Description

PRODUCT DESCRIPTION

Custom Ring Gears for Robotics Gearboxes
Custom Ring Gears for Robotics Gearboxes

PairGears manufactures custom ring gears for robotics gearboxes, robotic joints, and automation transmission systems based on customer drawings, samples, and technical requirements.


Ring gears are critical components in compact transmission systems where internal teeth mesh with other gears to transfer motion and torque. The internal gear geometry, module, tooth count, material, heat treatment, and accuracy grade can be customized according to gearbox design and operating requirements.


For robotic applications, gear accuracy, tooth profile, concentricity, and surface finish are important factors affecting transmission performance. PairGears provides manufacturing solutions from gear machining and heat treatment to precision inspection.


For custom gear projects, please contact us with your drawings or specifications for technical evaluation and quotation.

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
gear broaching manufacturing
BROACHING
High-throughput broaching of internal/external splines and keyways; consistent profiles for precise shaft–hub fits.
Gear Grinding manufacturing
GRINDING
Finish grinding to ISO Grade 4–6; improves finish, cuts noise, boosts load/contact uniformity—ideal for high-speed, high-load.
Gear hobbing manufacturing
HOBBING
Flexible hobbing for spur/helical gears; stable indexing with consistent pitch and tooth form for volume runs.
Gear heat treatment manufacturing
HEAT TREATMENT
Carburizing, induction hardening, and nitriding with controlled case depth for hardness and core toughness.
Gear laser cutting manufacturing
LASER CUTTING
Rapid laser blanking and feature cutting; clean edges, minimal HAZ—ideal for prototypes and small batches.
Gear shaping manufacturing
SHAPING
Shaping for internal teeth, splines, blind hubs; keeps form/concentricity under constraints—for small batches, complex parts.
Gear shaving manufacturing
SHAVING
Pre-finish shaving refines flank topology, lowering noise and improving accuracy before heat-treat/grinding.
Gear milling manufacturing
MILLING
CNC milling of blanks and datum faces; precise allowance and concentricity for downstream gear machining.
Precision Gear Customization Process
gear Requirement Collection
Step 1 — Requirement Collection
Customers share design requirements for custom precision gears and shafts—drawings, specs, load cases, or samples.
Gear Drawing Design
Step 2 — Drawing Design

PairGears runs DFM, optimizes geometry from 2D/3D or samples, then sends transmission gear drawings for confirmation.

Gear Product Quotation
Step 3 — Product Quotation

After drawings are confirmed, we provide an accurate quote covering material, heat treatment, tolerances, and delivery for precision gears.
gear Tooling & Mold Making
Step 4 — Tooling & Mold Making

Upon price confirmation, we produce tooling/fixtures/molds. Tooling costs are paid upfront and refunded after bulk orders.
gear First Sample Approval
Step 5 — First Sample Approval
First-article sample in ~30 days for inspection and functional tests; customer checks fitment and gives feedback until approval.
gear Mass Production
Step 6 — Mass Production

With the approved sample, PairGears schedules batch manufacturing of precision gears and shafts to meet your demand plan.

gear Finished-Product Inspection
Step 7 — Finished-Product Inspection
Inspect hardness, key dimensions, runout, tooth profile/lead, surface roughness to ensure 100% compliance; full reports provided.
gear Shipping Arrangement
Step 8 — Shipping Arrangement

After QC pass and customer confirmation, we book and ship globally for ag machinery, truck, and construction gearbox parts.

PairGears At The Exhibition


PairGears is a technology-driven precision gear supplier. At shows in the Americas, Europe, and Asia, we meet OEMs and distributors, listen to needs, and introduce our custom gears and shafts for agriculture, trucks, construction equipment, and EVs.

What You'll See At Our Booth


Real parts you can hold and compare—spur/helical gears, bevel sets, planetary parts, and gearbox shafts. Our team will provide a detailed introduction to the processing methods, commonly used materials and approximate delivery dates, and will also answer any questions you have.

How We Help On Site


Bring a drawing, gear photo, or rough specs. We’ll discuss feasibility, suggest practical options, and outline next steps for quotation or sampling.

Stay Updated


Our exhibition schedule, daily highlights, and recap articles will be posted in the website News section and on our social channels (LinkedIn, Facebook, YouTube). Follow PairGears for timely updates!
