Dimensional drawings
Dimensional drawings and reference images are provided for External and Kaptive types to support installation planning. Note: available stroke for the 15 mm Kaptive type is 13 mm.

Speed-thrust curves
Speed vs. thrust performance curves are available for the 15 mm PM actuator and can be supplied on request for system design.

Options

• Screw end machining: custom end machining for mounting or coupling requirements
• Teflon coating: DINGS offers Teflon-coated lead screws for grease-free applications. Teflon coating extends life cycle and can improve thrust generation compared with conventional SUS lead screws. Coating is available across all lead screw options and PM actuator types (External, Non-Captive, Kaptive).
