LEJS, Electric Actuator, High Rigidity Ball Screw Slider, Wide Body, AC Servo Motor

The LEJS is a slider type electric actuator available exclusively with an AC servo motor. The actuator features a substantially wider load mounting platform than the LEFS, supported internally by a double axis linear guide for reduced moment deflection. The AC servo motor enables higher speed and acceleration, as well as a high-load size 63 model exclusive to LEJ. The drivers are pulse input type, with both incremental and absolute encoder options and 17- or 18-bit resolution.
