When your mechanical build demands a reliable right-angle power transfer, a mismatched or undersized bevel gear becomes the weakest link in the entire drivetrain. Engineers, machinists, and serious DIY builders working on CNC machines, robotics platforms, and industrial automation need a miter gear that holds tight tolerances under load — without corroding, seizing, or wearing prematurely. This Module 2 stainless steel bevel gear is designed for exactly those conditions.
Each gear is machined from stainless steel and cut to Module 2 (2mm tooth pitch) specification. Available in three tooth counts — 20T, 25T, and 30T — with a 1:1 pairing ratio for true 90° miter drive. Bore sizes range from 12mm to 30mm (approximately 0.47″ to 1.18″), each paired with a precision-cut keyway (4mm, 5mm, or 8mm depending on bore) for positive shaft engagement. Sold individually (1 pcs) or as a matched pair (2 pcs).
Typical use cases include right-angle gearbox assemblies for CNC router Z-axis drives, bevel gear sets for robotic joint actuators, and 90° shaft redirection in conveyor and indexing table mechanisms — all applications where a module 2 miter gear with keyway bore delivers consistent torque transfer without backlash creep.
Standardized 2mm module ensures interchangeability with any Module 2 mating gear. Consistent tooth geometry across all tooth counts (20T / 25T / 30T).
Precision-ground 90° pitch cone angle delivers accurate right-angle power transmission with no speed change — ideal for symmetric bevel gear pairs.
Corrosion-resistant stainless steel body withstands moisture, mild chemicals, and demanding workshop environments without surface degradation.
Each bore option includes a precision-cut keyway (4mm, 5mm, or 8mm) to eliminate shaft slip under torque. Bore range: 12mm to 30mm (0.47″–1.18″).
Order 1 pcs for replacement or prototyping, or select 2 pcs to receive a complete matched miter gear pair ready for direct installation.
Choose from 20-tooth, 25-tooth, or 30-tooth variants to match your pitch diameter and center distance requirements across different drivetrain layouts.

All three options share the same 1:1 ratio and 90° miter angle, so the choice depends on your required pitch diameter and center distance. A 20-tooth gear gives a 40mm pitch diameter, 25-tooth gives 50mm, and 30-tooth gives 60mm. Select based on the space available in your assembly and the center distance between the two shafts.
Match the bore diameter to your shaft OD. The keyway width is fixed per bore range: 4mm keyway for 12mm bore, 5mm keyway for 14mm–18mm bores, and 8mm keyway for 20mm–30mm bores. Measure your shaft diameter precisely before selecting — a loose bore fit will cause runout and premature wear.
For a complete 90° miter drive, you need two matching bevel gears (same module, same tooth count). Select the "2 pcs" amount option to receive a matched pair. The "1 pcs" option is suitable for replacing a single worn gear or for prototyping when you already have the mating gear.
Stainless steel offers a good balance of tensile strength (typically 515–860 MPa depending on grade) and corrosion resistance. It is well-suited for light-to-medium duty drives, robotics, food-adjacent equipment, and humid or wet environments. For very high-torque industrial gearboxes, consult your load calculations against the gear's rated capacity.
Stainless steel provides inherent corrosion resistance due to its chromium oxide passive layer, making these gears suitable for damp workshops, outdoor enclosures, and light washdown environments. For prolonged submersion or highly acidic/alkaline exposure, additional sealing or a higher-grade stainless alloy may be advisable.
As precision-machined Module 2 gears, backlash is held to standard commercial tolerances. For applications requiring minimal backlash (e.g., CNC positioning axes), ensure proper gear mesh adjustment during installation — center distance and cone apex alignment directly affect backlash. Contact us to confirm tolerance class if your application is backlash-critical.
Yes — Module 2 is an international standard (ISO 1328). These gears will mesh correctly with any other Module 2 bevel gear of the same tooth count and 20° pressure angle, regardless of brand, provided the shaft angle is also 90° and the cone apex is correctly aligned.
