Speed‑thrust curves
Speed‑thrust characteristic graphs are provided to assist selection and performance evaluation. Two condition-specific graphs are typically available for the 36 mm PM actuator.

Options

• Screw end machining: Custom screw-end machining is available on request.
• Teflon coating: Teflon-coated lead screws are offered for greaseless screw-and-nut combinations. Teflon coating extends service life and can improve thrust generation compared with standard SUS lead screws. Coating is available across the DINGS lead screw range and for all PM actuator types (External, Non-Captive, Kaptive).
