Engineers, robotics hobbyists, and automation makers who need a corrosion-resistant, dimensionally consistent worm gear set will find this 1 module stainless steel worm wheel gear and worm shaft combination purpose-built for the task.\u003c\/p\u003e\n\u003cp\u003eThis listing covers a complete range of 1 module (Mod 1) worm gears and matching worm shafts machined from stainless steel. Worm wheel gears are available in 15T, 20T, 25T, 30T, 35T, 40T, 50T, and 60T tooth counts; worm shafts are offered in A-Type and B-Type configurations. Bore diameters span 5 mm (0.197 in) to 12 mm (0.472 in), accommodating a wide range of motor and shaft sizes. Gear outer diameters scale with tooth count, typically ranging from approximately 17 mm (0.67 in) for 15T up to approximately 62 mm (2.44 in) for 60T.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include low-speed high-torque actuators for CNC axis drives, compact worm-drive gearboxes for robotic arm joints, motorized camera pan-tilt rigs requiring self-locking behavior, and conveyor indexing mechanisms in light industrial automation. The stainless steel construction makes these gears well-suited for environments with moisture exposure, such as food-adjacent equipment or outdoor robotics platforms.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for 1 Module (Mod 1) worm gear systems.
