Electric actuators that realize linear motion for industrial robots and automation equipment. They provide high-precision positioning and stable linear operation through ball screw, belt, and rack & pinion drive systems. These are essential drive components for manufacturing line automation, including workpiece transport, press processing, assembly operations, positioning in inspection equipment, and lifting operations in palletizers. Wide lineup available from stepping motor and servo motor built-in types to high-precision specifications with encoders. Clearly distinguished from rotary motors, classified as electric drive devices dedicated to linear motion.
