Speed Thrust Curves
Available Options
External Version
Supports applications where the nut translates along the lead screw and the screw remains fixed to the motor shaft.
Non-Captive Version
Supports compact linear motion designs where the screw travels through the motor and external guidance is provided.
Kaptive Version
Provides a guided short-stroke output configuration for simplified integration into compact mechanisms.
Teflon Coating
Teflon coated lead screw options are available when the application needs a greaseless screw and nut combination.
Customization Options
Screw End Machining
Customize screw ends to match coupling, mounting, retention, or driven load requirements.
Lead Screw Length
Adjust screw length to meet travel, packaging, and mechanical interface requirements.
Winding Review
Select 5V or 12V winding options based on voltage, current, speed, and available drive electronics.
Application Review
Work with DINGS’ Motion USA to review thrust, speed, duty cycle, stroke, lead code, and mounting needs.
