uxcell RC 48DP Hardened Aluminum Pinion Gears for 110112 RC Model Cars, 3.175mm Shaft, 20T21T22T23T24T, 5 Pieces

RC hardened gears are often used in remote-controlled (RC) models, such as RC cars, trucks, boats, and drones. They are used to transfer rotational motion from the motor to other components, such as drive shafts or spur gears, allowing the model to move forward or backward. Gear Pitch: 48P (48DP), Number of Teeth: 20T/21T/22T/23T/24T, Inner Diameter: 3.175mm, Diameters: 11.66mm, 12.19mm, 12.72mm, 13.25mm, 13.78mm, Height: 9mm, Material: Aluminum 70-75. The pinion gear is made of durable, wear-resistant aluminum 70-75, which effectively resists deformation. This ensures smoother and more efficient power transmission from the motor, improving acceleration and speed. Installation Instructions: 1. Slide the RC hardened pinion gear onto the motor shaft. 2. Align the teeth with the corresponding gear (such as a spur gear) to mesh with it. 3. Make sure the gear is securely fastened to the shaft. Make sure the spur gear and pinion gear have the same pitch, otherwise the teeth will not mesh.
