When your motion-control build demands quiet operation and corrosion-free reliability, metal gears often create unnecessary noise, weight, and maintenance overhead. Makers, robotics engineers, and small-machine builders who need a dependable, low-friction drive solution will find these nylon spur gears a practical drop-in choice across a wide range of shaft sizes and gear ratios.
Each gear is machined from engineering-grade nylon in a distinctive blue finish. The Mod 1 tooth profile is compatible with all standard Mod 1 mating gears and racks. Tooth counts span 15 to 150 teeth, and bore diameters range from 4 mm (0.16 in) to 16 mm (0.63 in), covering the most common motor and shaft sizes used in hobby CNC, 3D-printer extruder drives, and light automation equipment.
Typical use cases include stepper-motor pinion drives on desktop CNC routers, gear-reduction stages in robotic arm joints, conveyor-belt tensioning assemblies, and educational robotics kits where a nylon Mod 1 spur gear with a 4–16 mm bore delivers the right balance of strength and weight savings.
Manufactured from durable nylon with inherent self-lubricating properties, reducing friction and wear without additional grease in most light-duty applications.
A single product family covers gear ratios from high-speed pinion (15T) to large reduction wheels (150T), eliminating the need to source from multiple suppliers.
Ten bore diameter options (4, 5, 6, 7, 8, 10, 12, 14, 15, 16 mm) accommodate the most common stepper motor shafts, servo output shafts, and standard metric round stock.
Fully interchangeable with any Mod 1 rack, pinion, or mating gear — a globally recognised standard used in CNC, robotics, and light industrial machinery.
Nylon absorbs impact and dampens gear-mesh vibration, making these gears well-suited for noise-sensitive environments such as desktop machines and educational labs.
Unlike steel gears, nylon does not rust and resists mild oils, greases, and common workshop chemicals, extending service life in humid or lightly contaminated environments.

Select the tooth count based on your required gear ratio. Divide the driven gear tooth count by the driving gear tooth count to get the reduction ratio. For example, pairing a 15T pinion with a 60T wheel gives a 4:1 reduction. Smaller tooth counts (15–25T) are typically used as motor pinions; larger counts (60–150T) are used as driven wheels or for large reduction stages.
Match the bore diameter to your motor or drive shaft diameter. Common stepper motor shaft sizes are 5 mm and 8 mm; servo shafts are often 6 mm or 8 mm. Measure your shaft with a calliper before ordering. If your shaft is slightly undersized, a set screw or shaft collar can compensate for minor clearance.
Yes. All Mod 1 gears share the same tooth profile and pitch, so these nylon gears mesh correctly with steel, aluminium, or brass Mod 1 counterparts. Keep in mind that pairing nylon with metal will result in the nylon gear wearing faster over time — this is often intentional, as the nylon acts as a sacrificial component to protect more expensive metal parts.
Engineering-grade nylon (PA) offers tensile strength typically in the range of 70–85 MPa, which is sufficient for light-to-medium duty applications such as desktop CNC, 3D printers, and small robotic joints. For high-torque or heavy-load applications, metal gears are recommended. Nylon gears excel where low noise, low weight, and corrosion resistance are priorities over maximum load capacity.
Nylon is inherently self-lubricating, so these gears can run dry in most light-duty applications. For extended service life under moderate loads, a light application of PTFE-based dry lubricant or white lithium grease is recommended. Avoid petroleum-based oils, which can degrade nylon over time.
The blue pigment is blended into the nylon material and does not affect mechanical properties or dimensional tolerances. All gears are machined to standard Mod 1 specifications regardless of colour. The blue finish also makes it easy to visually identify these gears within a mixed drivetrain assembly.
Nylon is corrosion-resistant and performs well in humid conditions. However, nylon can absorb moisture over time, which may cause slight dimensional changes (typically <0.5% linear expansion). For outdoor or high-humidity applications, allow for this tolerance in your design, or consider sealing the gear housing to minimise moisture exposure.
