simplification.

Product's features:
•Thin and compact configuration;
• Hollow-shaft construction;
• High torque, high rigidity, high accuracy;
• Built-in high-rigidity support mechanism;
• Availability of a series of multifunctional control units.
Used for:
•Machine tools:Tool revolvers, index tables, loaders;
•Industrial robots: for whirling and articulated drives;
•Semiconductor manufacturing equipment: for transport robots,
inspection tables;
•Liquid crystal manufacturing equipment: for transport robots,
inspection tables, sensitizer application roll driving mechanisms;
•Printing machines: for sensitizer application roll driving sections.
