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

The LEFS slider features a load mounting platform 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 and shorter length than a rod with equivalent stroke.  The optional parallel mounted motor places the motor alongside the platform axis.  This arrangement
