More teeth (e.g., 30T) produce a larger gear with a greater pitch circle, which can distribute load over more contact area. Fewer teeth (e.g., 16T) result in a more compact assembly.

A keyway variant adds a machined slot that accepts a key, creating a positive mechanical lock that prevents rotational slipping under load. If your application involves significant torque, reversing loads, or vibration, a keyway bore is strongly recommended. For light-duty or low-torque builds, a plain bore with a set screw is typically sufficient.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eAre these gears strong enough for my robot or CNC project?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eEngineering-grade nylon offers a good strength-to-weight ratio for moderate-load applications such as desktop robots, small CNC axes, and educational mechanisms. Nylon is not recommended for high-torque industrial drives or applications with sustained heavy loads. If your torque requirements exceed what nylon can handle, consider a metal bevel gear set instead. For typical maker and hobbyist builds, these gears perform reliably.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eHow resistant are nylon bevel gears to moisture and corrosion?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eNylon has inherent corrosion resistance and will not rust, making it suitable for humid environments where metal gears would degrade. However, nylon can absorb moisture over time, which may cause slight dimensional changes. For outdoor or wet environments, ensure the gear housing provides adequate protection. For fully waterproof applications, verify dimensional tolerances after moisture exposure.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWill these gears mesh with my existing Module 1.5 metal gears?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eYes — Module 1.5 is a standardized tooth profile, so these nylon bevel gears are geometrically compatible with other Module 1.5 bevel gears regardless of material. However, mixing nylon and metal gears will cause the softer nylon gear to wear faster. For longest service life, pair nylon with nylon. If you must mix materials, treat the nylon gear as the replaceable wear component.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between the plain bore and keyway bore variants?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003ePlain bore variants have a smooth cylindrical hole sized to your shaft diameter and are typically secured with a set screw (not included). Keyway variants have an additional rectangular slot machined into the bore that accepts a standard key (sold separately), providing a positive rotational lock. The keyway dimensions vary by bore size: 4 mm keyway for 10–12 mm bores, 5 mm keyway for 14–16 mm bores, and 6 mm keyway for 18–20 mm bores.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eCan I use these gears at high RPM?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eNylon bevel gears are suitable for moderate RPM ranges typical of maker and hobbyist applications.
