  • Preload strategies for low backlash control
  • Consistent micro-machining quality for repeat supply

Typical Applications

  • Dexterous robotic finger actuation
  • Micro precision linear modules
  • Surgical and compact instrumentation mechanisms

Engineering Focus

  • Diameter and lead feasibility under load requirements
  • Backlash control and preload strategy for precision tasks
  • Fatigue and lifecycle behavior in repetitive micro-stroke use

Key Evaluation Matrix

MetricTypical RangeWhy It Matters
Diameter rangePhi 2.5-8 mmDetermines packaging feasibility in tight finger assemblies.
Lead range0.5-2 mm typicalControls speed-force balance in miniature drives.
Backlash strategyPreload nut options availableSupports 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.

RFQ Checklist

  1. Required diameter, lead, and stroke window
  2. Load profile and life-cycle target
  3. Backlash/preload requirement and precision class
  4. Sample quantity and consistency expectations

Risk Controls

  • Micro-scale tolerance drift across batches: Define lot-level dimensional and functional sampling criteria.
  • Early wear from under-defined load profile: Specify duty-cycle assumptions and life-test criteria during RFQ.
