These are linear actuators that combine precision Harmonic Drive™ gearing with precision-engineered lead screws. These linear actuators are designed for applications which require micron-level precision, such as inspection/measuring/optical instruments, semiconductor and liquid crystal board manufacturing equipment, etc., as well as for 12,000 Newton-level high-thrust positioning work. Ultra precision positioning actuators: LA series LNP series High speed positioning actuators: LACH series Medium thrust actuators: LAH series High thrust actuators: LBC series
