Makers, robotics engineers, and DIY automation builders rely on module 2 nylon spur gears to keep their drive trains smooth and their timelines on track.\u003c\/p\u003e\n    \u003cp\u003eThis listing includes 2 pieces of flat spur gears with a module (M) of 2 and 58 teeth. Manufactured from engineering-grade nylon (PA), these gears offer a tooth pitch of 6.28 mm (approx. 0.247 in) and an approximate pitch circle diameter of 116 mm (approx. 4.57 in). The flat blue finish aids visual identification during assembly. Bore diameter and hub dimensions vary by variant — see variant options for exact measurements.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include: DC motor pinion drives in 3D printer extruder assemblies, rack-and-pinion linear actuators for CNC router Z-axes, and low-speed reduction stages in robotic arm joints where a module 2 nylon gear pair reduces noise and eliminates lubrication requirements.\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 Designed for Module 2 (M2) gear systems.
