When your drivetrain needs to change direction without losing torque, a poorly matched bevel gear set becomes the weakest link in your build. Makers, robotics enthusiasts, and mechanical engineers working on CNC machines, conveyor systems, or custom gearboxes need bevel gears that mesh cleanly and hold up under repeated load cycles. This pack of 20 Module 2 bevel gears with 24 teeth is sized and machined to deliver consistent angular power transfer at 90° shaft intersections.
Each gear in this set is machined from carbon steel, offering a balance of hardness and machinability suited to moderate-load mechanical drives. The module (Mod) rating of 2 defines the tooth size and pitch, with an outer diameter of 50.5 mm (approximately 1.99 in) and a bore diameter typically in the 8–12 mm range depending on variant. The 24-tooth count produces a 1:1 ratio when paired with a matching 24T bevel gear, or can be combined with different tooth counts for speed/torque adjustment.
Typical applications include DIY robotic arm joints requiring 90° shaft redirection, CNC router axis drives where compact bevel sets replace bulky worm gears, and custom conveyor or automation builds where a 2 Mod bevel gear pair provides smooth, low-backlash transmission. The 20-piece pack supports prototyping, replacement stocking, or multi-axis builds from a single order.

The bore diameter must match your shaft's outer diameter for a secure fit. Check the variant options listed above for available bore sizes. If none match your shaft exactly, the carbon steel construction allows for careful machining to open the bore — consult a machine shop if you need a custom fit.
Yes. As long as both gears share the same Module (Mod 2), you can pair a 24T with a different tooth count bevel gear to achieve a speed or torque ratio other than 1:1. For example, pairing a 24T with a 12T gives a 2:1 ratio. Confirm the mating gear's module before ordering.
These carbon steel bevel gears are suited for moderate-load, continuous-duty applications such as robotics joints, CNC axis drives, and light conveyor systems. For heavy industrial loads or shock-load environments, verify the torque rating against your application requirements and consider hardened or heat-treated variants if available.
Carbon steel has moderate corrosion resistance. For outdoor or high-humidity environments, applying a light machine oil or grease coating during installation will extend service life. If your application demands higher corrosion resistance, look for stainless steel or zinc-plated bevel gear variants.
These gears are designed for 90° intersecting shaft configurations — the most common bevel gear application. They are not intended for skewed (non-intersecting) or non-90° shaft arrangements without engineering verification.
The 20PCS pack is ideal for multi-axis builds that require several gear pairs, prototyping phases where you may test multiple configurations, or stocking replacement gears to minimize downtime. Buying in a pack also reduces per-unit cost compared to sourcing individual gears for each axis.
Confirm three things: (1) the module — your existing gear must be Module 2; (2) the shaft angle — your gearbox must use 90° intersecting shafts; (3) the bore diameter — select the variant that matches your shaft size. If you are unsure, contact us with your gearbox model or shaft dimensions and we will help confirm compatibility.
