AC Servo Rod
Similar to the Rod and Guided Rod type except utilizes an AC servo motor instead of a DC type. The AC servo motor enables higher speed and acceleration, as well as improved vertical load capability. The drivers are pulse input type, with both incremental and absolute encoder options and 17- or 18-bit resolution.
Rod Type with AC Servo
The AC servo version of the LEY rod features an AC servo motor instead of a DC version. The AC servo motor enables higher speed, acceleration, and pushing force, as well as a size 63 model not available in a DC version. The drivers are pulse input type, with both incremental and absolute encoder options and 17- or 18-bit resolution.
Rod, IP65 IP69K Protection Class
The X5 option, available for the LEY series in sizes 25 and 32, is a dust and drip proof specification equivalent to IP65. The AC servo motors do not require enclosures, but the scraper and lube-retainer configurations are included. Additionally, the body extrusion includes a vent hole and fitting to balance internal pressure so that dust and water are not drawn in.
AC Servo Guided Rod
The AC servo version of the LEYG guided rod features an AC servo motor instead of a DC version. The actuator features a bolt-on bearing block with double guide rods that resist rotational and lateral loads. The AC servo motor enables higher speed, acceleration, and pushing force. The drivers are pulse input type, with both incremental and absolute encoder options and 17- or 18-bit resolution.Industry Applications
In the packaging industry, these electric actuators are primarily used for high-speed sorting, case packing, and precision labeling where synchronized movement is critical. The LEYG guided rod series is particularly effective for pick and place operations, as its integrated guides handle the lateral forces of rapid horizontal movement, while the standard LEY series provides the high acceleration needed to maintain fast cycle times on conveyor lines.
In the CNC machining sector, the dust and drip-proof IP65 rated models are essential for automated tool changing and workpiece positioning within the splash zone of the machine. Their robust sealing protects the internal lead screw and motor from metal shavings and coolant spray, ensuring long-term reliability in harsh machining environments where pneumatic or standard electric cylinders might fail due to contamination.
