Key benefits Durable steel construction delivers reliable wear resistance for gear trains in small assemblies. Precise modulus 0.3 and 17 teeth provide consistent torque transmission and smooth meshing with compatible gears. Compatible with electronic starter shafts of 1.5 mm or 2 mm diameter, offering flexible integration into various designs. Compact, lightweight gear suitable for tight spaces in micro gearboxes, robotics, and hobby electronics. Simple replacement option to extend the life of gear assemblies and maintain performance. Key attributes Modulus: 0.3 Teeth: 17 Material: Steel Gear type: Transmission gear Shaft hole compatibility: 1.5 mm or 2 mm diameter Applications: Small gear transmission components for electronic starters and related assemblies Specifications and compatibility The gear is designed as a steel metal gear transmission with 17 teeth and a modulus of 0.3. It is suitable for assemblies that use a shaft hole of 1.5 mm or 2 mm, enabling flexible use across common starter and micro drive configurations. Built for durability in longerrunning gear engagements, reducing wear in routine operation. Performance characteristics Steel construction provides robust strength and wear resistance under typical operating loads. The 17tooth configuration with modulus 0.3 supports reliable meshing with compatible gears, contributing to stable torque transfer and predictable performance. Precision in the gear profile supports smooth engagement and minimizes play in compatible gear trains. Use cases Replacement gear in a small electronic starter or micro drive system that uses a 1.5 mm or 2 mm shaft, restoring torque transmission and reliability. Part of a compact gear reduction assembly in micro robots, educational kits, or DIY electronics projects requiring a durable steel gear with a 1.5/2 mm shaft interface. Upgrade or component in hobby RC gearboxes where a steel 17tooth, 0.3 modulus gear improves longevity and consistency of drive performance. Notes This gear is intended to fit specific shaft diameters and gear train configurations. Confirm compatibility with your existing gearbox or starter assembly before . The description reflects the specifications implied by the product title: 0.3M modulus, 17 teeth, steel material, and 1.5 mm or 2 mm shaft hole.
