Linear Actuators

Hybrid Stepper

Haydon Kerk Motion Solutions offers a unique line of hybrid stepper motor linear actuators that open new avenues for equipment designers who require high performance and exceptional endurance in a very small package. These high-performance hybrid actuators directly drive a rotor drive nut on a stainless steel precision acme lead screw. This patented interface reduces tolerances and noise while increasing efficiency and durability over v-thread and bronze nut configuration commonly used in other linear actuators. Actuators are available in captive, non-captive and external linear configurations.
