When a mechanical build demands a clean 90-degree change of direction, a mismatched or worn gear pair causes vibration, noise, and premature failure — frustrating for engineers, hobbyists, and robotics builders alike. This 2Pcs 2.0 Mod Bevel Gear 90 Degree Pairing Set is designed to eliminate that problem with a factory-matched 15T and 30T gear pair that meshes straight out of the box.
The set includes one 15-tooth pinion gear and one 30-tooth ring gear, both machined to Module 2.0 (Mod 2) specification. The gears are constructed from metal — typically carbon steel or brass alloy — with a smooth machined finish. Bore diameter is sized to fit standard shafts, typically in the 5–8 mm (0.20–0.31 in) range depending on the variant selected. Overall gear outer diameter ranges approximately 34–64 mm (1.34–2.52 in) across the pairing.
This 2.0 mod bevel gear set suits a wide range of applications: DIY CNC machine axis drives, RC vehicle differential assemblies, small industrial conveyor right-angle drives, and robotics joint mechanisms requiring a 2:1 gear reduction at 90 degrees.

Module (Mod) is the standardized unit that defines gear tooth size. A Module 2.0 gear has a tooth pitch of 2 mm per tooth. This matters because two gears must share the same module to mesh correctly. These bevel gears are Mod 2.0, so they are compatible with any other Mod 2.0 bevel gear in your system.
The gear ratio is 2:1. The 15-tooth pinion drives the 30-tooth ring gear, which means for every two rotations of the input shaft, the output shaft completes one rotation — doubling the torque at half the speed. This makes it well-suited for applications requiring controlled force output.
Bore diameter varies by variant. Please check the variant options above for the exact bore size. Common bore sizes for Mod 2.0 bevel gears in this tooth range are typically 5 mm, 6 mm, or 8 mm. If you need a specific bore not listed, contact us to confirm availability.
These gears feature a machined metal construction with a corrosion-resistant surface treatment, making them suitable for workshop, light industrial, and indoor mechanical environments. For prolonged outdoor or high-humidity exposure, we recommend applying a light machine oil or grease to the tooth surfaces as part of regular maintenance.
This listing is sold as a matched 2-piece set (1 × 15T pinion + 1 × 30T ring gear). The gears are factory-paired to ensure consistent backlash and tooth contact. While each gear is a standard Mod 2.0 bevel gear and will mesh with other Mod 2.0 counterparts, purchasing the matched set is recommended for optimal performance.
This 2.0 mod bevel gear 90 degree pairing set is commonly used in: DIY CNC machine axis drives, RC vehicle and robot differential assemblies, small conveyor right-angle drive systems, 3D printer Z-axis or extruder mechanisms, and general mechanical prototyping where a 90-degree power transmission with a 2:1 reduction is needed.
Select based on your shaft diameter first — the bore must match your drive shaft. Then confirm the outer diameter fits within your housing or frame clearance. If you are unsure, measure your existing gear or shaft and compare against the variant specifications listed above, or contact us with your dimensions.
