Ball Screw Drive
11-LEFS, Electric Actuator, Slider Type, Ball-L-VL
The 11-LEFS is the clean room version of the standard LEFS. This version is only available with the inline motor. Strokes are available in 100mm increments only.
LEFS Electric Actuator, Slider Type, Ball Scr-L-TO
The original LEFS slider features an inline motor with a cover. Because the motor drives the ballscrew directly, additional cost of a belt and pulley system is avoided. The motor cover is taller than the load platform, so be aware of potential interference at the origin position.
LEFS, Electric Actuator, Slider Type, Paralle-L-Nx
The LEFS with parallel motor mounts, mounts the motor alongside the actuator axis. The motor is coupled to the ballscrew by a belt and pulley system. This model has two advantages. The overall length is considerably shorter than the inline LEFS, and the motor is below the surface height of the load platform to avoid interference. Motors can be mounted to the left or right of the axis.
LEFS, Electric Actuator, Slider Type, Ball Sc-L-ze
The LEFS 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 Kenki, Omron, and Panasonic.
25A-LEFS Electric Actuator, Slider Type, Ball-L-Pj
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 temperatures. Please note that copper and zinc materials are used for the motors, cables, controllers and drivers.
