Linear Actuator Direct Drive
Harmonic Drive designs and manufactures high-precision linear actuators for various applications. We have over 60 years of experience innovating components for the precision motion control market. Our committed development and engineering teams build linear servo actuators that can help your OEM equipment deliver optimal performance.
Linear Actuators Back to top
Servo actuators are assemblies of a zero-backlash gear, an AC or DC servo motor and a high-capacity output bearing. Our high-force components deliver linear forces from 49N to 12,000N with sub-micron position resolution.
Here are the linear actuators we provide:
LAH Linear Actuator
The LAH series comprises LAH-46 for DC motor drives and LAH-80 for stepper motors. If you prefer, you can change LAH-46's DC motor to a stepper option. The two models have a precision ball screw that provides 1 micron or less repeatability and a positioning accuracy of 4 microns. Their force ranges from 392N to 3,000N.
This high repeatability and position accuracy make them ideal for critical applications such as manufacturing measuring instruments, test and inspection systems, optical equipment, semiconductors and LCDs.
The LAH series supports a flange mount type.
LA Servo Linear Actuator
The LA Series is a compact linear actuator with high resolution and high thrust. It is available in two models: LA-30B-10F and LA-32-30-F. The series has a maximum thrust of force 49N, 0.0174 micrometers of resolution and high precision.
Like the LAH series, the LA models feature a precision ball screw, support a flange mount type and are suitable for similar use cases due to their two-micron position accuracy and 0.1-micron repeatability.
LBC Linear Servo Actuator
LBC linear actuators are available in two models: LBC-25A-5D6K, with a maximum thrust force of 6000N and 0.32 micrometers of resolution, and LBC-25A-5D12K, with a maximum thrust force of 12000N and 0.16 micrometers of resolution.
The LBC models use AC servo motors and precise trapezoidal screws and support a base-mount installation. They are compact and provide smooth motion at high and low speeds. You can use them to build automation equipment for medical packaging, electronics assembly and other high-precision use cases.
