Makers, robotics enthusiasts, and small-shop engineers working on CNC machines, 3D printer extruder drives, and RC drivetrains need a spur gear that holds its tooth profile under load — these 0.5 Module 40-tooth steel pinion gears are machined for exactly that purpose.\u003c\/p\u003e\n    \u003cp\u003eEach gear is cut from 45# carbon steel, offering a tensile strength typically in the 600–800 MPa range, with a hardness of approximately HRC 20–30 in the as-machined state. The module is 0.5 (pitch diameter = 20 mm \/ 0.79 in), tooth count is 40T, and bore options span 5 mm, 6 mm, 6.35 mm (1\/4 in), 8 mm, and 10 mm to suit a wide range of shaft diameters. Teeth height is available in 3 mm and 5 mm variants. Quantity packs range from 1 to 50 pieces per order.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include: compact robotic joint drives requiring a 0.5 mod gear mesh with a mating pinion; CNC router Z-axis rack-and-pinion systems where a steel spur gear outperforms plastic alternatives; and DIY motorized camera slider or conveyor builds that need repeatable, low-backlash power transmission across a 40-tooth steel spur gear stage.\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 0.5 Module (Mod 0.5) spur or rack gear.
