Uxcell Mod1 M1 Pinion Motor Gear Set, 29T/30T, for 5mm RC Motor Shaft, M1 Pitch Gear for RC Cars, Includes Hex Wrench, 2 Pieces

1. Diameter Pitch: 48DP, Gear Aperture: 5mm, Gear Height: 14mm, Number of Teeth: 29T/30T 2. Mod 1 refers to the pitch of each pinion gear tooth, and 29T/30T refers to the number of pinion gear teeth. Make sure the spur gear and pinion gear have the same pitch. Otherwise, the teeth will not mesh. 3. This RC car pinion gear set is made of high-quality 45# steel, making it durable and reusable for hours of fun RC racing. 4. Superior machining results in smooth rotation with less harshness and noise compared to other pinions. 5. Speeds vary depending on the gear ratio. We offer pinion gears with various tooth sizes to expand your gear ratio options. 6. This pinion gear set is made of hardened steel and can be used with steel spur gears. Do not use with plastic or aluminum spur gears. Start with the smallest teeth first. Then upgrade to larger teeth, periodically checking the motor temperature during operation. Ultimately, you'll be able to control high speeds while avoiding potential risks. 7. Package Includes: 2 x Mod 1 Pinion Gears, 2 x Grub Screws, 1 x Hex Wrench Size - Mod 1 refers to the pitch of each tooth on the pinion gear, and 29T and 30T refer to the number of teeth on the pinion gear. Make sure the pitch of the spur gear and pinion gear are the same, otherwise the teeth will not mesh. Material - This RC car pinion gear set is made of high-quality 45# steel, making it durable and reusable for hours of fun RC racing. Features - Excellent machining results in smooth rotation with less roughness and noise compared to other pinions. Applications - Speeds vary depending on the gear ratio. We offer pinion gears with various tooth sizes to increase your gear ratio options. Note - This pinion gear set is made of hardened steel and can be used with steel spur gears. Do not use with plastic or aluminum spur gears. You can start with the smallest teeth first. Next, upgrade to larger teeth and periodically check the motor temperature while driving. Finally, you'll be able to control high speeds while avoiding potential risks.
