LEKFS, High Rigidity Slider, Ball Screw Drive, Motorless

The rodless LEKFS 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.  LEKFS includes a redesigned guide with 4 rows of steel balls instead of 2, improving both allowable moment rigidity and positioning repeatability.  Additional enhancements vs. the LEFS include auto switch mounting grooves, improved dustproof perfomance with magnetic seal band adhesion, standard positioning pin holes and drop-in upgrade replacement vs. LEFS.  The motorless version permits the mounting of an AC servo motor other than the standard chosen by SMC.  Shaft coupling and mounting patterns are compatible with servo motors from at least 18 different manufacturers.  Manufacturers include FANUC, Rockwell Automation, Siements, Beckhoff, Mitsubishi, YASKAWA, OMRON, Panasonic and others.
