Description
11-LEJS, Electric Actuator, High Rigidity Slider, Ball Screw Drive, AC Servo Motor, Clean Room
The LEJS is the clean room version of SMC s high rigidity slider. The actuator has built-in vacuum piping with an exhaust port to achieve the ISO Class 4 standard. The 11-LEJS is 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.
