1.5 Modulus Bevel Gear — Precise 90° Power Transmission for DIY and Mechanical Builds

When your project demands a reliable right-angle drive — whether you're building a CNC axis, a robotic joint, or a custom gearbox — mismatched or imprecise bevel gears cause backlash, noise, and premature wear. These 1.5 modulus bevel gears are engineered for makers, mechanical engineers, and DIY builders who need accurate 90° torque transfer without compromise.

Each gear is individually machined from steel for durability. Available in 15T pinion or 30T ring gear, with bore options ranging from 5 mm (0.20 in) to 15 mm (0.59 in), covering the most common shaft diameters used in hobby and light-industrial applications. The 1.5 modulus tooth profile ensures smooth meshing and consistent load distribution across the gear face.

Typical use cases include right-angle gearbox assemblies for CNC router Z-axes, servo-driven robotic arm joints requiring 1:2 speed reduction, and custom differential drive mechanisms in RC vehicles or automation rigs. Long-tail search terms like "1.5 mod 90 degree bevel gear" and "15T 30T steel bevel gear" reflect exactly what this product delivers.

⚙️ Compatibility: Designed for 1.5 modulus gear systems. Select your gear model (15T pinion or 30T ring gear) and bore diameter to match your shaft size — available in 5, 6, 8, 10, 12, and 15 mm. Each order is for one individual gear.

Key Features

  • 📐 True 90° Mesh Angle — Engineered for precise 90° shaft angle meshing, enabling clean right-angle power transmission with minimal backlash in your drivetrain.
  • ⚙️ 1:2 Speed Reduction Ratio — The 15T/30T tooth count pairing delivers a fixed 1:2 ratio, ideal for torque multiplication in servo-driven or motor-driven mechanical assemblies.
  • 🔩 Wide Bore Range: 5–15 mm — Six bore sizes (5, 6, 8, 10, 12, 15 mm) accommodate the most common shaft diameters used in hobby motors, stepper shafts, and light-industrial drives.
  • 🛡️ Steel Construction for Load Durability — Machined from steel, these gears handle continuous rotational loads without deforming under torque, suitable for both intermittent and sustained drive cycles.
  • 🔄 1.5 Modulus Tooth Profile — The 1.5 mod tooth geometry provides a balance between tooth strength and compact gear diameter, fitting tightly spaced mechanical enclosures without sacrificing load capacity.
  • 🎯 Sold Individually — Choose Your Model — Select the 15T pinion or 30T ring gear based on your build requirements. Purchase the specific gear you need without paying for parts you already have.

Frequently Asked Questions

How do I choose the right bore size for my shaft?

Measure your motor or drive shaft diameter with a caliper. Select the bore option that matches exactly — for example, a NEMA 17 stepper typically uses a 5 mm shaft, while larger servo motors often use 8–12 mm shafts. A bore that is too large will require a setscrew or keyway adapter to prevent slipping.

Is this sold as a single gear or as a set?

Each order is for one individual gear — either the 15T pinion or the 30T ring gear, based on your selection. If you need both gears to form a complete 1:2 bevel gear pair, please add each model separately to your cart.

What is the gear ratio and what does it mean for my build?

When used together, the 15T/30T pairing produces a 1:2 ratio — for every two rotations of the input (pinion) shaft, the output (ring gear) shaft completes one rotation. This halves the speed and doubles the torque at the output, which is useful for servo-driven joints or motor-driven axes where you need more torque at lower RPM.

Are these gears corrosion-resistant for outdoor or humid environments?

These gears are machined from steel, which provides good mechanical strength but has moderate corrosion resistance. For outdoor or high-humidity applications, we recommend applying a light machine oil or grease coating, or considering a stainless steel alternative if long-term corrosion resistance is critical.

What is the maximum torque or RPM these gears can handle?

Exact torque and RPM ratings depend on the specific bore variant, lubrication, and operating conditions. As a general guideline for 1.5 modulus steel bevel gears of this size, they are suited for light-to-medium duty applications — typically hobby CNC, robotics, and small automation rigs. Contact us to confirm suitability for high-load or high-speed applications.

Can I use this gear with a different mating gear from another brand?

While the 1.5 modulus tooth profile is a standard, mixing with gears from different manufacturers may result in mesh errors or backlash due to slight variations in pressure angle and tooth geometry. For best results, pair the 15T and 30T gears from the same listing.

What applications are these bevel gears best suited for?

These 1.5 modulus bevel gears are well-suited for CNC machine right-angle drives, robotic arm joints, RC vehicle differentials, custom gearbox assemblies, and any DIY mechanical project requiring a 90° change in shaft direction with a 1:2 speed reduction.
