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".
11-LEJS, High Rigidity Ball Screw Slider, Wide Body, AC Servo Motor, Clean Room
The 11-LEJS is the clean room version of SMC's LEJS ball screw slider. A built-in vacuum port is used to draw off particles generated by the ball screw and guide to achieve the ISO Class 4 standard. This model is fitted with an AC servo motor with incremental or absolute encoder. Optional drivers include pulse input and various communication protocols including Ethernet. Some option standard with LEJS are not offered with the 11-LEJS. Please consult the catalog for more information.
