ELS14 ~ Typical OEM Mounting
External Leadscrew Slides are an excellent alternative to conventional slides in tight-fit environments.  The key advantages are simplicity, space and cost savings.  ELS slides require no coupler nor near bearing system to support the screw. 

  • Integrated IP67 home sensor
  • Size 8, 11, 17, 23 and 34 actuator frame sizes
  • Open Loop Stepper w/ Speed and Position Mode Control
  • Closed Loop Servo w/ Speed, Position and Torque Mode Control
  • Anodized or Electro less Ni Housing and Tooling Plate
  • Light weight ceramic or precision ground stainless shafts
  • ELS lead options range from 0.635 mm/rev to 25.4 mm/rev.  Contact Nymotion for further information.
  • ELS Stepper Slides provide:
    • Micron and submicron positioning.
    • High Accuracy with Outstanding Repeatability
  • ELS Servo Slides provide:
    •
    • Micron and submicron positioning
    • Quicker, quieter motion profiles with no resonance
    • Dynamic position maintenence
    • Torque mode control.  "Move element A into B, maintain 10 lbs force for 30 seconds ..."
  • ELS Slides are based on External Linear Actuators, plane bearing carriages and precision ground 303 stainless shafting.  The target applications are high duty cycle (millions of strokes) maintenance-free automation applications.  Pick-and-place, dispensing, scanning and focus adjust.
    Greater repeatability.  +/- 1 to 5 microns (depending on lead and bearing selection.
    •
    • Programmable motion control.
    • Long stroke Z (lift) applications.
  • ELS assemblies have multiple threaded and c-bored mounting options with precision slip fit dowels.
  • Custom mounting plates with Z axis mounts and turn-key drive/controller kits are available on request.
