Capability Highlights

  • Machining and inspection language for serious gearbox procurement
  • CTQ review for housing, shaft, bearing, and gear interfaces
  • Documentation expectations for repeatable export supply

Typical Engagement Scope

  • Precision gearbox sourcing qualification
  • OEM supplier audits
  • Custom gearbox manufacturing programs
  • Private-label reducer projects

Execution Focus

  • Critical tolerances on bearing seats, shafts, gears, and housings
  • Gear measurement, backlash inspection, and assembly records
  • Material, heat treatment, surface finish, and lubrication control
  • Outgoing inspection and traceable lot documentation

RFQ Preparation Checklist

  1. Define CTQ dimensions and required inspection records
  2. Share material, hardness, heat treatment, and finish expectations
  3. State sample inspection report and batch documentation needs
  4. Confirm packaging protection for machined and assembled gearboxes

Risk and Mitigation

  • Quality expectations stay implicit: List required documents, CTQ dimensions, and inspection method before quotation.
  • Assembly performance varies by lot: Use revision control, incoming checks, assembly procedure, and outgoing test records.

Buyer FAQ

Can you support inspection records for gearbox projects?

Inspection scope can be aligned by project. Buyers should list required report types at RFQ stage.

Why does machining control matter for reducers?

Small errors in bearing seats, gear geometry, shaft alignment, and assembly stack-up can cause noise, heat, backlash, and early wear.
