RFQ Checklist

  1. Joint axis function and motion profile
  2. Backlash and stiffness acceptance threshold
  3. Load spectrum and safety factor target
  4. Expected lifecycle and maintenance assumptions
  5. Sample validation method and evidence format

Risk Controls

  • Precision drift under long-cycle operation: Define incoming and outgoing backlash/stiffness verification with trend tracking.
  • Early wear from unexpected impact profile: Align actual shock spectrum and include margin in reducer selection.
  • Assembly-induced runout affecting control quality: Use fixture/process controls and CMM-based verification for key interfaces.

Buyer FAQ

Can you support custom interface dimensions on this module?

Yes. Interface adaptation is supported with DFM and tolerance-risk assessment.

How should we define acceptance criteria for pilot lots?

Use measurable thresholds for backlash, stiffness, and repeatability under your representative load profile.

Do you support lifecycle and reliability discussions pre-PO?

Yes. Share lifecycle targets and application duty so we can align recommendation and validation scope.
