· Product Overview
These mini precision spur pinion gears are professionally manufactured via high-precision CNC machining and gear hobbing, adopting high-quality metal materials with strict dimensional control. Featuring standard straight tooth profiles, concentric hollow bores, and integrated shaft sleeves, they are designed for micro power transmission, speed regulation and torque delivery in small precision mechanical systems. With stable meshing, low noise, high concentricity and excellent wear resistance, these pinion gears are ideal core transmission components for compact equipment, ensuring long-term stable operation and precise matching.
· Core Specifications
Material Options
- 45# Carbon Steel: High strength, good toughness, affordable, suitable for general industrial micro transmission;
- 304/316 Stainless Steel: Corrosion-resistant, rust-proof, suitable for humid, medical and food-grade environments;
- 20CrMnTi Alloy Steel: After heat treatment, it has high wear resistance and fatigue resistance, for high-load transmission scenarios.
Manufacturing & Technical Standards
- Compliance: ISO 6336 (Gear strength standard), GB/T 1357 (Cylindrical gear standard), ISO 9001 quality certification;
- Machining Process: CNC turning + gear hobbing / 5-axis CNC milling;
- Precision Grade: ISO 7-9 (standard), customizable to ISO 5-6 for high-precision demands;
- Dimensional Tolerance: Bore tolerance ±0.005mm, gear runout ≤0.01mm, module range: 0.5-2.0M (customizable);
- Surface Treatment: Natural finish, quenching & tempering, passivation, black oxide (customizable);
- Structure: Straight spur gear, integrated hub & bore, single-piece integrated molding.
· Application Scenarios
These micro pinion gears are widely used in small precision transmission equipment and compact mechanical systems:
- Micro motors, small reducers and portable power tools;
- Robotic joints, micro robot transmission systems and UAV accessories;
- 3D printers, CNC engraving machines and other desktop precision equipment;
- Medical inspection instruments, laboratory micro-mechanical devices;
- Hobby model cars, aircraft models and precision toy transmission parts;
- Automated assembly lines, micro sensors and small industrial automation components.
· Production Process Introduction
- Raw Material Cutting: Select qualified metal bars, cut to fixed length according to gear size;
- CNC Rough Turning: Machine the outer circle, hub and basic shape to reserve finishing allowance;
- Gear Forming: Adopt precision gear hobbing or CNC milling to form standard straight tooth profiles, ensure tooth accuracy and meshing performance;
- Heat Treatment (Optional): Quenching, tempering or carburizing to improve surface hardness and wear resistance for high-load gears;
- Finishing & Deburring: Fine turning the bore, polishing and removing burrs to ensure smooth surface and high concentricity;
- Quality Inspection: Use CMM, gear measuring instrument to detect tooth profile, runout, bore size and tolerance;
- Surface Treatment (Optional): Passivation, anti-rust treatment or coloring according to customer requirements;
- Final Inspection & Packaging: Full-size re-inspection, then package for shipment.
· Packaging and Shipping Methods
Packaging
- Single piece protection: Each gear is packed with anti-static PE bag and pearl cotton, preventing scratch, collision and deformation;
- Bulk packaging: Classified and placed in foam-lined cartons, with partition design to avoid friction and damage between parts;
- Outer packaging: Standard export corrugated cartons, with moisture-proof and shock-proof treatment, suitable for long-distance transportation.
Shipping Methods
- Express Shipping (DHL/FedEx/UPS): 3-7 working days, for prototype, small-batch and urgent orders;
- Air Freight: 7-15 working days, for medium-batch bulk orders;
- Sea Freight: 20-35 working days, for large-volume mass production orders;
- All orders are attached with tracking number, and reinforced packaging is adopted for fragile precision parts.

· Frequently Asked Questions (FAQ)
1. What is the MOQ (Minimum Order Quantity)?
Standard MOQ: 500 pieces per specification. For prototype and sample orders, we accept 10-50 pieces (sample fee applicable). Custom special specifications start from 200 pieces.
2. What is the production lead time?
Sample lead time: 3-7 working days; Standard mass production: 7-15 working days; Custom high-precision gears with heat treatment: 15-25 working days. Expedited service is available for urgent orders (additional charges apply).
3. Do you provide customization service?
Yes, full customization is supported: gear module, number of teeth, inner bore diameter, hub size, material type, surface treatment, precision grade and structural shape can all be customized according to your 2D drawings (DXF/PDF) or 3D files (STEP/IGS).
4. Can you control the gear precision and meshing effect?
Our gears are processed by professional gear hobbing machines and CNC centers, with precision up to ISO 7 grade as standard. We provide gear detection reports to ensure stable meshing, low noise and accurate transmission.
5. What surface treatments are available?
We offer natural finish, passivation, black oxide, quenching & tempering, electroplating and other surface treatments, which can be selected according to your application environment (anti-rust, wear-resistant, decorative).
