Your gearbox lives or dies by its shafts. We machine them to your exact drawing—no redesigns, no substitutions. Every shaft is verified before shipment, not after. If the print says Ø12.000 mm, that is what you get.
We are BQUQ, a precision manufacturing factory in Dongguan, China. We have run CNC lines for 20 years. Your drawings go straight to the shop floor. No sales layers, no delays.
At a glance: ±0.005 mm machining tolerance, 7–10 day lead time, no MOQ, ISO 9001:2015, 100% inspection report per batch.

1. Batch-traceable quality. Each batch gets a unique lot number. Material heat numbers, machine operator, inspection records—all linked to that number. If a problem appears in your assembly line, we trace it back in minutes, not weeks.
2. Inspection report per batch. You do not have to trust us. Every shipment includes a dimensional report. Critical features are measured on a CMM. Hardness and surface finish are documented. You can skip incoming inspection if your QA allows it.
3. One factory for CNC + stamping + springs + heat sinks. Your gearbox shaft might need a circlip, a spring retainer, or a heat sink for the motor housing. We make all of them under one roof. Fewer suppliers, fewer logistics headaches, one point of accountability.
Where these parts are used
Our shafts go into gearboxes that run 24/7. Typical applications:
Industrial gear reducers – input and output shafts for conveyors, mixers, and cranes. High torque, high cycle life.
Automotive transmission systems – countershafts, layshafts, and differential pinion shafts. We hold tight tolerances for bearing journals and spline fits.
Robotics and servo actuators – small-diameter shafts with high precision. Backlash and runout matter at these speeds.
Agricultural machinery – PTO shafts and gearbox shafts exposed to dirt and shock loads. We use 8620 with carburizing for surface hardness.
Medical devices – miniature gearbox shafts for surgical drills and infusion pumps. Clean materials, tight tolerances, full traceability.
If your application needs a shaft that carries load, transmits torque, or locates bearings—we have machined something like it before.
Q: Do you really have no MOQ?
A: Yes. We run one prototype shaft for a customer testing a new design. We also run 100,000 pieces for production lines. Our CNC machines are flexible. You pay for the parts, not for a minimum batch.
Q: How do you guarantee ±0.005 mm tolerance?
A: We machine to the drawing, then measure. Critical diameters and runouts are checked on a CMM with a resolution of 0.001 mm. The inspection report is included with every shipment. If a part is out of spec, it does not leave the factory.
Q: What is your typical lead time?
A: Prototypes ship in 7 days. Production batches in 10–14 days, depending on heat treatment and grinding steps. We quote a firm lead time with your price. We hit it—or we tell you before it slips.
Q: Can you provide material certificates?
A: Yes. We supply mill certificates for all raw materials. Heat treatment reports and hardness curves are available on request. All documents are in English.
