Direct DC Gear Motor Factory

DC Gear Motor Manufacturer — Brushless And Brushed DC Gear Motors From Cixi, Ningbo China.

Shenghe is the DC gear motor factory, not a sourcing front. The same Cixi (Ningbo) site that runs the BLDC motor production line also runs gearbox CNC machining for housings, output shafts, planet carriers, sun gears, ring gears, worm shafts and worm wheels — gear hobbing on the gear blanks, heat-treatment QA on the case-hardened 20CrMnTi components, brushed-DC motor assembly for the brushed variants, gearbox + motor final assembly with quantity-metered grease packing under controlled conditions, controller PCB SMT (BLD22010 + BLD6010 + BLDB6010 servo) and end-of-line dynamometer testing for output torque, ratio verification and noise spectrum. As a brushless dc gear motor manufacturer and dc gear motor manufacturer china-side supplier, Shenghe serves industrial OEM procurement teams sourcing BLDC variants for continuous-duty automation, AGV and packaging, plus brushed-DC variants for intermittent / cost-sensitive applications.

DC Gear Motor Manufacturer, Not Trader

The Gear Mesh Is Cut Inside The Same Building As The DC Motor Winding.

Most "DC gear motor supplier" listings on B2B marketplaces are trading companies that source the bare DC motor from one factory and the gearbox from another, then bolt them together at a third — and quote you the whole assembly with a margin on top. Shenghe runs the entire pairing in one factory: gearbox housings and output shafts CNC-machined here, gear blanks hobbed and shaved here, BLDC and brushed-DC motors wound and assembled here, gearbox + motor final assembly with grease packing here, controller PCB SMT here (for the BLDC matched-kit variants), and the end-of-line dynamometer test that verifies output torque and ratio also runs here. When the buyer asks "what's the actual output torque under continuous duty?" — the engineer answering has the dyno data on the desk, not a chain of forwarded emails.

  • No trading-company markup between gearbox + motor cost line and your quote — direct factory FOB
  • Engineering response in English on gear ratio, output torque math, IP rating, AGMA grade, matched controller pairing
  • OEM and ODM scope locked in writing — sample to volume in one factory under one PO and one HS Code 8501
  • Audit-ready production: ISO 9001 procedures, per-unit end-of-line dyno test records on every DC gear motor, gearbox teardown for buyer inspection on request
Manufacturer vs Trader vs Marketplace

The DC-Gear-Motor-Specific Differentiator.

Sourcing a DC gear motor is harder than sourcing a bare DC motor — the assembly involves two manufacturing disciplines (motor winding + gearbox machining + heat treatment + grease packing) plus a third for BLDC variants (matched controller PCB SMT + firmware parameterisation). Most factories handle one but not all. The table below frames the honest difference on the dimensions that matter when the gear motor needs to ship on spec, run on duty, and stay quiet for 20,000+ hours.

DimensionDirect Factory (Shenghe)Trading CompanyOnline Marketplace
Engineering response time Same-day to 24h, from the engineer who runs both motor and gearbox lines 2–5 days, forwarded to motor factory + gearbox factory + back Variable — generic agent reply, no engineering depth on ratio / torque math
Gearbox + motor pairing Single-source — winding, gear cut, gearbox housing, dyno test all in-house Two factories assembled by trader — pairing tolerance not always controlled Whatever the listing has — no engineering check on the pairing's actual output torque
BLDC matched controller In-house controller PCB SMT + factory firmware parameterisation against motor spec + gearbox ratio Trader's third-party controller, no firmware match Generic controller, no matching
OEM / ODM customisation depth Custom ratio, output shaft, housing, IP rating, motor winding, controller firmware, encoder integration Limited to what underlying gearbox supplier supports — usually no winding change Branding only — usually no electrical or gearbox change
Pricing transparency Direct factory price — no resale markup on gearbox, motor, or controller 10–25% markup over factory cost (often double-margined: motor + gearbox + sometimes controller) Marketplace fees + seller markup; price not always negotiable
Sample lead time 7–10 days from order, MOQ 1 unit on stock SKU 10–20 days (factory + trader handling, plus pairing assembly) Stock items only — non-stock items go via factory anyway
Inspection access Buyer welcome on site — gearbox teardown demo at assembly station; SGS / BV / Intertek supported Trader may block direct factory access; gearbox teardown rarely possible No inspection — listing-only relationship
After-sales coverage Dyno test record per unit; engineering 8D report inside 7 days; replacement seal / grease in stock Escalation through trader; root cause hard to assign between motor and gearbox supplier Marketplace dispute system; outcome rarely engineering-grade
IP protection (custom designs) NDA supported; ODM IP belongs to customer; tooling locked under contract NDA via trader — chain-of-custody less clear, especially across two factories Generally no IP protection mechanism

Gearbox Families In-House

Four Gearbox Families — Same Across BLDC And Brushed DC.

