What are the initial design consulting fees for custom gearbox and gear motor solutions?

Generally, there are none. As a professional spur gearbox and planetary gearbox supplier, we do not charge initial design consulting fees for most projects. In addition, we keep non‑recurring engineering (NRE) charges and tooling costs to a minimum for standard and semi‑customized gearbox designs. For fully customized high‑precision gearbox prototypes tailored to unique application requirements, we provide transparent pre‑project cost breakdowns without hidden charges, ensuring predictable budgeting for your R&D and mass production phases.

What is your response time after an inquiry is submitted?

Within 24 business hours, a dedicated member of our sales and engineering team will acknowledge your inquiry via email, WhatsApp or telephone. We will assign a professional project specialist to follow your case and keep you updated on technical evaluation, sample scheduling, quotation preparation and order progress at all times. We pride ourselves on fast, precise customer service and one‑on‑one technical support for global industrial and commercial clients.

How can your team help manage my supply chain for gearbox and gear motor bulk orders?

We provide reliable end‑to‑end supply chain management for spur gearbox and planetary gearbox clients worldwide. We offer flexible inventory management programs, including just‑in‑time (JIT) stocking and blanket order release services for long‑term OEM partners. Our global logistics solutions support sea, air and express shipping, with complete documentation for customs clearance and cross‑border delivery. We maintain stable raw material sourcing and production capacity to avoid supply shortages, ensuring consistent lead times for your mass‑production cycles.

Can you recreate or replace obsolete spur gearbox and planetary gearbox models?

Yes, we provide a specialized legacy gearbox reproduction service for discontinued motion control components. Our senior mechanical engineers can reverse‑engineer obsolete spur gear and planetary gear assemblies, matching original dimensional tolerances, torque performance, noise levels and installation specifications. We optimize material selection and gear precision to extend product service life, helping our clients eliminate component obsolescence risks and avoid costly equipment redesigns.

What product types and specialties do you focus on?

We specialize in the research, design and mass production of high‑quality spur gearboxes and planetary gearboxes, paired with brushed DC motors, brushless DC motors and stepper motors to form complete gear motor assemblies. Our core product portfolio includes:

Spur Gearboxes & Spur Gear Motors (cost‑effective, stable transmission ratio, low‑noise operation)

Planetary Gearboxes & Planetary Gear Motors (high precision, high torque, long service life, compact structure)

Custom Shaft Gear Motors with D‑shaft, Round shaft and H‑shaft options

Micro Gear Motors for robotics, smart locks, medical devices and automation equipment

We do not provide unrelated electronic components or semiconductor products, focusing all resources on motion control gear transmission solutions.

How does your customized gearbox and gear motor solution process work?

Customers can submit an inquiry via our online contact form, email our technical team, or directly reach out to our in‑house engineers to discuss project details, including required gear ratio, torque output, operating voltage, installation size and application environment. We encourage you to upload dimension drawings, performance requirements or existing product samples to help our team quickly define your customized specifications.

Our engineers will collaborate closely with your procurement and R&D teams to optimize gearbox structure, gear material, bearing type and motor matching. We will provide formal 2D dimension drawings, 3D structural renderings, detailed performance parameters and competitive pricing proposals for your review.

Once the technical design is confirmed, our production team manufactures pre‑production samples with strict quality inspection. After sample delivery, we support full performance testing, including torque, noise, temperature rise and durability assessments. We adjust gear precision, bearing configuration or housing design according to your feedback to meet strict application standards.

After sample approval, we transition smoothly to mass production following your purchase orders. Our quality control system inspects every batch of spur gearboxes and planetary gearboxes before delivery, and our logistics team arranges on‑time shipment matching your production schedule.

Why do you not provide a full online product catalog?

While many gearbox suppliers only sell standard off‑the‑shelf products, we focus on customized motion control solutions for diversified industrial needs. Our case study page showcases successful spur gearbox and planetary gearbox projects for smart home, medical, robotics and automation industries, serving as our solution catalog. You may email us to request detailed product datasheets, gear ratio tables and technical drawings.

For standard ready‑to‑ship micro gear motors and small gearboxes, you can browse our online product list. For complete technical parameters of our mainstream spur and planetary gear motor series, please check our motor and gearbox database.

Do you have in‑stock spur gearbox and planetary gearbox products?

We maintain spot inventory for our standard‑spec micro spur gear motors and planetary gear motors for small‑batch trial orders and prototype testing. Most of our semi‑customized and fully customized gearbox products are built‑to‑order (BTO) to match unique application demands. For long‑term OEM customers, we provide JIT inventory stocking services under blanket purchase orders, reserving production capacity and raw materials to guarantee stable supply for large‑volume repetitive orders. Our minimum order quantity (MOQ) for standard gear motors is 100 pieces, with flexible negotiation for customized high‑precision models.

How do I submit an inquiry for gearbox and gear motor customization?

We offer multiple convenient inquiry channels for global clients. You can fill out our dedicated gear motor inquiry form on our website to list your gear ratio, torque, voltage, size and customization requirements clearly, enabling our team to prepare targeted solutions quickly. You may also send emails with your technical requirements or directly communicate with our professional engineers via phone. For fast standard product selection, use our online gear motor selection guide to filter suitable spur or planetary gear motor models for your application scenarios.

What is the difference between your gearbox supply service and traditional component distributors?

We are a professional manufacturer and solution provider of spur gearboxes and planetary gearboxes, rather than a simple component distributor. Traditional distributors only supply fixed standard products with limited customization support. Our in‑house engineering team optimizes gear tooth precision, gearbox material, transmission efficiency and motor matching based on your specific application needs. We tailor‑make semi‑customized and fully customized gear motors from existing mature design frameworks, delivering stable, cost‑effective motion control solutions that fit your equipment perfectly.

Why choose us as your long‑term spur gearbox and planetary gearbox supplier?

Our professional engineering support, strict quality control and customer‑oriented service make us a trusted global gearbox supplier. We adopt a collaborative development model for every project, solving motion‑control‑related challenges at the component level for our clients. We do not merely sell gearbox products, but provide one‑stop customized solutions to improve your equipment performance and reduce long‑term costs.

With years of experience in micro gearbox and gear motor manufacturing, we continuously deliver cost‑effective, high‑quality spur and planetary gear solutions for global OEM and automation clients. Our products meet international precision standards, with strict quality testing covering noise, torque stability, service life and temperature resistance. We keep up with global motion control industry trends and standards, supporting both small‑batch prototype orders and large‑scale mass production for enterprises of all sizes, helping our partners improve product competitiveness and market productivity.
