Clean Room Products - AC Servo Sliders
The LEF series slider type electric actuator features a low profile height of 46mm (LEF16). The actuator's main body can be mounted without removing any exterior components, such as the cover, making installation easy. The standard equipped seal band covers the guide, ball screw and belt, preventing grease and external foreign matter from splashing and entering the LEF. There are 2 types of drivers available, ball screw or timing belt. Available motors include servo motor ball screw drive or step motor belt drive. When the LEF is ordered with the controller, initial data of the actuator is preset in the controller allowing start-up in a short time with the "easy mode".

- Same features and performance as standard LEFS AC Servo, plus:
- ISO Class 4 / US FED STD 209E Class 10
- Built-in vacuum piping with exhaust port for removing generated particles
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.
