Engineers, robotics builders, and precision DIY machinists need a bevel gear set that meshes consistently, runs quietly, and holds its geometry under load. This Module 1 aluminium bevel gear set delivers exactly that — a matched 1:1 ratio pair engineered for repeatable, low-backlash right-angle transmission.\u003c\/p\u003e\n\u003cp\u003eEach set consists of two identical bevel (miter) gears machined from aluminium alloy, available in 15, 20, 25, or 30 tooth configurations. Bore diameters range from 4mm to 12mm (~0.16\" to ~0.47\"), with select variants offering a 3mm or 4mm keyway for positive shaft locking. Module 1 pitch ensures compatibility with standard M1 gear systems across metric drivetrain designs.\u003c\/p\u003e\n\u003cp\u003eTypical applications include desktop CNC axis drives requiring compact right-angle gearing, robotics joint assemblies where a lightweight aluminium miter gear set reduces inertia, and custom automation or 3D-printer extruder mechanisms that benefit from a precision bevel gear pair with consistent tooth engagement.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for Module 1 (M1) metric gear systems.

Instead, choose based on physical size and load: a 15T gear has a smaller pitch diameter (~15mm) and suits compact, lightweight builds, while a 30T gear (~30mm pitch diameter) offers more tooth contact area and handles higher torque loads. Match the gear's outer diameter to the space available in your assembly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat bore size should I select for my motor shaft?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eMeasure your motor or drive shaft diameter precisely with calipers. Select the bore size that matches — for example, a 6mm shaft requires the 6mm bore variant. If your shaft is between sizes, do not select a smaller bore; instead, choose the next size up and use a shaft collar or set screw to secure it. For shafts requiring positive locking under high torque, choose a keyway variant.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhen should I choose a keyway bore variant?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eKeyway variants are recommended when the gear must transmit significant torque without slipping on the shaft. A set screw alone can loosen under vibration or reversing loads. The 3mm keyway (for 8mm bore) and 4mm keyway (for 10mm and 12mm bore) variants accept a standard parallel key, providing a positive mechanical connection between the gear and shaft. For light-duty or low-torque applications, a standard bore with a set screw is typically sufficient.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these gears compatible with steel or brass M1 bevel gears?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes — Module 1 is a standardised metric pitch, so these aluminium gears will mesh correctly with any other M1 bevel gear of the same tooth count and pressure angle, regardless of material. However, when pairing aluminium with steel gears under heavy load, be aware that aluminium teeth will wear faster. For mixed-material pairings in high-load applications, consider replacing both gears with the same material or using the aluminium set in lighter-duty roles.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow strong are aluminium bevel gears compared to steel?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eAluminium alloy gears offer a good strength-to-weight ratio and are well-suited for light to medium duty applications such as robotics, 3D printers, CNC axis drives, and automation equipment. They are significantly lighter than steel, which reduces inertia in dynamic systems. For heavy industrial loads, continuous high-torque operation, or abrasive environments, steel gears are generally more durable. These aluminium miter gears are designed for precision, weight-sensitive builds rather than heavy industrial use.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo these gears require lubrication?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eLight lubrication is recommended for extended service life, particularly in continuous-duty applications. A thin film of white lithium grease or a dry PTFE lubricant applied to the tooth faces at installation will reduce wear and noise. For intermittent or low-speed applications (such as manual positioning mechanisms), lubrication is beneficial but not strictly required.
