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 provide a landed cost estimate under FOB/CIF/DDP and recommend typical shipping options once we know your destination and basic shipment details (weight/volume, sample vs bulk). What we can quote FOB:...

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 ...

Our gear products have the characteristics of high precision, high durability and high performance.All our products have ready-made molds and tools, which can be produced and delivered quickly.At the same time, we provide customized services and carry out personalized , design and manufacturing according to the specific needs of customers. ...

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. ...

If you have the actual product, you can express it directly to us.

PairGears attaches great importance to the security and confidentiality of customer information. We sign confidentiality agreements with each customer to clarify confidentiality responsibilities and obligations. Samples, drawings, or other technical documents provided by customers will be kept strictly confidential...

PairGears supports fast sample delivery via major international couriers (e.g., FedEx, DHL, UPS) and bulk shipment via ocean freight with booking support and export customs coordination. Delivery method and timing depend on destination, Incoterms, shipment size/weight, and any customs documentation needs. ...

PairGears offers a range of services tailored to gear-related projects:Product Technical Consultation: Expert advice on gear specifications and requirements.Product Design: Customized design solutions to meet your needs.Quoting: Transparent and competitive pricing for your projects.Prototyping: High-quality prototypes for testing and evalua...

PairGears’ typical monthly production capacity is up to 1,000,000 gear and shaft pieces. Actual deliverable output depends on part mix, process route, bottleneck operations, and inspection scope, so we confirm capacity after reviewing your specs and schedule. What “production capa...

Yes. PairGears provides a 6-month limited warranty for parts manufactured by PairGears. During the warranty period, if a failure is caused by a manufacturing defect, we will arrange repair or replacement at no charge (subject to claim review). Limited warranties commonly cover defects in materials/workmanship and exclude misuse or improper hand...

We accept T/T (Telegraphic Transfer / bank wire). Our standard payment term is 30% deposit after order confirmation, with the remaining 70% balance paid before shipment. T/T is a common method for international bank-to-bank transfers. What “T/T” means ...

To quote and manufacture custom gears/shafts accurately, please provide either a sample or a detailed drawing, plus the key specs: gear geometry (module/DP, teeth, pressure angle, helix), material & heat treatment, accuracy/inspection needs, and your quantity/lead-time target. If you’re unsure about any parameter, tell us the application and ma...

Yes, we can customize gears and shafts of various sizes, specifications, and materials according to your requirements. Whether you need small gears or large shafts, we can provide customized solutions to meet your specific needs. Additionally, we can offer customized package for our customers, include the color box...

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. What this lead...

For customized gears, the first sample lead time is typically 15–30 days. After sample confirmation, the lead time for bulk orders is usually within 30–45 days. Lead time is commonly understood as the time from order initiation/confirmation through production and shipment readiness (and it can vary by process route and release steps). ...

For newly developed custom parts, PairGears has no minimum order quantity (MOQ)—we can develop and produce even 1 piece. However, for new custom products, customers are required to cover the tooling cost (tools/fixtures/cutters/gauges needed to develop and manufacture the part). MOQ commonly means the smallest quantity a supplier will accept pe...
