COMPANY DETAILS
Focus on Precision Gears for 20+ Years
PairGears is a technology-driven precision gear manufacturer focused on the R&D, manufacturing, and sales of transmission gears and shafts for trucks, passenger vehicles, agricultural machinery and construction equipment. We pair application engineering with robust production to deliver reliable gearbox components built for high torque, long duty cycles, and demanding field conditions.
Over the years, we have built a vertically integrated operation with 300+ sets of equipment, including CNC lathes, gear hobbing and shaving machines, gear grinders, and in-house heat-treatment lines. Our production and metrology systems—sourced from Germany, the United States, and Japan—underpin consistent quality and strong development capability in gear design, process optimization, and measurement.
Gear Machining Service
BROACHING
High-throughput broaching of internal/external splines and keyways; consistent profiles for precise shaft–hub fits.
GRINDING
Finish grinding to ISO Grade 4–6; improves finish, cuts noise, boosts load/contact uniformity—ideal for high-speed, high-load.
HOBBING
Flexible hobbing for spur/helical gears; stable indexing with consistent pitch and tooth form for volume runs.
HEAT TREATMENT
Carburizing, induction hardening, and nitriding with controlled case depth for hardness and core toughness.
LASER CUTTING
Rapid laser blanking and feature cutting; clean edges, minimal HAZ—ideal for prototypes and small batches.
SHAPING
Shaping for internal teeth, splines, blind hubs; keeps form/concentricity under constraints—for small batches, complex parts.
SHAVING
Pre-finish shaving refines flank topology, lowering noise and improving accuracy before heat-treat/grinding.
MILLING
CNC milling of blanks and datum faces; precise allowance and concentricity for downstream gear machining.
Precision Gear Customization Process
Step 1 — Requirement Collection
Customers share design requirements for custom precision gears and shafts—drawings, specs, load cases, or samples.
Step 2 — Drawing Design
PairGears runs DFM, optimizes geometry from 2D/3D or samples, then sends transmission gear drawings for confirmation.
Step 3 — Product Quotation
After drawings are confirmed, we provide an accurate quote covering material, heat treatment, tolerances, and delivery for precision gears.
Step 4 — Tooling & Mold Making
Upon price confirmation, we produce tooling/fixtures/molds. Tooling costs are paid upfront and refunded after bulk orders.
Step 5 — First Sample Approval
First-article sample in ~30 days for inspection and functional tests; customer checks fitment and gives feedback until approval.
Step 6 — Mass Production
With the approved sample, PairGears schedules batch manufacturing of precision gears and shafts to meet your demand plan.
Step 7 — Finished-Product Inspection
Inspect hardness, key dimensions, runout, tooth profile/lead, surface roughness to ensure 100% compliance; full reports provided.
Step 8 — Shipping Arrangement
After QC pass and customer confirmation, we book and ship globally for ag machinery, truck, and construction gearbox parts.

FAQ
Q: Which truck platforms are supported?
A : We cover ZF, Eaton/Fuller, Mercedes-Benz, Volvo, Scania, IVECO, DAF, Volkswagen, Sinotruk, MAN manual/AMT platforms. Fitment by OEM part number and gearbox model.
Q: What gear/shaft types do you supply for heavy-duty trucks?
A : We supply spur/helical/bevel/worm gears, synchronizers, input/intermediate/output shafts, crown wheel & pinion sets, PTO gears, planetary gear sets, differential gears.
Q: What materials and heat treatments are used for Truck gears?
A : Materials include 20MnCr5, 20CrMnTi, 18CrNiMo7-6, 42CrMo; heat treatments carburizing, induction hardening, nitriding, followed by tempering and grinding/superfinishing for load and wear resistance.
Q: How do you ensure accuracy grades and inspection?
A : We meet ISO 1328 targets: typically Grade 6–8 for shaved gears and Grade 4–6 for ground gears. Reports include profile/lead, runout, over-pins/balls span, spline gauges, with full records.
Q: What are the MOQ and lead times?
A : We support MOQ = 1 pc for prototypes and spares. Typical timing: samples 2–3 weeks, production 3–6 weeks depending on drawings, materials and heat treatment; capacity can be reserved in peak seasons.
Q: How to confirm fitment with our truck/gearbox?
A : Three ways:
(1) search by OEM P/N;
(2) verify by machine/gearbox model + position;
(3) send a sample or drawing (module, teeth, pressure angle, helix, face width, hardness, profile shift, etc.) for reverse-measurement and validation.
Q: Do you cover both early and current production classic models?
A : Yes. We have long provided compatible replacement gears for both early and currently manufactured models, and we continuously update our database.
Q: What Accompanying Quality Inspection/Technical Documents Can You Provide?
A : We can provide documents such as hardness test records, critical dimension inspection reports, material and heat treatment certificates, etc., according to the project, to meet the compliance requirements of truck spare parts channels and OEMs/Tier 1 suppliers.