The four gearbox families Shenghe machines and assembles in-house, identical across BLDC and brushed-DC product lines. Pick the family first against your application's torque, speed, backlash and self-locking requirement; the motor side (BLDC vs brushed DC, voltage, power) and matched controller get dimensioned at quote stage.

Gearbox familyReduction ratio rangeEfficiencyBacklashSelf-lockingBest for
Planetary Single 3:1–10:1, 2-stage to 100:1, 3-stage to 500:1 ~95% per stage 10–20 arc-min single-stage standard, <5 arc-min ground-gear precision No (back-drivable) Robotics, AGV traction, precision positioning, high torque density compact envelope
Worm Single-stage 5:1–60:1 typical, up to 100:1 on selected frames 70–85% (lower at high ratio) Higher than planetary (sliding contact) Yes (lead angle <5°) Lifts, automatic doors, barriers, conveyor stops, anywhere the load must hold position de-energised
Helical / Spur (HG-series) Single-stage 3:1–10:1, multi-stage to 1000:1 ~90% per stage (helical), ~95% spur Moderate; helical runs quieter than spur No Heavy industrial conveyor, packaging machinery, continuous-duty drives where smooth quiet operation matters
Right-angle (bevel-helical hybrid) 3:1–200:1 with 90° output ~85–90% Moderate Depends on stage mix Conveyor side-drives, packaging stations, narrow machine layouts where 90° output is required by envelope

All four families share the same factory, the same QA standards, and the same dyno-bench end-of-line test. Browse per-SKU detail at Gear Motor Hub →, or by family at Planetary Gear Motor, Worm Gear Motor / DC Worm Gear Motor, Right-Angle DC Gear Motor and High-Torque Gear Motor.

6-Step DC Gear Motor Sourcing Workflow

From Sizing Brief To Container Loading In Ningbo.

The standard sourcing path Shenghe runs with new DC gear motor procurement teams. Each step has a defined deliverable and response window so the buyer-side procurement, engineering and QA teams know what to expect at every stage.

  1. Step 1 — Send the DC gear motor sizing brief. Five-number brief: bus voltage (12V–110V DC), motor type preference (BLDC for continuous duty, brushed DC for intermittent / cost-sensitive, or "recommend"), required output torque (Nm), required output speed (RPM at gearbox shaft), gearbox style (planetary / worm / helical-spur / right-angle, or "recommend"), application + target quantity. Add IP rating, mounting interface, encoder requirement and backlash spec for precision-positioning applications. Engineering replies inside 24h on standard inquiries.
  2. Step 2 — Receive engineering shortlist (1 working day). 2–3 matched DC gear motor SKUs with predicted output torque (motor continuous torque × ratio × gearbox efficiency: 95% planetary, 85–95% helical, 70–85% worm, 85–90% right-angle), predicted output speed, AGMA Q9–Q11 standard, backlash spec, IP rating, lead time per engagement model, MOQ, FOB Ningbo and CIF target port unit price. For BLDC, matched controller (BLD22010 for 24V/36V/48V, BLD6010 for 72V/110V, BLDB6010 servo) included.
  3. Step 3 — Sample order + dyno bench test (7–10 days). 1 unit MOQ stock SKU. Sample price at 100-unit tier (not retail 1-unit). DHL / FedEx / UPS 5–7 day global air transit. Buyer-side bench: actual output torque, no-load speed verifying ratio, thermal rise, audible noise, planetary backlash. Shenghe ships matching unit's dyno test record so both sides look at same numbers — match within ±5%.
  4. Step 4 — PO + production schedule (1–3 days). PI confirms SKU, quantity, tier unit price, delivery date matching SLA, Incoterm, payment terms, packaging spec, container size, force-majeure clause, 1% next-order rebate clause if Shenghe misses SLA. T/T 30% deposit triggers gearbox CNC + motor stator winding on parallel paths.
  5. Step 5 — Pre-shipment inspection (in person or video). 2 days before shipment, AQL 1.0 in-house + optional third-party (SGS / BV / Intertek / TUV) at buyer cost. Random unit teardown, oil-seal lip check, dyno-bench spot test on AQL sample, grease quantity check, packaging + labelling. Live WhatsApp / WeChat video walk-through for overseas buyers. Per-unit dyno test record on every motor; lot records on file under ISO 9001.
  6. Step 6 — Sea / air freight from Ningbo port. 20 min from Ningbo-Zhoushan port (world's #1 cargo throughput). FOB / CIF / DAP / DDP. Sea transit US LA 14–18d, EU Hamburg 30–35d, India Mumbai 12–15d. DC gear motor container loading 60–70% of bare-motor density: small frame ~2,500/20GP, ~5,500/40HQ; medium ~1,500/3,500; large ~500/1,200. HS Code 8501 (motor with gearbox).
Gear Material & AGMA Quality

Why The DC Gear Motor Mesh Lasts 20,000+ Hours.

