It is used to transfer rotational motion from the motor to other components, such as the drive shaft or spur gear, allowing the model to move forward or backward. - Gear Pitch: 48P(48DP); Number of Teeth: 17T/18T/19T/20T/21T; Inner Diameter: 3.175mm/0.125 inch; Diameter: 10.07mm/0.4 inch, 10.6mm/0.42 inch, 11.13mm/0.44 inch, 11.66mm/0.46 inch, 12.19mm/0.48 inch; Height: 9mm/0.35 inch; Material: Aluminum 7075 - The pinion gear is made of aluminum 7075, which is durable and wear-resistant. It can effectively resist deformation. It provides smoother and more efficient power transfer from the motor, resulting in improved acceleration and top speed. - Steps of installation: 1. Slide the RC Hardened Pinion Gear onto the motor shaft; 2. Align the teeth with the corresponding gears it will mesh with (such as the spur gear); 3. Ensure that the gear is securely seated on the shaft. - Please check if your spur gear and pinion gear have the same pitch, otherwise the teeth won't mesh. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | sourcing map | | Part number | a23121600ux0172 | | Item Weight | 9.07 g | | Package Dimensions | 14 x 10.01 x 1.19 cm; 9.07 g | | Manufacturer reference | a23121600ux0172 | | Colour | Gold | | Material | Aluminium | | Batteries Required? | No | ## Product Details - **Brand:** sourcing map - **Material:** Aluminium - **Shaft diameter:** 3.18 Millimetres - **Manufacturer:** sourcing map ## Images ![5Pcs RC 48DP Motor Pinion Gear 3.175mm Shaft 17T/18T/19T/20T/21T Hardened Pinion Gears Aluminum for 1/10 1/12 RC Model Car, RC Motor - Image 1](https://m.media-amazon.com/images/I/611cwXC6vNL.jpg) ## Frequently Bought Together - sourcing map 5Pcs RC 48DP Motor Pinion Gear 3.175mm Shaft 17T/18T/19T/20T/21T Hardened Pinion Gears Aluminum for 1/10 1/12 RC Model Car, RC Motor - Tamiya 300053068 Electric Motor 540 Sport Tuned - 500Pcs RC Screw Kit RC Repair Tool Kit M3 M4 Hex Screws Nut Shell Buckle Hardware Fastener for 1/8 1/10 1/12 Scale RC Cars Truck Crawler DIY Parts --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/625835198-5pcs-rc-48dp-motor-pinion-gear-3-175mm-shaft-17t](https://www.desertcart.jp/products/625835198-5pcs-rc-48dp-motor-pinion-gear-3-175mm-shaft-17t) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-10*
