90° Bevel Gear Pairs — Precision Modulus Transmission Gears for Makers & Engineers

When your drivetrain needs to change direction without losing torque, a mismatched or imprecise bevel gear set becomes the weakest link in your build. Whether you're a robotics hobbyist, a CNC machine builder, or a mechanical engineering student, these 90° bevel gear pairs give you the exact modulus and tooth count combination your project demands — sold as matched pairs ready to mesh straight out of the package.

Each listing covers a wide selection of modulus values (0.5, 0.75, 0.8, 1, 1.2, 1.25, 1.5, 1.7, 1.75, 2, 2.2, 2.25, 2.5, 2.7, 3, 3.2, 4, and 5 Mod) paired with tooth counts ranging from 12T to 160T per gear, spanning gear ratios from 1:1.5 up to 1:8. The gears are machined from metal alloy stock and feature a natural metallic finish. Bore diameter and hub dimensions vary by modulus and tooth count — see variant options for exact measurements.

Typical use cases include: right-angle power transmission in DIY gearboxes and speed reducers, direction-change mechanisms in small CNC routers and laser engravers, and custom actuator assemblies for robotics arms and automated fixtures requiring a compact 90-degree bevel gear drive.

⚙️ Compatibility: Designed for standard metric modulus gear systems. Pair with matching modulus spur gears, shafts, and couplings. Bore size varies by variant — confirm shaft diameter before ordering.

✅ Key Features of These 90° Bevel Transmission Gears

📐Wide Modulus Range (0.5–5 Mod) — Covers fine-pitch miniature drives up to heavy-duty industrial-scale gearing in a single product family, so you can source the exact modulus without hunting across multiple suppliers.
🔢Broad Tooth Count Selection (12T–160T) — Gear ratios from 1:1.5 to 1:8 let you dial in the speed reduction or torque multiplication your application requires, from near-direct drive to high-reduction configurations.
📦Sold as Matched Pairs — Each set ships as a pre-matched pinion and ring gear with the correct tooth ratio, eliminating the guesswork of sourcing compatible mates separately.
🔩Precise 90° Mesh Angle — The bevel tooth geometry is cut to deliver a true right-angle power transfer, maintaining smooth engagement and minimizing backlash across the full load range.
🏗️Metal Alloy Construction — Machined from metal alloy stock for the rigidity and wear resistance needed in continuous-duty mechanical drives, outperforming plastic or resin alternatives in torque-intensive applications.
🔄Metric Modulus Standard — Fully compatible with the international metric gear standard, making integration with off-the-shelf shafts, bearings, and housings straightforward for both prototyping and production builds.

❓ Frequently Asked Questions

How do I choose the right modulus for my project?

Modulus (Mod) is the fundamental size parameter of a gear — it equals the pitch diameter divided by the number of teeth. For light-duty robotics and small mechanisms, Mod 0.5–1 is typical. For medium-duty CNC or actuator drives, Mod 1.5–2.5 is common. Heavy-duty or large-diameter applications generally use Mod 3 and above. Both gears in a meshing pair must share the same modulus.

What gear ratio should I select?

The gear ratio determines how much the output speed is reduced (and torque multiplied) relative to the input. A 1:2 ratio halves the output speed and doubles the torque. A 1:5 ratio reduces speed to one-fifth while multiplying torque fivefold. Choose based on your motor's RPM and the output speed or torque your application requires.

What shaft diameter do these gears fit?

Bore diameter varies by modulus and tooth count. Please check the specific variant's bore dimension in the variant selector or contact us to confirm before ordering. If your shaft diameter does not match the standard bore, the gear can typically be re-bored by a local machine shop.

Are these gears strong enough for continuous-duty use?

These gears are machined from metal alloy, which provides significantly greater strength and wear resistance than plastic or nylon alternatives. They are suitable for continuous-duty mechanical drives within their rated load range. For very high-torque or high-speed industrial applications, please contact us to confirm suitability for your specific load conditions.

Do these gears resist corrosion?

The gears feature a natural metallic finish without additional coating. For indoor or dry environments this is generally adequate. For humid, wet, or chemically exposed environments, we recommend applying a light machine oil or grease to the gear teeth during installation and periodically during service to prevent surface oxidation.

Can I use one gear from a pair with a gear I already own?

For two bevel gears to mesh correctly they must share the same modulus and be designed for the same pressure angle (typically 20°). If your existing gear matches these parameters and the tooth count combination gives your desired ratio, it is possible to use a single gear from this listing. However, we recommend purchasing a matched pair to ensure consistent tooth geometry and optimal meshing performance.

What is the difference between ordering "1 Pair" and "1 PCS"?

"1 Pair" includes both the pinion (smaller gear) and the ring gear (larger gear) as a matched set — everything you need for one right-angle drive stage. "1 PCS" means a single gear only, which is useful if you need a replacement for one half of an existing pair or are building a custom assembly where you already have the mating gear.
