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 If your drawing includes tooth geometry, tolerances, and material/heat-treat requirements, we can quote → make samples → then move to bulk after approval. Clear “first article” validation is commonly used to confirm the first produced part meets requirements before scaling up. When a sample helps A sample helps when:• Tooth data or tolerances are missing on the drawing• You’re replacing an existing part and need match-fit to mating parts• You want to benchmark wear/noise/backlash performance using a “known good” reference What we need to quote accurately 1. Drawing (2D/3D) or sample + photos of mating parts2. Gear data (module/DP, teeth, pressure angle, helix angle if any, face width)4. Material & heat treatment (hardness/case depth targets if applicable)5. Accuracy/inspection requirements (dimensional + gear profile/lead if required)6. Quantity plan + Incoterms (FOB/CIF/DDP) Quick table Input Typical result Notes Complete drawing Drawing + sample Lowest ambiguity Drawing + sampleLower risk for first orderBest for match-fitSample onlyExtra measurement & confirmationMore time upfront Send your drawing/sample and quantity plan. We’ll confirm manufacturability, lead time, and the inspection pack options in the quotation.

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 scaling to production. When a drawing is enough A drawing is usually sufficient when it includes:• Tooth data (module/DP, teeth, pressure angle, helix, face width)• Datum scheme, tolerances, fits, and material/heat treat requirements• Required inspection outputs (dimensional + gear metrology scope) When we recommend adding a sample A sample helps when:• The drawing is missing tooth details or tolerance stack info• You’re replacing an existing part and need match-fit to mating parts• The application has sensitivity to noise/backlash and you want a “known good” reference What it depends on 1. Drawing completeness (geometry + tolerances + heat treat)2. Accuracy target & inspection scope (higher grade needs clearer definition)3. Mating-part uncertainty (center distance/backlash constraints)4. Revision control (frequent changes → sample helps align expectations) Quick table You provide We can do Notes Complete drawing Quote → sample → bulk Fastest, lowest ambiguity Drawing + sampleQuote with lower riskBest for first order / match-fitSample onlyReverse-engineer + confirmMore time/cost upfront Send your drawing (PDF/STEP) and tell us your quantity plan + target accuracy + heat treat. If you also have a sample, mention it—we’ll advise whether it adds value for fit verification.

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. What “sample only” typically involves When there is no drawing, the supplier must create a “manufacturing definition” by:• Measuring interfaces and tooth geometry• Rebuilding CAD/drawings• Validating fits and functional targets (noise, backlash, contact pattern where applicable) How it affects cost Cost may increase due to:• Metrology time (more measurement and verification)• Potential need for multiple samples (to separate wear from original geometry)• More iteration in prototype validation (fit/mesh test)• Additional tooling decisions (cutters/fixtures) driven by rebuilt geometry How it affects lead time Lead time often increases because you add steps before cutting chips:1. Sample receipt & evaluation2. Measurement + CAD/drawing reconstruction3. Internal review + customer confirmation4. Sample manufacturing & inspection5. Bulk after sample approval Quick table Input you have Typical impact How to reduce impact Sample only Higher engineering effort → cost/lead time ↑ Provide mating part info + multiple samples Sample + basic specsModerateShare module/teeth/center distance if knownFull drawingLowest risk & fastestLock critical characteristics early If you only have a sample, send 2–3 samples if possible, plus where it runs (gearbox model / mating gear photos). We’ll confirm the reverse-engineering scope and give you a quote with a realistic timeline.

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 often lawful when a product is legitimately obtained, but IP/trade-secret risks must be managed carefully. When we can support If you have an existing gear/shaft that needs replacement, benchmarking, or fit verification, we can:• Measure key interfaces (bore/shaft fit, runout, faces)• Measure tooth data and provide a report (when feasible)• Build a “manufacturing drawing” for quotation and production (under agreed terms) What it depends on 1. Ownership & restrictions: whether the part is yours to share and not under NDA/confidentiality2. Measurement depth: basic dimensional checks vs full gear inspection (profile/lead/pitch)3. Part condition: wear/damage may distort measured values (we may request multiple samples)4. Application context: mating part info affects how we interpret fits/backlash targets How we control quality and risk 1. Confirm the part is legitimately obtained and free of contractual restrictions2. Define measurement scope and acceptance references (what “good” looks like)3. Run measurement + issue a report; for reverse-engineered manufacturing, we’ll confirm critical interfaces with you4. If production is needed, we proceed to sample → confirmation → bulk under controlled revision Quick table Request type What you provide What you get Dimensional measurement Reverse-engineer for manufacturing Dimensional report Gear metrologySample(s) + mating part info (if possible)Tooth data report (scope-defined)Reverse-engineer for manufacturingSample(s) + application infoQuote + sample plan + controlled drawing If you’re onboarding a new supplier, send your vendor questionnaire or request an Audit Pack.

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 In practical terms, “direct manufacturer” means we manage the key production chain with our own people and equipment. Our company profile describes PairGears as a high-tech enterprise engaged in R&D, manufacturing, and sales of gears and shafts, and notes substantial in-house equipment for machining and gear processes.This matters because your order is handled with a single process owner: drawing confirmation → process route → in-process QC → final inspection → shipment release. What we still do through qualified partners As with most gear factories, some “supporting links” may be outsourced or co-processed when needed (for example, certain special surface treatments or logistics services). But the core manufacturing and quality control responsibilities remain with PairGears under our quality system and shipment release rules.

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. Note: In manufacturing, lead time usually includes setup/changeover, processing, waiting between operations, and final inspection—so it will vary with process route and inspection scope. Typical Timelines Order Type What It Means Typical Timing OEM / repeat production Tooling and process route already validated ~15 days Custom gear – samples New tooling/fixtures/cutters + first-article inspection ~30 days Custom gear – mass production After sample approval (and PPAP if required) 15–30 days What Can Change The Timeline • Tooling status: new cutters/fixtures/gauges required or not (new tooling adds time)• Process route: heat treatment + grinding + gear inspection steps (more steps = longer cycle)• Quality/approval requirements: FAI, full dimensional report, gear profile/lead report, PPAP submission level (if required)• Order volume & schedule slot: batch size and capacity reservation on critical processes (heat treat / grinding / gear inspection) How We Keep Lead Time On Track • Lock drawing revision and confirm critical characteristics before release• Milestone schedule: tooling/DFM → sample → approval → mass production (owners + checkpoints)• Capacity reservation on bottleneck operations (heat treatment, grinding, gear inspection)• First-article approval before batch release, and QA sign-off before shipmentLock drawing revision and confirm critical characteristics before release What We Need From You To Confirm Lead Time Quickly • Drawing/3D (or sample) + material & heat treatment requirement• Gear spec: module/DP, teeth, accuracy grade (ISO/DIN/AGMA), hardness/case depth target• Quantity (trial + annual volume) and target Incoterms (FOB/DDP)• Any required documents: COC/material cert/heat-treat report/gear measurement charts/PPAP Send your drawing/specs and quantity plan—we’ll confirm the exact lead time and a milestone schedule in the quotation.
