These pair bevel gear sets are engineered for makers, hobbyists, and small-scale machine builders who need consistent mesh quality and repeatable torque transmission without sourcing industrial-grade components at industrial prices.\u003c\/p\u003e\n\u003cp\u003eEach set consists of a matched pinion and wheel gear pair, precision-cut from C45 medium-carbon steel for a balance of hardness and machinability. Module sizes range from 0.8 Mod to 2.5 Mod, with tooth counts spanning 15T to 160T depending on the selected specification. Gear ratios available are 1:3, 1:4, 1:5, 1:6, 1:7, and 1:8, covering a wide range of speed-reduction and torque-multiplication requirements. Bore diameter and hub dimensions vary by module — see variant options for exact measurements.\u003c\/p\u003e\n\u003cp\u003eTypical applications include DIY gearbox assemblies for stepper motor drives, right-angle transmission in 3D printer Z-axis upgrades, custom rotary indexing tables, and educational robotics platforms requiring a compact pair bevel gear with defined reduction ratios.
