Whether you're a robotics hobbyist, a CNC builder, or a mechanical engineering student, mismatched gears waste time and kill torque efficiency. These POM plastic bevel gear sets are sold as matched 1:1 pairs, ready to drop into your drivetrain.\u003c\/p\u003e\n    \u003cp\u003eEach set consists of two identical bevel gears machined from POM (polyoxymethylene) acetal, a self-lubricating engineering plastic known for its low friction, dimensional stability, and resistance to wear. Available in Module 1 and Module 1.5, with tooth counts of 20, 25, or 30 per gear, and bore sizes ranging from 5 mm (0.20 in) to 12 mm (0.47 in). The 90° mesh angle delivers a true miter configuration with a 1:1 speed and torque ratio between the two shafts.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include small robot joint drives requiring a 90° axis change, compact CNC axis gearboxes where a bevel miter gear pair replaces a worm stage, and DIY automation projects such as conveyor corner drives or camera pan-tilt mechanisms.
