Engineers, robotics builders, and DIY CNC makers who rely on module 2 gear trains need components that hold tight tolerances across every tooth — these cylindrical spur gears are machined to meet that standard.\u003c\/p\u003e\n    \u003cp\u003eEach gear in this series follows Module 2 geometry with a tooth pitch of 6.28 mm (0.247 in). The tooth count range spans 12T through 26T, yielding outer diameters from 28 mm (1.10 in) to 56 mm (2.20 in). Material is typically engineering-grade metal alloy; finish and exact alloy grade vary by variant — see variant options for confirmation.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include motor pinion assemblies in DC gear-motor drives, rack-and-pinion linear actuators for DIY CNC routers, and stage-reduction gearboxes in robotics and automation rigs where a compact 2Mod spur gear pair delivers the required speed ratio.\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 (Mod 2) gear systems.
