Speed‑thrust curves
Speed‑thrust performance graphs are provided for the 36 mm PM actuator (typically two curve sets for different operating conditions) to assist selection.

Options

• Screw end machining: custom end machining options for lead screws available on request.
• Teflon coating: Teflon‑coated lead screws for greaseless screw‑nut combinations; coating can extend life and improve thrust versus conventional SUS lead screws. Available across lead screw options and all PM actuator types.
