Speed Thrust Curves
Speed-thrust curves are provided for Single Stack and Double Stack motor configurations. Test condition: Testing Voltage 24Vdc, Driver Model DS-OLS2-FPD bipolar, chopper driver at rated current (rms). Motor thrust will change with different voltage and driver. 50% thrust margin is recommended.

Options

• Screw End Machining (optional)
• Teflon Coating: Teflon coated lead screw available for greaseless screw/nut combination; increases lifecycle and improves thrust vs conventional SUS lead screw. Can be applied across all lead screw options and actuator types. Anti-backlash nut can be combined with Teflon coating.
• External Anti-Backlash Nut: length may change according to screw lead code selection.
• Non-Captive Anti-Backlash Nut.
• Encoder Option: EK1 and EK2 encoder options with multiple resolutions and output types.