Gear motor service life is dominated by the gear mesh and the bearings — winding burn-out is rare, gear-mesh wear and oil-seal leak are the failure modes that show up in the field. Material grade, heat treatment, AGMA quality and lubrication are the four levers that keep the mesh quiet and lubricated for the full 20,000+ hour design life on BLDC variants.

ComponentMaterialHeat treatmentSurface hardnessAGMA grade (standard)
Planetary sun gear, planet gear, ring gear 20CrMnTi case-hardening steel Carburised + quenched + tempered HRC 58–62 surface, HRC 32–40 core Q9–Q11
Helical / spur gear (HG-series) 20CrMnTi or 40Cr Carburised + quenched (20CrMnTi) or Q&T (40Cr) HRC 55–62 (case-hard), HRC 28–35 (Q&T) Q9–Q11
Worm shaft 40Cr quenched-tempered steel, ground Through-hardened + ground after heat treat HRC 45–50 + ground surface Q9
Worm wheel ZCuSn10P1 tin-bronze (sand cast or centrifugal cast) Stress-relieved HB 80–110 (sliding-friction match to worm) Q9 (matched against worm)
Output shaft 45 carbon steel or 40Cr Q&T Q&T or normalised HB 220–280 (Q&T) —
Gearbox housing Aluminium alloy ADC12 (cast) or 45 steel (machined) Stress-relieved cast / Q&T machined — —
Bearings (output shaft) GCr15 / SUJ2 bearing steel — sealed ball or tapered roller per loading Heat-treated to bearing standard HRC 60–63 Manufacturer P5/P6 standard

For low-noise (<55 dBA at 1m) or precision-positioning (<5 arc-min backlash) applications, AGMA Q12 (DIN 6) ground gears quoted as an option — adds tooling cost for the grinding pass but extends mesh life and drops noise floor by 5–8 dBA. Confirm noise spec or backlash target at sizing brief stage.

Lubrication, Sealing & IP Rating

Sealed-For-Life — With Specs On Paper.

"Sealed for life" is marketing copy on most DC gear motor datasheets. The grade, viscosity, additive package and seal type that make it actually sealed for life are below — published specs, not aspirations.

Standard Lubricant — Planetary & Helical

Lithium-complex grease NLGI grade 2, base oil viscosity ~220 cSt at 40°C, EP additive package for high-load gear-mesh duty. Operating temperature −20°C to +120°C continuous, +140°C peak. Equivalent commercial grades: Mobil SHC 460, Klüber Polylub GLY 801, SKF LGEP 2. Quantity-metered fill at the assembly station — too much grease drives churning loss and heat, too little drives wear.

Standard Lubricant — Worm

Gear oil ISO VG 220 with extreme-pressure (EP) additive, for the sliding-contact regime between worm shaft and bronze worm wheel. Heavier viscosity than grease helps reduce wear on the bronze worm wheel under high-ratio loading. Operating temperature −20°C to +100°C continuous; oil bath sealed at the housing parting line. Synthetic gear oil (PAO base) on request for cold-start or high-temperature duty.

Food-Grade NSF H1 (On Request)

Food-grade lubricant (NSF H1 registered) available on request for food-processing, beverage, dairy and pharmaceutical applications. Base lubricant is white-mineral-oil or PAO with food-safe additive package. Confirm at quote stage so we ship the right grease + oil combination on the assembly traveler. NSF H1 brand confirmed against your audit list (procurement teams in EU and North America usually specify Klüber, Lubriplate or Petro-Canada).

Standard Sealing — IP54

Double-lip oil seal on the output shaft (NBR rubber lip + spring + dust-lip), housing O-ring at the parting line, sealed bearings on the output shaft. IP54 standard from the factory — protected against limited dust ingress and water spray from any direction. Adequate for indoor industrial duty, AGV warehouse, conveyor, packaging line.

Upgrade — IP65 / IP67

IP65 with confirmed gasket upgrade (FKM seal lip for chemical resistance, double O-ring at the parting line, IP65-rated cable gland on the motor side) — for outdoor industrial duty, washdown, dust-heavy environment. IP67 for short-term submersion, marine or food-washdown — needs confirmed seal-lip material against your washdown chemistry. Quoted per project under ODM scope at /odm-bldc-motor/.

Field Maintenance Interval

Sealed-for-life on the standard range — no field re-lubrication needed for the design life of the gear motor (20,000+ hours continuous duty on BLDC variants) at 40°C ambient. For high-duty cycles running 24/7 at >50°C ambient or with shock loading, lubricant inspection every 5,000–8,000 operating hours recommended. Replacement seal kits and grease packs stocked for any frame on request — most are 5-min replacement on the field unit.

