The LEF series slider type electric actuator features a low profile height of 46mm *. The actuators 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

The rodless LEFS slider is an electric actuator with a load mounting platform situated above a ball screw drive.  A flexible seal band permits platform travel while preventing foreign matter from entering the drive.  Slider advantages include a low profile height, shorter length than a rod with equivalent stroke, and better positioning repeatability than a belt driven slider.  This version
