LEYG, Electric Actuator, Guide Rod, Motorless
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.