Certifications Wall

Audit-Ready Documentation On File.

The certifications industrial procurement teams ask for at quote stage. Test reports, declaration-of-conformity documents and material certificates released under NDA for procurement audit.

ISO 9001 — Quality Management

Factory quality management system ISO 9001 certified. Procedures cover supplier qualification, in-process inspection (gear runout, oil seal integrity, dyno bench QA), end-of-line test record per unit, non-conformance handling, calibration on dyno and gauge equipment, traceability per production batch.

CE Marking — EMC + LVD

Export-spec DC gear motors and matched controllers carry CE marking covering the EMC directive (electromagnetic compatibility on the motor + drive) and the LVD directive (low-voltage / safety). EMC test reports and declaration-of-conformity documents released on NDA.

RoHS — Restricted Substances

RoHS compliance covers lead, mercury, cadmium, hexavalent chromium, PBB and PBDE restrictions. Material declarations from gear-blank steel, copper wire, magnet, bearing, lubricant and cable suppliers kept on file and refreshed annually.

REACH — EU Chemical Compliance

REACH compliance documentation for EU distribution available on request. SVHC declarations refreshed against the current ECHA candidate list — DC-gear-motor-specific SVHC items focus on lubricant + sealant + bronze worm wheel content.

UL Recognition + NSF H1 Food-Grade

UL recognition on selected motor models for North American distribution on request. NSF H1 registered food-grade lubricant on request for food-processing applications. Confirm at quote stage so we ship the right model variant with matching documentation.

Per-Unit Dyno Test Record + Material Certificates

Every DC gear motor leaves the factory with an individual dyno-bench test record. Per-shipment material certificates available on request — gear blank steel grade, copper wire grade, magnet grade, bearing source, lubricant batch.

OEM & ODM Scope — DC Gear Motor

From Logo Etching To Custom Gear Ratio.

Two engagement levels for DC gear motor procurement teams that need more than a stock SKU. OEM is the customer's brand on Shenghe's design; ODM is Shenghe building from the customer's gear-train and motor specification.

ScopeOEM (your brand on our DC gear motor)Custom (mods on existing tooling)ODM (designed from your spec)
Branding Customer logo on gearbox housing + motor body, custom packaging, custom housing colour Same as OEM, plus parameter-modification details on rating plate Same as OEM, plus customer naming convention on output shaft tag
Gear ratio change Stock ratios only (3/4/5/7/10/15/20/25/30/50/70/100/150/200:1) Custom ratio on existing gear blanks (same housing + tooling, different tooth-count combination) Custom ratio with new tooth-count and new tooling — any ratio 3:1 to 1000:1
Output shaft Stock geometry only Custom diameter / length / keyway / flat / splined / D-shaft within existing CNC envelope Custom hollow-shaft, complex step geometry, beyond existing CNC envelope
Housing & mounting Stock housing Custom flange dimensions, custom bolt pattern, custom face-mount with existing turning fixtures Custom housing mould, custom mounting interface, IP67 sealing

Production MOQ 50–100 units 100–300 units 200–500 units (depending on tooling complexity)
IP protection NDA on artwork and brand assets NDA on modification spec; Shenghe owns base SKU, customer owns modification IP NDA on full design package; ODM gear-train and motor IP belongs to customer

Send the OEM artwork or modification list to the inline RFQ — engineering returns a feasibility note inside 5 working days saying "OEM feasible", "Custom feasible", "Custom feasible with minor fixture" or "reframe as ODM". See OEM BLDC Motor →, Custom BLDC Motor →, and ODM BLDC Motor → for the full engagement-model detail.

Volume Capacity & Container Loading

Production Capacity And Shipping Math For DC Gear Motors.

DC gear motor container loading runs 60–70% of bare-motor density because of gearbox housing volume and the extra packaging needed to protect the output shaft. The numbers below help procurement teams size the first PO and predict freight cost.

DC gear motor framePower + ratio bandVoltage classMonthly capacity20GP container40HQ container

130BL right-angle / heavy worm 1500W–3000W, 10:1–1000:1 72V / 110V / 220V 500–1,000 / month ~300 units ~700 units
HG-series helical-spur Multi-stage 100:1–1000:1 48V–220V 500–1,000 / month ~400 units ~900 units

Monthly capacity figures above are typical sustained throughput; scalable on advance booking. Volume buyers and distributors get tier pricing per BLDC Motor Wholesale & Distributor Program →; DC gear motor pricing follows the same wholesale tier structure as bare BLDC motors though per-unit prices differ given the added gearbox cost.
