Low Backlash & High Precision Actuator

Ultra-precise linear motion for testing, dispensing, and micro-positioning, featuring preloaded roller screws for zero-backlash reversal.

Target Buyer:Test Engineers and Precision Machine Builders requiring exact bi-directional repeatability.
Low backlash high precision roller screw actuator

Best Fit

  • Aerospace test stands
  • Fluid dispensing systems
  • Optical and laser positioning

Review Before Sizing

  • Precision thread grinding
  • Bearing preload calibration
  • Thermal expansion compensation

Capability Highlights

  • Preloaded split-nut designs for zero axial play
  • ISO Class 3 lead accuracy options
  • Rigorous CMM verification for every assembly

Typical Applications

  • Aerospace test stands
  • Fluid dispensing systems
  • Optical and laser positioning

Engineering Focus

  • Precision thread grinding
  • Bearing preload calibration
  • Thermal expansion compensation

Key Evaluation Matrix

MetricTypical RangeWhy It Matters
Backlash< 0.01 mm to ZeroCritical for precision dispensing and accurate force-curve testing upon motion reversal.
Repeatability±0.005 mm to ±0.01 mmEnsures identical positioning across thousands of cycles.

RFQ Checklist

  1. Acceptable backlash limit
  2. Bi-directional repeatability requirement
  3. Operating temperature range (for thermal expansion)

Risk Controls

  • Loss of preload over time: Use of high-hardness planetary rollers and calibrated split-nut preloading during assembly.

Factory Validation Evidence

  • Use of high-hardness planetary rollers and calibrated split-nut preloading during assembly.

Buying Notes

  • Acceptable backlash limit
  • Bi-directional repeatability requirement
  • Operating temperature range (for thermal expansion)

Buyer FAQ

Can you guarantee zero backlash?

Yes, through a preloaded nut design. Note that this requires slightly higher running torque and careful thermal management.
