Key Evaluation Matrix
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Diameter range | Phi 2.5-8 mm | Determines packaging feasibility in tight finger assemblies. |
| Lead range | 0.5-2 mm typical | Controls speed-force balance in miniature drives. |
| Backlash strategy | Preload nut options available | Supports repeatable micro-positioning and haptic control. |
Compliance and Trade Guidance
CE, RoHS, and REACH documentation support is available by project scope. HS classification should be treated as reference guidance only and must be confirmed by importer/broker based on destination rules and final product configuration.
- Confirm required compliance document list before sample planning.
- Include destination market and declaration scope in your RFQ message.
- Review detailed guidance in Resources / Compliance.

Buyer FAQ
Can you support engineering samples before high-volume release?
Yes. We support sample builds and validation planning before mass-production commitment.
Can you provide drawing and model files for integration?
Yes. STEP/IGES support is available after requirement alignment.
