The 1 Mod 16 Teeth Blue Nylon Spur Gear is engineered for exactly these applications — delivering a clean Module 1 tooth mesh on 4 mm or 5 mm shafts, where metal gears would add unnecessary weight and acoustic noise to sensitive mechanisms.\u003c\/p\u003e\n    \u003cp\u003eThis stepped-bore nylon spur gear is formed from engineering-grade blue nylon (PA-class polymer), combining dimensional stability with inherent self-lubrication and resistance to oils and mild chemicals. The gear carries 16 teeth at Module 1, giving a pitch diameter of 16 mm (approx. 0.63 in) and an outer diameter of approximately 18 mm (0.71 in). The stepped bore accommodates shaft diameters of 4 mm and 5 mm (0.16 in and 0.20 in) — the two most common shaft sizes found on small DC motors, micro stepper motors, and hobby servo output shafts.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include: small-ratio pinion drives on NEMA 14 and NEMA 17 stepper motor shafts in compact 3D printer extruder assemblies; gear-train stages in tabletop robotics arms and wheeled platforms where a 1 Mod 16-tooth nylon pinion pairs with a larger mating spur gear for speed reduction; and educational mechatronics kits requiring interchangeable Module 1 plastic gears that mesh with standard 1M racks and worm wheels.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Meshes with all Module 1 (1M) spur gears, racks, and pinions.
