Makers, robotics engineers, and 3D-printer builders who need a reliable 1-module 50-tooth spur gear with a stepped bore find that this blue nylon plastic gear delivers the dimensional accuracy and chemical resistance their builds require — without the weight penalty of steel or aluminum.\u003c\/p\u003e\n\u003cp\u003eEach gear is machined from engineering-grade PA (nylon) in a distinctive blue color, offering a tooth count of 50 and a module of 1 (1M). The stepped bore accommodates shaft diameters from 6 mm (~0.24 in) up to 20 mm (~0.79 in), with bore options at 6, 8, 10, 12, 14, 15, 16, 17, 18, 19, and 20 mm. The outer diameter is approximately 52 mm (~2.05 in) and the face width is typically 10–15 mm (~0.39–0.59 in), consistent with standard 1M gear geometry.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include low-noise conveyor drive systems where metal-on-metal contact is undesirable, lightweight robotic arm joints requiring a 1-module 50-tooth plastic pinion gear, and DIY CNC or 3D-printer extruder drives where a stepped-bore nylon spur gear simplifies shaft fitment without set-screw slippage.\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 any standard Module 1 (1M) spur gear or rack.
