Core Answer 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.

Core Answer 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 capacity” Means Production capacity generally refers to the maximum output a factory can produce over a defined time period under normal operating conditions, given available machines, labor, and resources. What Your Available Capacity Depends On Even with a stated monthly capacity, real scheduling depends on:• Part mix & complexity (gear type, size, tolerance, finishing requirement)• Process route (e.g., heat treatment + grinding + gear measurement adds time and resource load)• Bottleneck operations (when one step cannot keep up, it limits total throughput)• Inspection/documentation scope (FAI, gear profile/lead reports, PPAP if required) How We Protect Delivery We manage capacity and delivery through a controlled plan:• Lock drawing revision & critical characteristics• Confirm process route & inspection pack• Reserve capacity on critical processes (e.g., heat treatment / grinding / gear inspection)• First-article approval before batch release + QA sign-off before shipment Quick Reference Table Item Standard statement What it means for your order Monthly capacity Up to 1,000,000 gears & shafts / month Sufficient for repeat orders and ramp-ups (subject to mix & schedule) Urgent orders Supportable when a slot is available We confirm by part route + quantity + required documents Capacity confirmation After spec review Ensures the promised timeline matches bottlenecks & QC scope Send your drawing/specs + quantity plan + target delivery term (FOB/DDP). We will confirm available capacity slot and provide a delivery milestone plan in the quotation.
Core Answer 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 handling. What’s Covered Our warranty is intended to protect you from issues that come from how the part was made—for example, a confirmed manufacturing defect that leads to premature failure within the warranty window.If the issue is confirmed as a manufacturing defect, we will provide free repair or replacement. The exact remedy may depend on the part status and logistics, but we aim to resolve it quickly and keep your line running. What’s Not Covered This warranty does not cover damage caused by:• Human error, misuse, neglect, or improper installation/operation• Unauthorized modification or repair• Normal wear, accidents, or damage after receipt/handlingThese exclusions are standard in many “limited warranty” terms. Item PairGears Standard Statement Notes Warranty type Limited warranty Covers manufacturing defects Warranty period 6 months Start point per delivery/contract terms Remedy Repair or replacement After claim review Not coveredMisuse/incorrect installation/modificationCommon exclusion patternWhat to providePO/part/lot + evidencePhotos, usage conditions, inspection data When does the 6 months start? By default, the warranty period is counted from the delivery date (or as defined in your PO/contract). For project-based supply, we can align the start point to your receiving/acceptance procedure if you specify it during ordering.Practical tip: if you require “warranty from installation/commissioning,” tell us upfront so it can be written into the order terms. How to file a warranty claim 1. Send your PO number / part number / batch or lot information 2. Share photos/videos, failure description, and operating conditions 3. Provide any inspection data you have (dimensional checks, hardness, gear measurement, etc.) 4. We review and respond with the next action (repair/replacement/return analysis)To prevent the accidental delivery of non-conforming components, we follow documented non-conforming product control procedures, including identification, isolation, disposal and QA release.

What payment methods do you accept? 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 T/T (Telegraphic Transfer) refers to an electronic bank transfer used widely for cross-border payments, typically routed through bank networks such as SWIFT/correspondent banking. Our standard payment structure (30/70) After the order is confirmed, we ask for a 30% deposit to start procurement and production planning. The remaining 70% balance is due before shipment, so the goods can be released for dispatch on time. This “deposit + balance” structure is commonly used in international trade. What the final payment schedule depends on The exact timing can vary based on:• Order type (sample vs mass production; repeat vs new part)• Documentation needs (FAI, full inspection pack, PPAP if required)• Shipping terms (FOB/DDP, booking schedule)• Your internal approval workflow (PO release / finance processing time) How the payment process typically works (steps) 1. We confirm specs, quantity, Incoterms, and lead time2. We issue a Proforma Invoice (PI)3. Buyer arranges 30% deposit via T/T4. Production + inspection (and documents, if requested)5. We send shipment-ready notice + final amount6. Buyer pays 70% balance before shipment7. Goods ship and documents are shared per agreed terms To confirm the exact payment schedule for your order, send your drawing/specs + quantity + Incoterms. We’ll issue a PI and lock the timeline with your order confirmation.
Core Answer 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 mating parts, and we’ll help fill the gaps. Option A: You have drawings (fastest) A complete drawing is the most reliable way to avoid assumptions. At minimum, include datums, critical dimensions, and any functional fits (bearing seats, spline fits, runout). Many gear manufacturing guides emphasize that a successful part starts with clear geometry + material + heat treat + quality requirements. Option B: You only have a sample (still workable) If you can send a sample, also share:• Photos of the mating parts (gearbox layout if possible)• Any known specs (tooth count, center distance, ratio)• Failure mode or reason for replacement (wear, noise, broken teeth)We’ll measure and confirm the tooth data and interfaces before finalizing the quote. What the quote depends on Your final cost/lead time and manufacturability mainly depend on:• Gear accuracy grade & inspection scope (ISO/DIN/AGMA level; profile/lead/pitch/runout checks)• Material + heat treatment (carburizing/nitriding/Q&T; case depth/hardness targets)• Process route (hobbing/shaping/skiving vs grinding; whether post-heat grinding is required)• Order volume & delivery term (trial + batch, FOB/DDP; packaging/document requirements) The specific information sent to us 1) Gear data (most important)Please provide as many as you can:• Tooth count, module/DP, pressure angle, helix angle (if helical), face width• Bore/shaft interface: keyway/spline, fits, tolerances• Backlash target or center distance (if known)(These are common “must-have” tooth data fields in gear machining guidance.)2) Material & heat treatment• Material grade (or equivalent)• Heat treat type (carburize/nitride/induction/Q&T), hardness + case depth targets3) Quality & documents• Accuracy grade (ISO 1328 / DIN / AGMA), plus required reports:• Dimensional report / hardness report / material cert• Gear profile & lead chart (if required)4) Commercial info• Quantity (sample + first batch + annual volume)• Target lead time and Incoterms (FOB/DDP) Quick reference table What you provide Example items Why it matters Drawing or sample 2D/3D, photos, mating part info Avoids assumptions Gear tooth data module/DP, teeth, pressure angle, helix, face width Determines tooling + process route Material & HT 20MnCr5/8620 eq., carburize/nitride, hardness/case depth Drives strength + distortion control Accuracy & reportsISO 1328 grade, profile/lead/pitch/runout reportControls noise/life; defines inspection workloadAccuracy & reportsqty plan, lead time, FOB/DDPLocks scheduling + logistics plan Send your drawing (or sample photos) + quantity plan + target accuracy/heat treat.

