When your project demands a reliable right-angle power transfer, a poorly matched gear set can introduce backlash, noise, and premature wear that derails your build. Whether you are an engineer prototyping a robotic arm, a maker assembling a CNC axis, or a hobbyist building a custom drive train, these metal bevel gears give you the dimensional accuracy and material strength to get the job done right.
Each gear is machined from metal alloy and available in three module sizes — 1M, 1.5M, and 2M — with tooth counts ranging from 15T to 40T. The 1M module gears span approximately 15–40 mm in pitch diameter (0.59–1.57 in); 1.5M gears range from roughly 22–60 mm (0.87–2.36 in); and 2M gears cover approximately 30–80 mm (1.18–3.15 in). All variants are designed for a 1:1 ratio at a 90-degree meshing angle, ensuring smooth, low-vibration torque transmission between perpendicular shafts.
Typical use cases include right-angle gearbox assemblies for desktop CNC routers, bevel gear pairs for robotic joint actuation, and custom differential drive mechanisms in RC vehicles and automation rigs — all applications where compact 90-degree power redirection is critical.
Available in 1M, 1.5M, and 2M to match a wide range of gear pitch requirements across hobby and light industrial applications.
Engineered for perpendicular shaft drives with equal tooth counts on both gears, delivering balanced torque and speed in both directions.
Machined from durable metal alloy for resistance to deformation under load — suitable for continuous-duty drive systems in robotics and CNC builds.
Choose from 15 to 40 teeth per gear to fine-tune pitch diameter and mesh clearance for your specific shaft spacing and housing design.
Precision-cut tooth profiles minimize backlash and vibration, keeping positional accuracy tight in servo-driven and stepper-driven systems.
Standard module sizing means these gears are interchangeable with other metric-module bevel gears of the same M and tooth count, simplifying repairs and upgrades.

The module (M) defines the tooth size and pitch. A larger module means larger, stronger teeth suited for higher torque. For light-duty robotics or small mechanisms, 1M is typically sufficient. For moderate loads in CNC or automation rigs, 1.5M offers a good balance. For heavier drives or larger shaft diameters, choose 2M. Always match the module between the two mating bevel gears.
Yes. Each listing is for one single gear. For a 1:1 bevel gear pair, you need to purchase two gears of the same module and the same tooth count. Both gears will mesh at 90° to transfer rotation between perpendicular shafts at equal speed and torque.
Bore diameter varies by module and tooth count. Please refer to the variant options or contact us to confirm the bore size for your selected variant before ordering. If your shaft diameter differs, the bore can typically be enlarged by a machinist.
These metal alloy bevel gears are designed for light to moderate continuous-duty applications such as robotics joints, small CNC axes, and automation mechanisms. They are not rated for heavy industrial gearboxes. For high-torque or high-speed industrial use, please contact us to confirm suitability.
The metal alloy construction provides reasonable resistance to light moisture exposure. For environments with prolonged humidity, water, or chemical exposure, we recommend applying a light gear lubricant or grease to the tooth surfaces and bore to extend service life and prevent surface oxidation.
No. Bevel gears must be matched by module. A 1M gear will only mesh correctly with another 1M gear of the same tooth count. Mixing modules results in incorrect tooth engagement, excessive noise, rapid wear, and potential gear failure.
The pitch diameter equals the module multiplied by the tooth count (PD = M × T). Choose a tooth count so that the resulting pitch diameter fits within your housing or frame geometry. For example, a 2M 20T gear has a pitch diameter of 40 mm (1.57 in). Select the variant options above to find the combination that matches your design envelope.
