2 Mod Bevel Gear — 90° Precision Transmission for Makers and Mechanical Builders
When your drivetrain demands a reliable right-angle power transfer, finding a bevel gear that meshes cleanly without backlash or premature wear is a real challenge. These 2 Module bevel gears are engineered for makers, robotics builders, CNC hobbyists, and mechanical engineers who need a consistent 90° 1:1 transmission ratio across a wide tooth range.
Each gear is machined from 45# medium-carbon steel, offering a solid balance of hardness and toughness. The 2 Module (Mod 2) pitch standard means a tooth pitch of 6.28 mm, with outer diameters spanning 32.5 mm (15T) to 82.5 mm (40T) — approximately 1.28 in to 3.25 in. Tooth counts available: 15T, 16T, 17T, 18T, 19T, 20T, 21T, 22T, 23T, 24T, 25T, 26T, 27T, 28T, 29T, 30T, 31T, 32T, 33T, 34T, 35T, 36T, 38T, and 40T.
Typical use cases include DIY gearbox builds requiring 90-degree shaft redirection, small-scale CNC axis drives needing a compact bevel gear pair, and robotics joint mechanisms where a 1:1 bevel gear set keeps torque transfer symmetrical. The 45# steel construction also suits light industrial automation fixtures and educational mechanical engineering models.
🔩 45# Medium-Carbon Steel Construction
Machined from 45# steel for a reliable combination of surface hardness and core toughness, reducing tooth fatigue under cyclic loading in continuous-duty applications.
📐 Module 2 Precision Tooth Profile
Standardized Mod 2 pitch (6.28 mm tooth pitch) ensures interchangeability with other Mod 2 components and predictable mesh geometry across the full 15T–40T range.
🔄 True 90° Mesh Angle, 1:1 Ratio
Engineered for perpendicular shaft arrangements with a 1:1 speed and torque ratio — ideal for symmetric drive systems where input and output RPM must remain equal.
📏 Wide Tooth Count Selection (15T–40T)
Twenty-four tooth count options from 15T to 40T let you match the gear to your shaft spacing and torque requirements without custom machining.
🛡️ Consistent OD Tolerance Across Variants
Outer diameters range from 32.5 mm to 82.5 mm in predictable 2 mm increments per tooth, making layout and housing design straightforward for mechanical designers.
📦 Flexible Pack Quantities (1, 2, or 5 PCS)
Available in single-piece, 2-piece, or 5-piece packs — order a matched pair for a single axis or stock up for multi-axis builds and prototyping runs.
