20 Pack 9 Teeth Plastic Worm Reduction Gears Model 092A for DIY Craft Subjects Product overview A set of 20 plastic reduction worm gears, each with 9 teeth and identified as model 092A. These gears are intended for use in worm gear assemblies as replacement parts or components for hobby and DIY craft projects. Key benefits Ready supply: 20 identical gears in one pack reduce downtime for repairs and speed up prototyping. Consistent fit: 9tooth profile ensures repeatable meshing with matching worm pinions for predictable reduction ratios. Lightweight material: plastic construction keeps weight low for small mechanisms and minimizes added load on motors. Quiet operation: plastic gear engagement helps reduce noise in low to moderate load applications. Versatile use: suitable for hobby projects, educational builds, and model assemblies where compact reduction gearing is required. Function and compatibility Function: designed as reduction worm gears to convert rotational input from a worm pinion into reduced speed and increased torque at the gear wheel. Compatibility: model 092A 9tooth plastic gears are compatible with miniature worm gear setups and common small gearboxes used in DIY craft subjects and hobby electronics. Confirm shaft and mating pinion dimensions when replacing or upgrading parts. Material and performance Material: molded plastic appropriate for lightweight, lowfriction gear operation. Performance: intended for low to moderate torque applications such as hobby robotics, scale models, and small mechanical assemblies. Not intended for heavy industrial loads. Typical applications Hobby robotics: use as reduction gears in small robot drivetrains, actuator assemblies, or geared motors to increase torque for joint movement or wheel drive. Scale modeling and RC: worn gears in model gearboxes, servos, or custom transmission assemblies for RC vehicles and model displays. Educational and DIY craft projects: ideal for STEM kits, school projects, and custom craft mechanisms that require compact reduction gearing. What you get Quantity: 20 plastic gears Teeth: 9 teeth per gear Model: 092A Intended use: reduction worm gear applications for DIY craft subjects and similar small mechanisms Installation notes Verify mating pinion and shaft sizes before installation to ensure proper engagement and alignment. Suitable for common attachment methods used in hobby assemblies. For results, test gear mesh and clearances in prototypes before final assembly. Use this 20 pack of model 092A 9tooth plastic worm reduction gears to keep projects moving, worn parts, and build small, quiet reduction gear systems for a variety of hobby and educational applications.
