Module 1.5 Blue Nylon Spur Gear — Low-Noise Pinion for Stepper Motors, Robotics & DIY Drives

Builders and engineers who run stepper motors, servo drives, or custom gearboxes know the frustration of metal-on-metal gear noise and the added weight that comes with steel pinions. When your project demands quiet, lightweight power transmission with enough strength for moderate loads, a nylon spur gear is the practical choice. This Module 1.5 blue nylon spur gear is designed for exactly those applications — from desktop CNC machines and 3D printer extruder drives to robotic arm joints and educational automation rigs.

Each gear is injection-moulded from engineering-grade nylon (PA66), giving it a distinctive blue colour that makes it easy to identify in multi-gear assemblies. The module is 1.5 (metric), with tooth counts ranging from 12T to 60T and bore diameters from 6 mm to 12 mm (approximately 0.24 in to 0.47 in). The outer diameter scales with tooth count: a 12T gear measures approximately 21 mm (0.83 in) OD, while a 60T gear reaches approximately 93 mm (3.66 in) OD. Gear face width is typically 15 mm (0.59 in). Each unit is sold individually (1 Pcs per pack).

Typical use cases include stepper motor pinion drives in CNC routers and laser engravers, reduction gear stages in small robotic joints and servo-driven mechanisms, and replacement or prototype gears in educational robotics kits and maker projects. The nylon construction also makes these gears suitable for food-safe or corrosion-sensitive environments where metal gears would be impractical.

⚙️ Compatibility: Module 1.5 metric standard — meshes with any other Module 1.5 spur or rack gear. Bore sizes 6 mm, 8 mm, 10 mm, and 12 mm suit common NEMA 17 / NEMA 23 stepper motor shaft diameters. Set-screw or press-fit mounting recommended; keyway not included.

✅ Key Features of These Module 1.5 Blue Nylon Spur Gears

  • 🔵Wide Tooth Count Range — Available from 12T to 60T in a single module standard, letting you dial in your exact gear ratio without switching to a different module series.
  • 🔇Low-Noise Nylon Construction — PA66 engineering nylon runs quietly against metal or nylon mating gears, reducing vibration and acoustic noise in sensitive applications like desktop CNC and lab automation.
  • ⚖️Lightweight Design — Nylon is significantly lighter than steel or aluminium, reducing rotational inertia and easing the load on stepper motor drivers in high-cycle applications.
  • 📐Multiple Bore Options — Bore diameters of 6 mm, 8 mm, 10 mm, and 12 mm cover the most common motor shaft sizes, with larger bores available on higher tooth-count variants.
  • 🛡️Corrosion and Chemical Resistance — Nylon resists moisture, mild oils, and common workshop chemicals, making these gears suitable for humid or lightly lubricated environments without surface treatment.
  • 🔩Module 1.5 Metric Standard — Fully interchangeable with any Module 1.5 rack, pinion, or mating gear, ensuring drop-in compatibility with standard metric drive systems.

❓ Frequently Asked Questions

How do I calculate the outer diameter for a specific tooth count?

For a Module 1.5 spur gear, the outer diameter (OD) = (Number of Teeth + 2) × Module = (T + 2) × 1.5 mm. For example, a 20T gear has an OD of 33 mm, and a 40T gear has an OD of 63 mm. Use this formula to verify clearance in your housing before ordering.

Which bore size should I choose for a NEMA 17 stepper motor?

NEMA 17 stepper motors typically have a 5 mm output shaft. The closest available bore in this range is 6 mm, which can be used with a 5-to-6 mm shaft adapter sleeve or by reaming the bore to 5 mm. For NEMA 23 motors with an 8 mm shaft, select the 8 mm bore option directly.

Can these nylon gears mesh with metal (steel or aluminium) gears?

Yes. Module 1.5 nylon gears mesh correctly with any Module 1.5 metal gear of the same pressure angle (20°). In mixed nylon-metal pairings, the nylon gear acts as the sacrificial wear component, which is often desirable to protect more expensive metal parts. Ensure adequate lubrication-free or light-oil lubrication for best results.

What load can these gears handle?

PA66 nylon gears at Module 1.5 are suited for light-to-moderate torque applications — typically up to 2–5 Nm depending on tooth count, speed, and operating temperature. They are not recommended for high-torque industrial drives or continuous operation above 80°C. For higher loads, consider a metal gear of the same module.

Do I need to lubricate these gears?

Nylon gears are self-lubricating to a degree and can run dry in low-speed, low-load applications. For higher speeds or continuous duty, a light application of white lithium grease or PTFE-based lubricant extends gear life and reduces wear. Avoid petroleum-based oils that may degrade nylon over time.

How do I select the right gear ratio for my stepper motor drive?

Gear ratio = Driven Gear Teeth ÷ Driver Gear Teeth. For example, pairing a 12T pinion on the motor with a 60T output gear gives a 5:1 reduction, multiplying torque by 5 while dividing speed by 5. Choose your ratio based on the required output torque and speed for your application, then select the corresponding tooth counts from the available variants.

Are these gears suitable for 3D printer or CNC router builds?

Yes. Module 1.5 nylon spur gears are commonly used in extruder drives, Z-axis lead screw couplings, and lightweight gantry reduction stages in desktop 3D printers and small CNC routers. Their low noise and self-lubricating properties make them well-suited for these applications. Verify bore size matches your motor shaft before ordering.
