No certification is claimed on this page. Quality requirements should be defined in the RFQ and purchase documents.
Use revision-controlled drawings with tooth data, datums, tolerances, heat-treatment zones and critical-to-function dimensions.
Specify material verification, hardness, runout, pitch/lead measurements, dimensional reports and contact-pattern checks as required.
Prototype or first-article approval should identify the accepted revision and any deviations.
State the required level of batch, material, heat-treatment and inspection traceability before quotation.
