AC Servo Sliders - High Rigidity Ball Screw
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.
LEJS, Electric Actuator, High Rigidity Slider Type Ball Screw Drive (AC Servo Motor (100/200W)
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.
LEJS, Electric Actuator, High Rigidity Slider Type, Ball Screw Drive, Motorless
The LEJS is available in a motorless type, permitting 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.
11-LEJS, Electric Actuator, High Rigidity Slider Type 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.
25A-LEJS Electric Actuator, High Rigidity, Slider Type, Ball Screw Drive, AC Servo Motor, Secondary Battery
The 25A- series variations are compatible with secondary battery manufacturing for electronics, automotive, and other vehicle types. Design goals include eliminating copper (Cu) and zinc (Zn) materials where possible, and employing a low dew point grease that retains lubricity even in low manufacturing termpertures. Please note the copper and zinc materials are used for the motors, cables, controllers and drivers.
