When your drive system demands a reliable 90° power transfer and you can't afford slop or misalignment, finding a matched bevel gear pair that actually fits your shaft and tooth count is frustrating. This bundle is designed for makers, robotics builders, CNC hobbyists, and mechanical engineers who need a ready-to-run mating gear set without sourcing two separate parts.
Each bundle includes a matched pinion and wheel gear pair machined to a 1:2 ratio with a 90° meshing angle. Available in Module 1.5 (M1.5) and Module 2 (M2) standards, with tooth count combinations ranging from 15+30 teeth up to 20+40 teeth. Gear outer diameters typically span 22.5–80 mm (approx. 0.89–3.15 in) depending on module and tooth count. Material is typically 45# carbon steel or brass alloy — see variant options for exact material per SKU.
Typical use cases include DIY gearbox builds requiring a right-angle drive, robotics joint actuators needing a compact 1:2 speed reduction, and CNC router or 3D printer axis drives where a 90° bevel gear set replaces a worm gear for lower backlash. Also suited for model engineering, RC vehicle differentials, and educational mechanical demonstration kits.

Module size determines the tooth size and load capacity. M1.5 gears have smaller, finer teeth suited for lighter loads and compact assemblies — common in robotics, small actuators, and model engineering. M2 gears have larger teeth that handle higher torque and are better for heavier DIY machinery, CNC drives, or applications with significant radial loads. If you're unsure, check your existing gear's module marking or measure the tooth pitch.
The first number is the pinion (smaller, faster-spinning gear) and the second is the wheel (larger, slower gear). A 15+30 or 20+40 combination always gives a 1:2 speed reduction ratio — the wheel turns at half the speed of the pinion. Choose a combination based on the center distance between your shafts and the physical space available in your gear housing.
These bevel gears are precision-machined to metric module standards and suitable for light-to-medium duty applications including robotics, DIY gearboxes, CNC machines, and model engineering. For heavy industrial or continuous high-torque applications, please contact us to confirm the rated torque and material specification for your chosen variant before ordering.
Corrosion resistance depends on the material of the specific variant. Steel variants offer good mechanical strength but may require lubrication and protection from moisture in exposed environments. If your application involves humidity or occasional water exposure, contact us to confirm the finish or material of your chosen variant, or consider adding a light gear grease for protection.
Bore diameter varies by variant. Please check the bore size listed in the variant options against your shaft diameter before purchasing. If you need a specific bore size that isn't listed, contact us — custom bore machining may be available. Also verify that the module of these gears matches any existing gears in your system, as mismatched modules will not mesh correctly.
The bundle is sold as a matched pair specifically because both gears are cut to the same module and designed to mesh together at 90°. While you can use a single gear if you already have a compatible mate, we recommend purchasing the bundle to guarantee module compatibility, tooth profile match, and correct center distance. Mixing gears from different sources risks poor meshing and accelerated wear.
For most DIY and light-duty applications, a standard gear grease or light machine oil applied to the tooth contact surfaces is sufficient. For higher-speed or continuous-duty use, a dedicated gear lubricant with EP (extreme pressure) additives is recommended. Re-lubricate periodically based on your operating conditions and inspect for wear at regular intervals.
