When a slipping or mismatched gear brings your build to a halt, the root cause is almost always a component that wasn't machined to spec. Engineers, makers, and automation technicians who need a reliable worm gear wheel — one that holds tight tolerances under continuous load — will find this module 1 stainless steel worm gear wheel a dependable solution for both prototype and production applications.
Each worm gear wheel is machined from A2 stainless steel, delivering solid corrosion resistance alongside the structural integrity needed for mechanical power transmission. The module 1 tooth profile is precision-cut to mesh cleanly with a matching module 1 worm shaft. Tooth counts range from 15T to 60T, with bore diameters from 5 mm (≈0.20 in) to 12 mm (≈0.47 in). Both A Type and B Type hub configurations are available in select bore sizes.
Typical use cases include low-speed, high-torque drive stages in CNC router axes, robotic joint actuators, conveyor indexing mechanisms, and DIY motorized camera sliders — anywhere a compact worm-drive reduction is needed with minimal backlash and long service life.

The tooth count determines your gear reduction ratio when paired with a single-start worm shaft. A 15T gear gives approximately 15:1 reduction; a 60T gear gives approximately 60:1. Higher tooth counts produce more torque multiplication and lower output speed. Choose based on your required output RPM and torque, then verify the resulting outer diameter fits your housing.
Match the bore diameter to your shaft's outer diameter. Available bores are 5, 6, 8, 10, and 12 mm. If your shaft is metric and falls between these sizes, you will need to machine the bore to fit — do not force a gear onto an oversized shaft. Always confirm your shaft diameter with calipers before ordering.
A Type hubs have a longer hub extension, providing more contact area along the shaft for applications where axial load or shaft engagement length matters. B Type hubs are shorter, suited for compact housings with limited axial space. Both types use the same Module 1 tooth profile and mesh identically with a compatible worm shaft.
A2 stainless steel (equivalent to 304 grade) offers solid resistance to atmospheric corrosion, moisture, and mild chemical exposure. It is suitable for humid environments, light washdown conditions, and outdoor-adjacent installations. For highly aggressive chemical environments or saltwater immersion, consider consulting a materials engineer for a higher-grade alloy.
Yes — any Module 1 worm gear wheel will mesh with any Module 1 worm shaft, provided the pressure angle also matches (typically 20°). Always confirm the module and pressure angle of your worm shaft before pairing. Mismatched modules will not mesh correctly and can cause rapid wear or binding.
Yes. These worm gear wheels are suited for continuous-duty mechanical power transmission in applications such as CNC axis drives, robotic joint actuators, conveyor indexers, and motorized positioning stages. Ensure adequate lubrication at the worm-gear interface and that the gear is not operated beyond its rated load for the selected tooth count and bore size.
