Haydon Kerk Pittman Hybrid Stepper Linear Actuators (16000–87000 Series)
Vendor: Haydon Kerk Pittman / AMETEK (USA)
Product: Hybrid Stepper Linear Actuator (16000–87000 )

Haydon Kerk Pittman (AMETEK) hybrid stepper linear actuators convert hybrid stepper rotation into linear motion via a stainless-steel precision modified ACME lead screw / direct-drive rotor nut, in Captive, Non-Captive and External configurations. Range spans Size 6–Size 34 (16–87 mm frame), 1.5–127 µm travel per step, 2–2224 N max force, 12.7–63.5 mm captive stroke and up to 400–500 mm non-captive/external stroke, for medical, semiconductor and lab-automation precision positioning.
