Yes. PairGears provides a 6-month limited warranty for parts manufactured by PairGears. If a failure is confirmed to be caused by a manufacturing defect within the warranty period, we will arrange repair or replacement. What’s covered ...

Yes. We can provide practical guidance on common ISO and DIN standards used for gears—such as how an accuracy grade is specified on drawings and how it maps to inspection outputs. If you share your drawing note (ISO/DIN/AGMA grade), we’ll align the measurement/report package accordingly. ...

Yes. We can share a redacted sample inspection report to show the typical report format and scope (e.g., dimensional results, hardness, and gear profile/lead charts if required). Sensitive customer/project identifiers will be removed. What a “sample inspection report” usually cont...

Yes. For repeat orders, we can provide lot/batch traceability linking raw material (heat/batch) to key process records and final inspection for the shipped lot. The exact traceability depth depends on your program requirements and documentation package. What “traceability” typical...

Yes. We can provide FAI, COC (Certificate of Conformance), and material certificates as part of the shipment documentation when required. PPAP-related documents can also be supported for customer programs that require them. The exact document set is confirmed during quotation and onboarding. ...

Yes. We can provide tooth profile and lead charts and explain “pass/fail” by comparing measured deviations against the tolerance limits on your drawing (or the agreed standard/grade). “Pass” means the results stay within limits for the specified items. What “pass/fail” actually me...

Yes. If required, we can provide full gear measurement charts—including tooth profile, lead, and pitch—not just pass/fail. The report scope is confirmed during quotation (sample stage vs mass production, and which parameters are critical). What you’ll receive ...

Yes. We can produce gears and shafts based on physical samples. For best accuracy, sample-based projects usually require measurement + confirmation before cutting tooling, so the first-sample timeline may be longer than drawing-based projects. When sample-based production works be...

Yes. We can manufacture gears from your drawing or from a physical sample. A complete drawing is usually the fastest route; a sample is most useful when you want match-fit verification or the drawing is incomplete. When a drawing is enough ...

We can manufacture a custom precision gear from a complete drawing alone. A sample is helpful but not always required—it’s mainly used when drawings are incomplete, revisions are uncertain, or the mating-fit needs real-world verification. First-article inspection is commonly used to validate the first produced part against requirements before s...

Yes—a supplier can manufacture precision gears from a sample only, but it usually increases engineering/measurement work, which can raise cost and extend lead time, especially for tight tolerance or high accuracy grades. Reverse engineering typically requires accurate geometry capture and CAD definition before production. ...

Yes—we can measure third-party gears and provide inspection data as long as the part is legitimately obtained and the request doesn’t violate NDA/IP restrictions. Measurement scope depends on what you need (dimensions only vs full gear metrology) and what references you can provide (mating parts, application, drawings). Reverse engineering is o...

PairGears is a direct gear manufacturer (not a pure trading company). We run our own gear and shaft production operations—from machining and gear cutting to heat treatment and inspection—so we can control quality and delivery directly. What we manufacture in-house ...

For OEM repeat parts with existing tooling/fixtures, our typical production cycle is about 15 days. For custom gears requiring new tooling, samples usually take ~30 days, and mass production typically takes 15–30 days, depending on specifications and approval steps. ...
