Dimensional drawings

• External: external actuator image and external dimension drawing available.
• Kaptive: kaptive actuator image and kaptive dimension drawing available.

Speed-thrust curves
Speed vs. thrust curves provided for different operating conditions and screw configurations to support selection and system integration.

Options

• Screw end machining: various end-machining and finishing options available to match mounting and coupling requirements.
• Teflon coating: for applications requiring greaseless screw–nut combinations, a Teflon-coated lead screw is available. Teflon coating extends service life and improves thrust generation compared with conventional SUS lead screws. Coating can be applied across all lead screw options and PM Stepper actuator types (External, Non-captive, Kaptive).