Core Answer 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 time covers In practice, the stated lead time is mainly about order processing + picking/packing (for stock) or production + inspection (for non-stock), followed by shipment release.If you need “door-to-door arrival time,” that will additionally depend on shipping mode and Incoterms. What the timeline depends on • Inventory status & part mix (all items in stock vs partial stock)• Order volume & packaging requirement (carton vs pallet/crate)• Inspection/document scope (e.g., standard release vs extra inspection pack)• Shipping terms & destination (FOB/DDP affects who arranges which leg) How we keep bulk orders on schedule • Stock orders: confirmed part list → pick/pack → labeling/traceability → shipment release• Non-stock orders: drawing/spec lock → production route → in-process checks → final inspection → QA releaseWe share progress and flag any risks early so you can keep your downstream plan stable. Typical Timelines Order Type Quick reference table Notes Bulk products with inventory Ship within ~1 week Depends on quantity + packing + release docs Bulk products without inventory ~30 days Depends on process route + inspection scope Send your part list (part number/spec) + quantities + destination + Incoterms. We’ll confirm what’s in stock, the ship date, and the delivery plan in one reply.
Core Answer 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). What this timeline includes The sample phase usually covers DFM/process planning + tooling/cutters/fixtures (if needed) + machining + heat treatment (if required) + sample inspection + customer approval. Bulk lead time starts after the sample is confirmed, because key dimensions and quality criteria are locked at that point. What the final lead time depends on • Tooling / fixtures / cutters: whether new tooling is required and how complex it is• Process route: grinding, specific heat treatment, and gear metrology add steps and queue time• Inspection/document package: FAI/full dimensional report, gear profile & lead charts, PPAP (if required)• Order volume & schedule slot: batch size and bottleneck capacity (heat treat / grinding / gear inspection) How we keep customized orders on schedule 1. Lock drawing revision & critical characteristics before starting2. Release a milestone plan (tooling → sample → approval → bulk) with owners3. Reserve capacity on critical processes (heat treat, grinding, gear inspection)4. Run sample inspection/FAI before moving to bulk5. Bulk runs under QA release to keep shipment timing stable Quick reference table Stage Typical lead time First sample 15–30 daysFrom confirmed specs (drawing/sample + requirements) First sample30–45 daysStarts after sample confirmation Send your drawing (or sample photos) + material/heat-treat requirement + accuracy/report needs + quantities. We’ll confirm the sample lead time and a bulk delivery plan in the quotation.
Core Answer 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 per order. What “no MOQ” means for your order “MOQ” is often used by manufacturers to set a minimum order size so production runs remain efficient.Our policy for new development is different: we can start with low-volume prototypes so you can validate fit and performance before committing to larger volumes. Why tooling cost is required for new custom parts Even if the quantity is small, a new gear/shaft often needs dedicated cutters, fixtures, tooling, and inspection gauges to hit drawing requirements and repeatability. Tooling costs are the expenses associated with designing and making the tools/fixtures used in manufacturing. What your final MOQ / unit price may depend on While “no MOQ” applies to development, the most economical order size (and your unit price) depends on:• Tooling scope (new cutters/fixtures/gauges needed or not)• Process route (heat treat, grinding, gear measurement requirements)• Accuracy & inspection pack (FAI/full reports/PPAP if required)• Volume plan (trial + first batch + annual forecast) Quick reference table Item PairGears standard Notes MOQ for newly developed custom parts No MOQ (1 pc possible) For development and prototypes Tooling costRequired for new custom partsCutters/fixtures/gauges as neededBest unit priceUsually at higher volumeWe provide price breaks by quantity Send your drawing/sample + quantity plan. We’ll reply with a quotation including tooling cost (if any) and price breaks for batch orders.
