This 1 Mod 22-tooth blue nylon spur gear with a stepped bore is designed for hobbyists, robotics builders, and small-machine designers who need a reliable, low-backlash pinion without the weight penalty of steel.\u003c\/p\u003e\n\u003cp\u003eEach gear is machined from engineering-grade blue nylon (PA66 or equivalent), offering a module of 1 (1M) with 22 teeth and a stepped bore ranging from 4 mm to 12 mm (approximately 0.157 in to 0.472 in). The stepped hub design allows the gear to seat securely on shafts of varying diameters without additional machining. Outer diameter is approximately 24 mm (0.94 in); face width is typically 10–15 mm (0.39–0.59 in).\u003c\/p\u003e\n\u003cp\u003eTypical use cases include 3D printer extruder drives requiring a quiet 1M pinion gear, small robotic arm joints needing a lightweight nylon spur gear with stepped bore, and DIY CNC or automation projects where a plastic pinion gear with 22 teeth reduces system noise and weight.\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 Fits standard Module 1 (1M) gear systems.
