AC Servo Sliders – High Rigidity Ball Screw

LEJS, Electric Actuator, High Rigidity Slider Type Ball Screw Drive (AC Servo Motor (100/200W)

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.

  • Body sizes: 40, 63
  • Maximum workload: 85 kg
  • Maximum speed: 1800 mm/s (H lead)
  • Maximum stroke: 1500 mm
  • Positioning repeatability: ±0.02mm
  • Motor available with either incremental 17-bit or absolute 18-bit encoder

25A-LEJS Electric Actuator, High Rigidity, Slider Type, Ball Screw Drive, AC Servo Motor, Secondary Battery

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.

  • Same features and performance as standard LEFS
  • Stainless steel bolts for construction
  • Low dew point grease functional down to -70°C
  • Copper and zinc free except for motor, cables, and controller
  • Non-standard materials for compatibility with secondary/rechargeable battery manufacturing
