About LEKFS Electric Actuator

LEKFS combines a servo-driven ball screw with a rigid linear guide and enclosed slider body to produce controlled linear motion under offset and moment loads. Multiple frame sizes, screw leads and stroke lengths allow machine builders to balance thrust, travel speed and positioning resolution. The actuator can carry tooling, fixtures or workpieces directly on its table while maintaining alignment through repeated production cycles.

SMC supplies the series with compatible motors, controllers, cables and mounting accessories for integration into indexing, transfer, assembly and inspection equipment. Users select operating conditions through SMC sizing tools and configure position, speed and acceleration in the associated controller. The product is sold as a configurable industrial motion component through SMC’s global automation distribution and engineering network.
