Engineers, robotics builders, and RC hobbyists who need a compact 60-tooth spur gear with a reliable bore fit will find this 0.5 module brass pinion gear engineered for exactly that purpose.\u003c\/p\u003e\n\u003cp\u003eThis gear is machined from brass, offering a balance of machinability, moderate corrosion resistance, and low-noise meshing characteristics. The module is 0.5 (Mod 0.5), with 60 teeth and a pitch diameter of 30 mm (approximately 1.18 in). Bore options range from 4 mm to 15 mm (approximately 0.16 in to 0.59 in), covering the most common motor shaft diameters in this class. Overall gear width is typically 5–8 mm depending on bore variant.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include: small DC motor gearboxes in robotics and automation rigs requiring a 0.5 mod 60T reduction stage; RC car and truck transmission pinion replacement where a brass gear reduces noise versus steel; and precision instrument drives, camera pan\/tilt mechanisms, and DIY CNC axis drives where low backlash and smooth tooth profile are critical.\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 standard Mod 0.5 spur, rack, and pinion gears.
