1.5 Mod Blue Nylon Spur Gear — Lightweight Pinion Gears for Stepper Motors & DIY Automation

When your motion-control build demands quiet, lightweight power transmission without the weight penalty of metal, finding a reliable nylon spur gear in the exact tooth count and bore you need can be a real challenge. These 1.5 Module blue nylon spur gears are engineered for makers, robotics builders, and small-workshop automation projects where low noise, corrosion resistance, and easy shaft fitting are non-negotiable.

Each gear is machined from engineering-grade blue nylon (PA66 or equivalent), offering a good balance of strength, wear resistance, and self-lubrication. The module is 1.5 (tooth pitch = 4.712 mm), with tooth counts spanning 12 T to 60 T and bore diameters from 6 mm (0.24 in) to 16 mm (0.63 in). Overall gear outer diameters range from approximately 21 mm (0.83 in) for the 12 T up to approximately 93 mm (3.66 in) for the 60 T variant.

Typical use cases include stepper-motor pinion drives in 3D printers and CNC routers, rack-and-pinion linear actuators for DIY automation rigs, and lightweight gear-train assemblies in educational robotics kits where metal gears would add unnecessary mass.

⚙️ Compatibility: Designed for 1.5 Module gear systems. Meshes with any 1.5 Mod rack, pinion, or mating spur gear. Bore sizes fit standard stepper motor shafts (typically NEMA 17 / NEMA 23) and common hobby motor shafts from 6 mm to 16 mm.

✅ Key Features of These 1.5 Mod Blue Nylon Spur Gears

🔵

Engineering-Grade Nylon Construction

Made from PA66-grade nylon for reliable wear resistance, self-lubrication, and long service life in dry-running or lightly lubricated gear trains.

🔇

Low-Noise, Vibration-Damping Operation

Nylon's inherent elasticity absorbs micro-shock loads and reduces gear-mesh noise — ideal for quiet workshop equipment, desktop CNC machines, and indoor robotics.

📐

Wide Size Range: 12 T to 60 T, Bore 6–16 mm

75+ variants covering tooth counts from 12 T to 60 T and bore diameters from 6 mm to 16 mm, letting you dial in the exact gear ratio and shaft fit your project requires.

🛡️

Corrosion-Free & Chemical-Resistant

Nylon does not rust or corrode, making these gears suitable for humid environments, light chemical exposure, and applications where metal gears would degrade over time.

⚡

Direct Stepper Motor Compatibility

Bore sizes align with standard NEMA 17 (5 mm shaft) and NEMA 23 (6.35 mm / 8 mm shaft) stepper motors, as well as common hobby and servo motor shaft diameters up to 16 mm.

⚖️

Lightweight for Weight-Sensitive Builds

Nylon gears weigh significantly less than equivalent steel or aluminum gears, reducing rotational inertia and motor load — a key advantage in multi-axis robotics and flying/moving platforms.

❓ Frequently Asked Questions

How do I choose the right tooth count for my project?

Your gear ratio is determined by dividing the driven gear tooth count by the driving gear tooth count. For example, pairing a 12 T pinion with a 60 T gear gives a 5:1 reduction. Start with your required output speed and torque, then work backwards to select the tooth counts. If you are driving a rack, the linear travel per motor revolution equals π × Module × Tooth Count (in mm).

What bore size should I select for my stepper motor shaft?

Measure your motor shaft diameter precisely before ordering. Common stepper motor shaft sizes are: NEMA 17 = 5 mm, NEMA 23 = 6.35 mm or 8 mm, NEMA 34 = 12.7 mm or 14 mm. Select the bore that matches your shaft. If your shaft is between sizes, choose the smaller bore and ream or bore it to fit — do not select a bore larger than your shaft diameter.

Are these gears strong enough for my application?

Engineering nylon (PA66) spur gears are well-suited for light-to-medium duty applications such as 3D printers, desktop CNC machines, small conveyor systems, and educational robotics. They are not recommended for high-torque, high-speed, or heavy industrial applications where steel or aluminum gears would be more appropriate. For best results, keep operating temperatures below 80 °C and avoid prolonged exposure to strong acids or bases.

Will these gears corrode or rust in humid environments?

No. Nylon is inherently corrosion-free and does not rust. It also resists mild oils, greases, and many common chemicals. This makes these gears a practical choice for humid workshops, outdoor enclosures, or applications where metal gears would require frequent maintenance to prevent corrosion.

Can I mesh these gears with metal spur gears of the same module?

Yes. Any two spur gears with the same module (1.5) and pressure angle (20°) will mesh correctly regardless of material. Pairing a nylon gear with a steel or aluminum gear is a common technique — the nylon gear acts as the sacrificial wear component, protecting the more expensive metal gear and reducing noise. Ensure center distance is set correctly: Center Distance = (T1 + T2) × Module / 2.

Do I need to lubricate these nylon gears?

Nylon is self-lubricating, so these gears can run dry in many light-duty applications. For higher loads or speeds, a light application of white lithium grease or PTFE-based lubricant will extend service life. Avoid petroleum-based oils that may swell or degrade nylon over time.

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

For a standard spur gear: Outer Diameter (mm) = (Tooth Count + 2) × Module. For example, a 1.5 Mod 20 T gear has an OD of (20 + 2) × 1.5 = 33 mm (1.30 in). A 1.5 Mod 60 T gear has an OD of (60 + 2) × 1.5 = 93 mm (3.66 in). Use this formula to verify clearance in your assembly before ordering.
