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.

The LEYG actuator is a rod type ball screw actuator paired with a bolt-on bearing block with double guide rods to resist rotational and lateral loads.  The LEYG motorless version permits the mounting of an AC servo motor other than the standard chosen by SMC.  Shaft coupling and mounting patterns are compatible with 8 servo motor series from 5 manufacturers.  Manufacturers include Mitsubishi, Yaskawa, Sanyo Denki, Omron, and Panasonic.
