Ball Screw Drive

An LEFS slider, or rodless, type electric actuator features a load mounting platform situated above a ball screw drive. A flexible seal band permits platform movement while preventing grease and foreign matter from entering the drive. Advantages include a low profile height, shorter overall length than rod types, and better positioning repeatability than belt drives.

11-LEFS, Electric Actuator, Slider Type, Ball-L-bP

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 50mm increments only.

LEFS Electric Actuator, Slider Type, Ball Scr-L-eM

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.

25A-LEFS Electric Actuator, Slider Type, Ball-L-d7

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.
